Detailed Implementation

[0080] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0081] In recent years, with the rapid development of technologies for detecting the composition and content of substances, water quality testing and hardness testing have been widely applied in fields such as geological exploration and wastewater treatment. Calcium and magnesium ions are essential nutrients for the human body, but they are also major causes of scale buildup, leading to blockages or damage to equipment and pipes. Furthermore, the concentration of calcium and magnesium ions serves as a measure of water hardness. Therefore, detecting the concentration of calcium and magnesium ions in the solution being tested is particularly crucial.

[0082] In related technologies, each ion has a specific series of absorption spectra. The transition spectrum of each ion in its lowest energy level is called the first recommended spectrum of that ion. The wavelength corresponding to the first recommended spectrum of calcium ion is 317.933 nm, and the wavelength corresponding to the first recommended spectrum of magnesium ion is 285.213 nm. Based on the characteristics of calcium and magnesium ions at this wavelength, the wavelengths corresponding to the first recommended spectrum of calcium and magnesium ions are usually used as the detection wavelength. The absorption spectrum of the solution to be tested under ultraviolet light at the detection wavelength is analyzed to realize the concentration detection of calcium and magnesium ions.

[0083] However, when detecting calcium and magnesium ion concentrations using relevant technologies, the absorption spectra of solutions with different calcium and magnesium ion concentrations under ultraviolet light at the detection wavelength show little difference. When the concentration of calcium and magnesium ions is low, it is difficult to accurately identify the concentration of calcium and magnesium ions, resulting in low detection accuracy and sensitivity. This can lead to problems such as failure to obtain detection results or excessively large errors in the detection results.

[0084] Based on this, an exemplary embodiment of this disclosure provides a detection device that, through a capillary, a light source, a photodetector, and a controller, can acquire first absorbance information of calcium and magnesium ions in a solution under ultraviolet light of a first preset wavelength. The controller then determines the calcium and magnesium ion concentration corresponding to the first absorbance information based on the first absorbance information and first preset configuration information, thereby realizing the detection of calcium and magnesium ion concentration. By limiting the first preset wavelength to greater than or equal to 200 nm and less than or equal to 254 nm, the concentration of calcium and magnesium ions corresponding to the first absorbance information can be accurately obtained by leveraging the characteristic that calcium and magnesium ions absorb ultraviolet light within this wavelength range. This ensures the accuracy of the calcium and magnesium ion concentration test results and improves detection precision and sensitivity.

[0085] In one exemplary embodiment, a detection method is provided for detecting the concentration of calcium and magnesium ions in a solution to be detected, with reference to... Figure 1 As shown, the detection methods include:

[0086] S100. Obtain the first absorbance information of calcium and magnesium ions in the solution to be detected under ultraviolet light of a first preset wavelength, wherein the first preset wavelength is greater than or equal to 200 nm and less than or equal to 254 nm.

[0087] In step S100, the components of the solution to be tested may include, for example, pure water, calcium and magnesium ions, and other interfering solutes, with the calcium and magnesium ion concentration being the overall concentration of calcium and magnesium ions. The first absorbance information may include, for example, the absorbance value of calcium and magnesium ions under ultraviolet light of a first preset wavelength, where the absorbance value is the absorption rate of the substance to light radiation. It should be noted that the absorbance value can be obtained, for example, by detecting the output light power of the solution to be tested under the light source using a spectrophotometer and converting the output light power into the corresponding absorbance value.

[0088] S200. Based on the first absorbance information and the first preset configuration information, determine the calcium and magnesium ion concentration corresponding to the first absorbance information. The first preset configuration information is used to characterize the correspondence between absorbance information and calcium and magnesium ion concentration.

[0089] In step S200, the first preset configuration information can be characterized, for example, by the absorption spectrum curves of calcium and magnesium ions. For instance, standard absorption spectrum curves of calcium and magnesium ions at different concentrations are shown below. Figure 2 and Figure 3 As shown in the figure, the horizontal axis represents the wavelength of the light source, and the vertical axis represents the absorbance value. Different concentrations of calcium and magnesium ions have different absorbance values ​​under the same wavelength light source. Therefore, the corresponding calcium and magnesium ion concentration can be determined based on the absorbance value of calcium and magnesium ions under ultraviolet light at a first preset wavelength. For example, when the first absorbance information includes a calcium and magnesium ion absorbance value of 1.79% under ultraviolet light at a wavelength of 204 nm, the calcium and magnesium ion concentration corresponding to this absorbance information can be determined to be 1 mg / L based on the first preset configuration information.

