DETAILED DESCRIPTION

[0080] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0081] In recent years, with the rapid development of material composition and material content detection technology, water quality detection and hardness detection have been widely used in geological exploration, sewage treatment and other fields. Calcium ions and magnesium ions are nutrients required by the human body on the one hand, and on the other hand, they are the main causes of scale generation, which causes blockage or damage to equipment pipes. At the same time, the concentration of calcium ions and magnesium ions is also used as a measure of water hardness. Therefore, it is particularly critical to detect the concentration of calcium and magnesium ions in the solution to be tested.

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

[0083] However, when the concentration of calcium and magnesium ions is detected by relevant technologies, the absorption spectra of solutions with different calcium and magnesium ion concentrations under ultraviolet light of the detection wavelength are slightly different. When the concentration of calcium and magnesium ions is low, it is difficult to accurately identify the concentration of calcium and magnesium ions. The detection accuracy and sensitivity are low, which will lead to problems such as the inability to obtain test results or excessive errors in the test results.

[0084] Based on this, the exemplary embodiment of the present disclosure provides a detection device, which can obtain the first absorbance information of calcium and magnesium ions in the solution to be detected under ultraviolet light of the first preset wavelength through a capillary, a light source, a photodetector and a controller, and determine the calcium and magnesium ion concentration corresponding to the first absorbance information according to the first absorbance information and the first preset configuration information through the controller, thereby realizing the detection of the calcium and magnesium ion concentration. The first preset wavelength is limited to greater than or equal to 200nm and less than or equal to 254nm, and the calcium and magnesium ion concentration corresponding to the first absorbance information can be accurately obtained by relying on the characteristics of calcium and magnesium ions absorbing ultraviolet light within this wavelength range, thereby ensuring the accuracy of the calcium and magnesium ion concentration test results and improving the detection accuracy and detection sensitivity.

[0085] In an exemplary embodiment, a detection method is provided for detecting the concentration of calcium and magnesium ions in a solution to be detected, referring to Figure 1 As shown, the detection method includes:

[0086] S100, obtaining first absorbance information of calcium and magnesium ions in a solution to be detected under ultraviolet light of a first preset wavelength, where 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 detected may include, for example, pure water, calcium and magnesium ions and other interfering solutes, and the concentration of calcium and magnesium ions is the overall concentration of calcium ions 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, and the absorbance value is the absorptivity 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 detected under the light source with a spectrophotometer, and converting the output light power into a corresponding absorbance value.

[0088] S200. Determine the calcium and magnesium ion concentrations corresponding to the first absorbance information according to the first absorbance information and the first preset configuration information, wherein the first preset configuration information is used to characterize the corresponding relationship between the absorbance information and the calcium and magnesium ion concentrations.

[0089] In step S200, the first preset configuration information can be represented by, for example, an absorption spectrum curve of calcium and magnesium ions. For example, the absorption spectrum standard curves of calcium and magnesium ions with different concentrations are as follows: Figure 2 and Figure 3 As shown, the horizontal axis in the figure 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 according to the absorbance value of calcium and magnesium ions under ultraviolet light of the first preset wavelength. For example, when the first absorbance information includes that the absorbance value of calcium and magnesium ions under ultraviolet light with a wavelength of 204nm is 1.79%, it can be determined according to the first preset configuration information that the calcium and magnesium ion concentration corresponding to the absorbance information is 1mg / L, and the calcium and magnesium ion concentration can be determined as 1mg / L.

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

[0091] The first preset configuration information, for example, can also be a data set composed of multiple data, each data being a different calcium and magnesium ion concentration value corresponding to a different absorbance value range of calcium and magnesium ions under ultraviolet light of a first preset wavelength. The first absorbance information of calcium and magnesium ions under ultraviolet light of a first preset wavelength can be determined based on the calcium and magnesium ion concentration value corresponding to the absorbance value in the data set to determine the corresponding calcium and magnesium ion concentration.

