[0050] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0051] The organic matter spectral detection method provided by the embodiments of the present application can be applied to, for example, Figure 1The application environment is shown. Among them, the spectrometer 102 communicates with the server 104 through the network. The data storage system can store the data required by the server 104 to process. The data storage system can be integrated on the server 104, or placed on the cloud or other network servers. Specifically, the spectrometer 102 respectively performs spectral scanning on the reference solution and the test solution in the solution pair to obtain the first spectrum of the reference solution and the second spectrum of the test solution; wherein the test solution is obtained by adding the organic matter to be tested to the reference solution; and the obtained first spectrum and second spectrum are transmitted to the server 104, and the server 104 determines the spectral characteristics of the organic matter to be tested according to the first spectrum and the second spectrum. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0052] In one embodiment, as shown in Figure 2 , an organic matter spectrum detection method is provided, which is applied to the server in Figure 1 , as shown in Figure 2 , comprising the following steps:

[0053] Step 202, respectively performing spectral scanning on the reference solution and the test solution in the solution pair to obtain the first spectrum of the reference solution and the second spectrum of the test solution;

[0054] Among them, the solution pair can be a solution group composed of the reference solution and the test solution.

[0055] The reference solution can be a blank extraction solution or a solution in which other organic matters are added to the extraction solution. The test solution is obtained by adding the organic matter to be tested to the reference solution. Exemplarily, the extraction solution of the present embodiment can be n-hexane.

[0056] The spectrum is an image obtained by the spectral detection device performing spectral scanning on the substance.

[0057] The first spectrum is the spectrum obtained by performing spectral scanning on the reference solution.

[0058] The second spectrum is the spectrum obtained by performing spectral scanning on the test solution.

[0059] Optionally, when the server has a spectral detection requirement, the present embodiment can call the spectrometer to respectively perform spectral scanning on the reference solution and the test solution in the solution pair to obtain the first spectrum of the reference solution and the second spectrum of the test solution. Specifically, a spectral scanning instruction can be sent to the spectrometer, and after receiving the instruction, the spectrometer will start spectral scanning on the reference solution and the test solution to obtain the first spectrum of the reference solution and the second spectrum of the test solution, and feed back the obtained first spectrum and second spectrum to the server, at which time the server can obtain the first spectrum and the second spectrum.

[0060] Optionally, in order to ensure the accuracy of the spectral scanning result, before the spectral scanning, the cleaning of the vessel and the zero setting of the spectrometer are required, and the cleaning method is as follows:

[0061] Before scanning, the vessel containing the scanning solution is cleaned twice with the cleaning agent, and after being dried, the sample test is performed after being rinsed with the scanning solution. The scanning solution includes the reference solution and the test solution.

[0062] If the reference solution and the test solution are contained in the same vessel, after the test of one scanning solution is completed, before the other scanning solution is replaced, the vessel needs to be cleaned more than twice with the cleaning agent, and after being dried, the other scanning solution needs to be used for rinsing, and the spectral zero setting of the vessel is performed again to ensure the cleaning effect.

[0063] The cleaning agent is hexane, but is not limited to hexane; the vessel is used to contain the reference solution and the test solution during scanning, and when the reference solution is scanned, the vessel is used to contain the reference solution, and when the test solution is scanned, the vessel is used to contain the test solution. The vessel is a cuvette, but is not limited to a cuvette.

[0064] The method for zero setting of the spectrometer includes:

[0065] The zero setting of the ultraviolet-visible spectrometer is performed using the reagent-free vessel.

[0066] In step 204, the spectral characteristics of the to-be-tested organic matter are determined according to the first spectrum and the second spectrum.

[0067] Optionally, one implementation manner of determining the spectral characteristics of the to-be-tested organic matter according to the first spectrum and the second spectrum is that the first spectrum and the second spectrum are input into a pre-trained spectral characteristic extraction model, the spectral characteristic extraction model automatically analyzes the difference between the two input spectra, and outputs the spectral characteristics of the to-be-tested organic matter based on the analysis result.

[0068] Another implementation manner is that the spectral characteristics of the to-be-tested organic matter are obtained by comparing the waveform differences of the first spectrum and the second spectrum. Specifically, the waveform characteristics of the first spectrum and the second spectrum are extracted respectively, and the waveform characteristics of the two extracted spectra are compared, and the waveform characteristic difference of the two spectra is taken as the spectral characteristics of the to-be-tested organic matter.

[0069] In the above organic matter spectrum detection method, the first spectrum graph is obtained by spectrum scanning on the reference solution, the test solution is obtained by adding the organic matter to be detected into the reference solution, and the second spectrum graph is obtained by spectrum scanning on the test solution. The spectrum characteristics of the organic matter to be detected can be obtained by comparing the first spectrum graph and the second spectrum graph. The spectrum characteristics of the organic matter to be detected are determined by analyzing the spectrum graphs of the reference solution and the test solution, which solves the problem that the spectrum characteristics of the organic matter to be detected mixed in the solution cannot be accurately detected in the prior art, thereby realizing spectrum detection of the organic compound mixed in the solution (such as an extraction solution). The spectrum detection of the organic compound mixed in the solution (such as an extraction solution) is simple, accurate and efficient.

[0070] The present application can be applied to spectrum detection of organic matter, especially detection of organic toxicants, and can measure the spectrum characteristics of most typical organic toxicants.