[0090] Depend on Figure 2 and Figure 3 It can be seen that the difference in absorbance values ​​between different concentrations of calcium and magnesium ions in the wavelength range of 200nm to 254nm is more obvious than in other wavelength ranges. Moreover, the wavelength is not too small, which would make it difficult to obtain the absorbance value. Setting the first preset wavelength to be greater than or equal to 200nm and less than or equal to 254nm can distinguish the different calcium and magnesium ion concentrations corresponding to different absorbance values ​​under the same wavelength of ultraviolet light. Thus, the corresponding calcium and magnesium ion concentration can be accurately determined based on the first absorbance information of calcium and magnesium ions under ultraviolet light at the first preset wavelength.

[0091] The first preset configuration information can also be a data set consisting of multiple data points, where each data point represents a different calcium and magnesium ion concentration value corresponding to a different absorbance range under ultraviolet light at a first preset wavelength. The first absorbance information of calcium and magnesium ions under ultraviolet light at the first preset wavelength can be used to determine the corresponding calcium and magnesium ion concentration based on the calcium and magnesium ion concentration value corresponding to the absorbance value in the data set.

[0092] In this embodiment, by acquiring the first absorbance information of calcium and magnesium ions in the solution to be tested under ultraviolet light at a first preset wavelength, the concentration of calcium and magnesium ions corresponding to the first absorbance information can be determined based on the first absorbance information and the first preset configuration information used to characterize the correspondence between absorbance information and calcium and magnesium ion concentrations. This achieves the acquisition of the calcium and magnesium ion concentration in the solution to be tested. By limiting the first preset wavelength to greater than or equal to 200 nm and less than or equal to 254 nm, the concentration of calcium and magnesium ions corresponding to the first absorbance information can be accurately obtained based on the significant differences in absorbance values ​​corresponding to different concentrations of calcium and magnesium ions within this wavelength range. This ensures the accuracy of the calcium and magnesium ion concentration test results and improves detection precision and sensitivity.

[0093] In some embodiments, reference Figure 4 As shown, the first absorbance information of calcium and magnesium ions in the solution to be detected under ultraviolet light of a first preset wavelength is obtained, including:

[0094] S110. Obtain the second absorbance information of the interfering solute in the solution to be tested under ultraviolet light of the second preset wavelength. Under ultraviolet light of the second preset wavelength, the interfering solute can absorb ultraviolet light, and the absorbance value of calcium and magnesium ions is less than or equal to the absorbance threshold.

[0095] In step S110, the interfering solute in the solution to be tested may include, for example, total organic carbon (TOC) in water. Under ultraviolet light of a second preset wavelength, the interfering solute can absorb ultraviolet light, i.e., the interfering solute has an absorbance value. The absorbance value of calcium and magnesium ions is less than or equal to the absorbance threshold, which may be, for example, 0. When the absorbance value of calcium and magnesium ions is less than the absorbance threshold, the absorbance value of calcium and magnesium ions is negligible compared to the absorbance value of the solution to be tested. In this case, the solution to be tested is tested to obtain the second absorbance information of the interfering solute in the solution under ultraviolet light of the second preset wavelength. The second absorbance information may include, for example, the absorbance value of the interfering solute under ultraviolet light of the second preset wavelength.

[0096] S120. Based on the first preset wavelength, the second preset wavelength, and the second absorbance information, determine the third absorbance information of the interfering solute under ultraviolet light at the first preset wavelength.

[0097] In step S120, the same interfering solute has different absorbance information under ultraviolet light of different preset wavelengths. The third absorbance information of the interfering solute under ultraviolet light of the first preset wavelength can be determined based on the first preset wavelength, the second preset wavelength, and the second absorbance information corresponding to the second preset wavelength.

[0098] S130. Obtain the fourth absorbance information of the solution to be tested under ultraviolet light of the first preset wavelength.

[0099] In step S130, directly detecting the solution to be tested can obtain the fourth absorbance information of the solution under ultraviolet light of the first preset wavelength. The absorbance value corresponding to the fourth absorbance information includes the absorbance value of calcium and magnesium ions and the absorbance value of interfering solutes. It is necessary to remove the absorbance value of interfering solutes according to the absorbance value corresponding to the fourth absorbance information to obtain the absorbance value of calcium and magnesium ions.