[0092] In this embodiment, by obtaining the first absorbance information of calcium and magnesium ions in the solution to be detected under ultraviolet light of the first preset wavelength, the calcium and magnesium ion concentration corresponding to the first absorbance information can be determined according to the first absorbance information and the first preset configuration information used to characterize the correspondence between the absorbance information and the calcium and magnesium ion concentration, thereby achieving the acquisition of the calcium and magnesium ion concentration in the solution to be detected. By limiting the first preset wavelength to be greater than or equal to 200nm and less than or equal to 254nm, the calcium and magnesium ion concentration corresponding to the first absorbance information can be accurately obtained by relying on the significant difference in different absorbance values ​​corresponding to different concentrations of calcium and magnesium ions within the wavelength range, thereby ensuring the accuracy of the calcium and magnesium ion concentration test results and improving the detection accuracy and detection sensitivity.

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

[0094] S110, obtaining second absorbance information of the interfering solute in the solution to be detected under ultraviolet light of a second preset wavelength, wherein the interfering solute can absorb ultraviolet light under the ultraviolet light of the second preset wavelength, 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 detected may include, for example, the total organic carbon (TOC) in water. Under the ultraviolet light of the second preset wavelength, the interfering solute can absorb ultraviolet light, that is, the interfering solute has an absorbance value, and the absorbance value of calcium and magnesium ions is less than or equal to the absorbance threshold value, and the absorbance threshold value may be, for example, 0. When the absorbance value of calcium and magnesium ions is less than the absorbance threshold value, the absorbance value of calcium and magnesium ions can be ignored for the absorbance value of the solution to be detected. At this time, the solution to be detected is detected, and the second absorbance information of the interfering solute in the solution to be detected under the ultraviolet light of the second preset wavelength can be obtained. The second absorbance information may include, for example, the absorbance value of the interfering solute under the ultraviolet light of the second preset wavelength.

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

[0097] In step S120, the same interfering solute has different absorbance information under ultraviolet light of different preset wavelengths, and 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, obtaining fourth absorbance information of the solution to be detected under ultraviolet light of a first preset wavelength.

[0099] In step S130, directly testing the solution to be detected can obtain the fourth absorbance information of the solution to be detected under ultraviolet light of the first preset wavelength. At this time, 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 the interfering solute according to the absorbance value corresponding to the fourth absorbance information to obtain the absorbance value of calcium and magnesium ions.

[0100] S140: Determine first absorbance information according to the third absorbance information and the fourth absorbance information.

[0101] In step S140, the absorbance value corresponding to the fourth absorbance information can be divided by the absorbance value of the interfering solute corresponding to the third absorbance information to remove the influence of the interfering solute on the absorbance value of calcium and magnesium ions, and the absorbance value of calcium and magnesium ions under ultraviolet light of the first preset wavelength can be obtained to achieve the acquisition of 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 corresponding to the interfering solute under ultraviolet light of the first preset wavelength is determined by the absorbance value of the interfering solute under ultraviolet light of the second preset wavelength, and after obtaining the fourth absorbance information, that is, directly detecting the absorbance value of the solution to be detected, the first absorbance information is determined according to the third absorbance information and the fourth absorbance information, thereby realizing the acquisition of the first absorbance information, eliminating the influence of the interfering solute on the absorbance value of calcium and magnesium ions, and thereby improving the accuracy of 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, determining the third absorbance information of the interfering solute under the ultraviolet light of the first preset wavelength includes:

[0104] S121. Determine second preset configuration information, where the second preset configuration information is used to characterize a conversion relationship between absorbance information of interfering solutes under ultraviolet light of different wavelengths.

[0105] In step S121, the same interfering solute has different absorbance information under ultraviolet light of different preset wavelengths, and there is a specific conversion relationship between the different absorbance information, and the second preset configuration information is used to characterize the conversion relationship. Exemplarily, the different absorbance information of the same interfering solute under ultraviolet light of different wavelengths includes different absorbance values, and 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 example, the absorbance value of organic matter under ultraviolet light of 254nm wavelength is 1.52 times the absorbance value under ultraviolet light of 320nm wavelength.

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

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

[0108] For example, the conversion coefficient of the different absorbance values ​​of the interfering solute at the first preset wavelength and the second preset wavelength 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 example, after determining that the conversion coefficient is 1.52, the absorbance value of the organic matter under ultraviolet light with a wavelength of 320nm can be multiplied by 1.52, and the calculation result can be determined as the absorbance value of the organic matter under ultraviolet light with a wavelength of 254nm, so as to achieve the determination of the third absorbance information.