[0100] S140. Determine the first absorbance information based on the third absorbance information and the fourth absorbance information.

[0101] In step S140, the absorbance value corresponding to the fourth absorbance information can be removed by removing the absorbance value of the interfering solute corresponding to the third absorbance information, so as to remove the influence of the interfering solute on the absorbance value of calcium and magnesium ions, and obtain the absorbance value of calcium and magnesium ions under ultraviolet light of the first preset wavelength to obtain the first absorbance information.

[0102] In this embodiment, the third absorbance information can be determined by acquiring the second absorbance information. That is, the absorbance value of the interfering solute under ultraviolet light at the first preset wavelength is determined by the absorbance value of the interfering solute under ultraviolet light at the second preset wavelength. After acquiring the fourth absorbance information, that is, directly detecting the absorbance value of the solution to be tested, the first absorbance information is determined based on the third and fourth absorbance information. This realizes the acquisition of the first absorbance information, eliminates the influence of the interfering solute on the absorbance value of calcium and magnesium ions, and thus improves the accuracy of the subsequent calcium and magnesium ion concentration detection results.

[0103] In some embodiments, reference Figure 5 As shown, based on the first preset wavelength, the second preset wavelength, and the second absorbance information, the third absorbance information of the interfering solute under ultraviolet light at the first preset wavelength is determined, including:

[0104] S121. Determine the second preset configuration information. The second preset configuration information is used to characterize the conversion relationship of absorbance information of interfering solute under ultraviolet light of different wavelengths.

[0105] In step S121, the same interfering solute exhibits different absorbance information under ultraviolet light of different preset wavelengths, and there is a specific conversion relationship between the different absorbance information. The second preset configuration information is used to characterize this conversion relationship. For example, the different absorbance information of the same interfering solute under ultraviolet light of different wavelengths includes different absorbance values. The second preset configuration information may include a conversion coefficient between different absorbance values ​​of the interfering solute under ultraviolet light of different wavelengths. For instance, the absorbance value of an organic compound under ultraviolet light at a wavelength of 254 nm is 1.52 times that under ultraviolet light at a wavelength of 320 nm.

[0106] S122. Based on the first preset wavelength, the second preset wavelength, the second absorbance information, and the second preset configuration information, determine the third absorbance information.

[0107] In step S122, after determining the second preset configuration information, the third absorbance information can be determined based on the first preset wavelength, the second preset wavelength, the second absorbance information, and the second preset configuration information. That is, the absorbance value of the interfering solute under the first preset wavelength of ultraviolet light can be determined based on the absorbance value of the interfering solute under the second preset wavelength of ultraviolet light, the first preset wavelength, the second preset wavelength, and the conversion coefficient between different absorbance values ​​of the interfering solute under different wavelengths of ultraviolet light.

[0108] For example, the conversion coefficient of the interfering solute at different absorbance values ​​under the first and second preset wavelengths can be multiplied by the absorbance value corresponding to the second absorbance information, and the product can be determined as the absorbance value corresponding to the third absorbance information. For instance, after determining the conversion coefficient to be 1.52, the absorbance value of the organic compound under 320nm ultraviolet light can be multiplied by 1.52, and the calculation result can be determined as the absorbance value of the organic compound under 254nm ultraviolet light, thus determining the third absorbance information.

[0109] In this embodiment, by determining the second preset configuration information, namely the conversion coefficient between different absorbance values ​​of the interfering solute under different wavelengths of ultraviolet light, the absorbance value of the interfering solute under the first preset wavelength of ultraviolet light can be determined based on the absorbance value of the interfering solute under the second preset wavelength of ultraviolet light, the first preset wavelength, the second preset wavelength, and the conversion coefficient between different absorbance values ​​of the interfering solute under different wavelengths of ultraviolet light. This achieves the acquisition of the third absorbance information, which can eliminate the influence of the interfering solute on the absorbance value of calcium and magnesium ions in the subsequent process, thereby improving the accuracy of the calcium and magnesium ion concentration detection results.

[0110] In some embodiments, reference Figure 6 As shown, the second absorbance information of the interfering solute in the solution to be tested under ultraviolet light of a second preset wavelength is obtained, including:

[0111] S111. Obtain the fifth absorbance information of the solution to be tested under ultraviolet light at the second preset wavelength.