[0109] In this embodiment, by determining the second preset configuration information, that is, the conversion coefficient between different absorbance values ​​of the interfering solute under ultraviolet light of different wavelengths, the absorbance value of the interfering solute under ultraviolet light of the first preset wavelength can be determined according to the absorbance value of the interfering solute under ultraviolet light of the second preset wavelength, the first preset wavelength, the second preset wavelength, and the conversion coefficient between different absorbance values ​​of the interfering solute under ultraviolet light of different wavelengths, thereby realizing the acquisition of the third absorbance information, and being able to subsequently eliminate the influence of the interfering solute on the absorbance value of calcium and magnesium ions, thereby improving the accuracy of the calcium and magnesium ion concentration detection results.

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

[0111] S111, obtaining fifth absorbance information of the solution to be detected under ultraviolet light of a second preset wavelength.

[0112] In step S111, the fifth absorbance information of the solution to be detected under ultraviolet light of a second preset wavelength can be obtained by directly detecting the solution to be detected. At this time, the absorbance value corresponding to the fifth absorbance information includes the absorbance value of pure water and the absorbance value of the interfering solute. The absorbance value of pure water needs to be removed according to the absorbance value corresponding to the fifth absorbance information to obtain the absorbance value of the interfering solute.

[0113] S112, obtaining sixth absorbance information of pure water under ultraviolet light of a second preset wavelength;

[0114] S113. Determine second absorbance information according to the fifth absorbance information and the sixth absorbance information.

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

[0116] In this embodiment, by obtaining the fifth absorbance information of the solution to be detected under ultraviolet light of the second preset wavelength and the sixth absorbance information of pure water under ultraviolet light of the second preset wavelength, that is, the overall absorbance value of pure water and interfering solutes and the absorbance value of the interfering solute alone under ultraviolet light of the second preset wavelength, the absorbance value of pure water and interfering solute corresponding to the fifth absorbance information can be removed by subtracting the absorbance value of pure water corresponding to the sixth absorbance information, so as to achieve the acquisition of the second absorbance information, eliminate the influence of pure water on the absorbance value of interfering solutes, and thereby improve the accuracy of subsequent calcium and magnesium ion concentration detection results.

[0117] In some embodiments, reference Figure 7 As shown, determining the first absorbance information according to the third absorbance information and the fourth absorbance information includes:

[0118] S141, obtaining seventh absorbance information of pure water under ultraviolet light of a first preset wavelength;

[0119] S142. Determine first absorbance information according to the fourth absorbance information, the seventh absorbance information, and the third absorbance information.

[0120] In step S141 to step S142, the absorbance value corresponding to the fourth absorbance information includes the absorbance value of pure water in addition to the absorbance value of calcium and magnesium ions and the absorbance value of interfering solutes. Directly detecting pure water can obtain the seventh absorbance information of pure water under ultraviolet light of the first preset wavelength, that is, 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 solutes 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, so as to remove the influence of interfering solutes and pure water 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 achieve 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, that is, 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 solutes 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, thereby eliminating the influence of interfering solutes and pure water on the absorbance value of calcium and magnesium ions, ensuring the accuracy of the first absorbance information, and thereby improving the accuracy of the calcium and magnesium ion concentration detection results.

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

[0123] As mentioned above, the difference between the absorbance values ​​of 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, and when the first preset wavelength is less than 208nm, the insufficient radiation energy of the ultraviolet light will also make 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 less than 100mg / L, but also ensure that the radiation energy of ultraviolet light is sufficient to smoothly obtain the first absorbance information of calcium and magnesium ions, thereby further improving the detection accuracy and sensitivity.

In the process of determining the first absorbance information, the interference of pure water and interfering solutes on calcium and magnesium ions in the solution to be detected is eliminated, thereby ensuring the accuracy of the first absorbance information. By limiting the first preset wavelength to greater than or equal to 200nm and less than or equal to 254nm, the concentration of calcium and magnesium ions corresponding to the first absorbance information can be accurately obtained by relying on the characteristic of calcium and magnesium ions absorbing ultraviolet light within this wavelength range, thereby ensuring the accuracy of the calcium and magnesium ion concentration test results and improving the detection accuracy and detection sensitivity.