[0112] In step S111, directly detecting the solution to be tested can obtain the fifth absorbance information of the solution under ultraviolet light at the second preset wavelength. The absorbance value corresponding to the fifth absorbance information includes the absorbance value of pure water and the absorbance value of the interfering solute. It is necessary to remove the absorbance value of pure water according to the absorbance value corresponding to the fifth absorbance information to obtain the absorbance value of the interfering solute.

[0113] S112. Obtain the sixth absorbance information of pure water under ultraviolet light of the second preset wavelength;

[0114] S113. Determine the second absorbance information based on the fifth absorbance information and the sixth absorbance information.

[0115] In steps S112 to S113, directly detecting pure water can obtain the sixth absorbance information of pure water under ultraviolet light at the second preset wavelength, that is, the absorbance value of pure water under ultraviolet light at the second preset wavelength. The absorbance value of pure water corresponding to the fifth absorbance information and the absorbance value of interfering solute can be removed by subtracting the absorbance value of pure water corresponding to the sixth absorbance information. The absorbance difference is used as the absorbance value corresponding to the second absorbance information to remove the influence of pure water on the absorbance value of interfering solute, and the absorbance value of interfering solute under ultraviolet light at the second preset wavelength is obtained to realize the acquisition of the second absorbance information.

[0116] In this embodiment, by acquiring the fifth absorbance information of the test solution under ultraviolet light at a second preset wavelength and the sixth absorbance information of pure water under ultraviolet light at a second preset wavelength, that is, the overall absorbance value of pure water and interfering solute under ultraviolet light at a second preset wavelength and the absorbance value of the interfering solute alone, the absorbance value of pure water corresponding to the fifth absorbance information and the interfering solute can be removed by subtracting the absorbance value of pure water corresponding to the sixth absorbance information, thereby realizing the acquisition of the second absorbance information, eliminating the influence of pure water on the absorbance value of the interfering solute, and thus improving the accuracy of the subsequent calcium and magnesium ion concentration detection results.

[0117] In some embodiments, reference Figure 7 As shown, based on the third and fourth absorbance information, the first absorbance information is determined, including:

[0118] S141. Obtain the seventh absorbance information of pure water under ultraviolet light of the first preset wavelength;

[0119] S142. Determine the first absorbance information based on the fourth absorbance information, the seventh absorbance information, and the third absorbance information.

[0120] In steps S141 and S142, the absorbance value corresponding to the fourth absorbance information includes not only the absorbance values ​​of calcium and magnesium ions and interfering solutes, but also the absorbance value of pure water. Directly detecting pure water can obtain the seventh absorbance information of pure water under ultraviolet light at the first preset wavelength, i.e., the absorbance value of pure water under ultraviolet light at the first preset wavelength. The overall absorbance values ​​of calcium and magnesium ions, pure water, and interfering solutes corresponding to the fourth absorbance information can be reduced by removing the absorbance values ​​of the interfering solutes corresponding to the third absorbance information and the absorbance values ​​of pure water corresponding to the seventh absorbance information. This removes the influence of the interfering solutes and pure water on the absorbance value of calcium and magnesium ions, thus obtaining the absorbance value of calcium and magnesium ions under ultraviolet light at the first preset wavelength, thereby achieving the acquisition of the first absorbance information.

[0121] In this embodiment, by obtaining the seventh absorbance information of pure water under ultraviolet light of the first preset wavelength, i.e., the absorbance value of pure water under ultraviolet light of the first preset wavelength, the overall absorbance value of calcium and magnesium ions, pure water, and interfering solute corresponding to the fourth absorbance information can be removed by removing the absorbance value of the interfering solute corresponding to the third absorbance information and the absorbance value of pure water corresponding to the seventh absorbance information. This eliminates the influence of interfering solute and pure water on the absorbance value of calcium and magnesium ions, ensuring the accuracy of the first absorbance information and thus improving the accuracy of the calcium and magnesium ion concentration detection results.

[0122] In some embodiments, the first preset wavelength is greater than or equal to 208 nm and less than or equal to 245 nm.

[0123] As mentioned earlier, the difference in absorbance values ​​between different concentrations of calcium and magnesium ions in the wavelength range of 200nm to 254nm is more obvious than in other wavelength ranges. However, after actual detection, it was found that when the first preset wavelength is greater than 245nm, only calcium and magnesium ions with a concentration greater than 100mg / L can be identified. Furthermore, when the first preset wavelength is less than 208nm, the insufficient radiation energy of ultraviolet light makes it difficult to obtain the first absorbance information of calcium and magnesium ions. Therefore, the range of the first preset wavelength is further limited to 208nm to 245nm.

[0124] In this embodiment, the range of the first preset wavelength is further limited to 208nm to 245nm, which can not only realize the detection and identification of calcium and magnesium ions with a concentration of less than 100mg / L, but also ensure that the radiation energy of ultraviolet light is sufficient to successfully obtain the first absorbance information of calcium and magnesium ions, thereby further improving the detection accuracy and detection sensitivity.

[0125] In one exemplary embodiment, a detection method is provided for detecting the concentration of calcium and magnesium ions in a solution to be detected, with reference to... Figure 8 As shown, the detection methods include:

The first preset configuration information is used to characterize the correspondence between absorbance information and calcium and magnesium ion concentration.

[0135] In this embodiment, by acquiring the first absorbance information of calcium and magnesium ions in the test solution under ultraviolet light at a first preset wavelength, the concentration of calcium and magnesium ions corresponding to the first absorbance information can be determined based on the first absorbance information and the first preset configuration information used to characterize the correspondence between absorbance information and calcium and magnesium ion concentration, thus realizing the acquisition of the calcium and magnesium ion concentration in the test solution. The determination of the first absorbance information removes the interference of pure water and interfering solutes in the test solution, ensuring the accuracy of the first absorbance information. By limiting the first preset wavelength to greater than or equal to 200 nm and less than or equal to 254 nm, the concentration of calcium and magnesium ions corresponding to the first absorbance information can be accurately obtained based on the characteristic of calcium and magnesium ions absorbing ultraviolet light within this wavelength range, ensuring the accuracy of the calcium and magnesium ion concentration test results and improving detection precision and sensitivity.

[0137] In this embodiment, the acquisition module 10 acquires the first absorbance information of calcium and magnesium ions in the solution to be tested under ultraviolet light of a first preset wavelength. Based on the first absorbance information and the first preset configuration information used to characterize the correspondence between absorbance information and calcium and magnesium ion concentration, the determination module 20 determines the calcium and magnesium ion concentration corresponding to the first absorbance information, thus realizing the acquisition of the calcium and magnesium ion concentration in the solution to be tested. By limiting the first preset wavelength to greater than or equal to 200 nm and less than or equal to 254 nm, the calcium and magnesium ion concentration corresponding to the first absorbance information can be accurately obtained by taking advantage of the characteristic that calcium and magnesium ions absorb ultraviolet light within this wavelength range, ensuring the accuracy of the calcium and magnesium ion concentration test results and improving detection precision and sensitivity.

The inner diameter of the capillary 30 can be, for example, less than or equal to 2 mm. The capillary 30 includes a first end 31 and a second end 32 positioned opposite each other. Using the capillary 30 as a sample cell not only facilitates the detection of flowing samples but also improves detection sensitivity. A light source 40 is located at the first end 31 of the capillary 30 and emits ultraviolet light parallel to the axial direction of the capillary 30. A photodetector 50 receives the detection beam passing through the solution to be tested and generates corresponding absorbance information.

[0144] The controller 90 is communicatively connected to the photodetector 50 and is capable of acquiring absorbance information generated by the photodetector 50.

In other words, the controller executes the detection method described above.

[0145] In this embodiment, a capillary tube, a light source, a photodetector, and a controller can acquire the first absorbance information of calcium and magnesium ions in the solution under ultraviolet light of a first preset wavelength. The controller then determines the calcium and magnesium ion concentration corresponding to the first absorbance information based on the first absorbance information and a first preset configuration, thus achieving the detection of calcium and magnesium ion concentration. By limiting the first preset wavelength to greater than or equal to 200 nm and less than or equal to 254 nm, the characteristic of calcium and magnesium ions absorbing ultraviolet light within this wavelength range can be used to accurately obtain the calcium and magnesium ion concentration corresponding to the first absorbance information, ensuring the accuracy of the calcium and magnesium ion concentration test results and improving detection precision and sensitivity.

In some embodiments, reference... Figure 10 As shown, the wavelength adjustment unit 70 includes a linear gradient filter 71, which is movable between the first lens 60 and the capillary 30.

[0149] The wavelength adjustment unit 70 includes a linear variable filter (LVF) 71, which can move between the first lens 60 and the capillary 30.