[0071] In one embodiment, step 202 can further include:

[0072] The reference solution and the test solution in the solution pair are respectively scanned by the ultraviolet-visible spectrometer.

[0073] Optionally, when scanning, the ultraviolet-visible spectrometer is set to have a wavelength range of 190nm-1100nm and a spectrum wideband range of 0.1-10nm; wherein, when spectrum scanning is performed, the spectrum wideband is preferably set to 1nm.

[0074] In this embodiment, most organic matter can absorb certain ultraviolet-visible light, so the ultraviolet-visible spectrometer can be used to detect the spectrum of most organic matter, which has a wider application range and is particularly valuable for the detection of organic toxicants.

[0075] In one embodiment, one implementation of step 204 can be to compare the waveform difference between the first spectrum graph and the second spectrum graph, and take the waveform difference between the two spectrum graphs as the spectrum characteristics of the organic matter to be detected. For example, the spectrum peak difference and / or spectrum valley difference between the first spectrum graph and the second spectrum graph can be compared, and the waveform difference between the two spectrum graphs can be taken as the spectrum characteristics of the organic matter to be detected.

[0076] Based on the above embodiment, in order to improve the comparison efficiency of the first spectrum graph and the second spectrum graph, as shown in Figure 3 An optional embodiment for comparing the waveform difference between the first spectrum graph and the second spectrum graph to obtain the spectrum characteristics of the organic matter to be detected is given, which can include the following steps:

[0077] Step 301: determining the waveform characteristic type to be compared according to the type of the organic matter to be detected and / or the composition of the reference solution.

[0078] The waveform feature type includes, but is not limited to, a feature spectral line and a spectral peak.

[0079] Optionally, in the embodiment, if the type of the to-be-tested organic matter is known, then the waveform feature type to be compared can be determined according to the type of the to-be-tested organic matter. If the composition of the reference solution is known, then the waveform feature type to be compared can be determined according to the composition of the reference solution. If both the type of the to-be-tested organic matter and the composition of the reference solution are known, then the waveform feature type to be compared can be determined according to the type of the to-be-tested organic matter and the composition of the reference solution.

[0080] Specifically, the correspondence between different types of to-be-tested organic matters and the waveform feature type to be compared, and the correspondence between different compositions of reference solutions and the waveform feature type to be compared can be preset according to the relationship between the type of the to-be-tested organic matter and the composition of the reference solution and the spectral waveform. Then, the waveform feature type to be compared can be determined according to the preset relationship, in combination with the type of the to-be-tested organic matter and / or the composition of the reference solution.

[0081] For example, diisodecyl phthalate has a characteristic absorption peak at a wavelength of 282 nm, and the absorbance is 0.193 L / (g·cm). Therefore, the waveform feature type to be compared corresponding to diisodecyl phthalate can be preset as a spectral peak. If it is known that the to-be-tested organic matter is diisodecyl phthalate, but the composition of the reference solution is unknown, then the waveform feature type to be compared can be determined as a spectral peak.

[0082] Optionally, if the waveform feature type to be compared determined according to the type of the to-be-tested organic matter is different from the waveform feature type to be compared determined according to the composition of the reference solution, then the two determined waveform feature types can be used as the final waveform feature type to be compared, or one of the two waveform feature types can be selected as the final waveform feature type to be compared according to the priority between the type of the to-be-tested organic matter and the composition of the reference solution.

[0083] In step 302, the first spectral graph and the second spectral graph are subjected to waveform difference comparison according to the waveform feature type, to obtain the spectral feature of the to-be-tested organic matter.

[0084] In the embodiment, the waveform feature type to be compared is first determined according to the known type of the to-be-tested organic matter and / or the composition of the reference solution, and then the first spectral graph and the second spectral graph are subjected to targeted waveform difference comparison based on the waveform feature type, which can effectively improve the efficiency and accuracy of the waveform difference comparison of the first spectral graph and the second spectral graph.

[0085] Optionally, in the case of multiple organic substances to be detected, multiple sets of solution pairs are required for the spectral detection of the organic substances, such as Figure 4 As shown in the figure, the organic substance spectral detection method at this time comprises the following steps:

[0086] Step 401: Two solutions in which only one different organic substance to be detected exists in the original extraction solution and at least one mixed extraction solution are taken as a set of solution pairs; at least one organic substance to be detected is added to each mixed extraction solution.

[0087] The original extraction solution can be a blank extraction solvent, such as n-hexane, or a mixed solution of an extraction solvent and one or more organic substances to be detected, such as a mixed solution of n-hexane and diisodecyl phthalate (i.e., one of the multiple organic substances to be detected).

[0088] The mixed extraction solution is an original extraction solution to which at least one organic substance to be detected is added.

[0089] Optionally, in the case of determining the solution pairs for spectral detection according to the original extraction solution and at least one mixed extraction solution, the mixed extraction solution to which one more organic substance to be detected is added than the original extraction solution is selected as the solution pair for the original extraction solution, and the original extraction solution and each selected mixed extraction solution are combined to obtain a set of solution pairs. That is, the solution pair at this time contains the original extraction solution and a mixed extraction solution selected based on the original solution.

[0090] In the case of selecting the solution pair for each mixed extraction solution, a solution to which one more organic substance to be detected is added than the mixed extraction solution is selected, and each selected mixed extraction solution is combined to obtain a set of solution pairs. That is, the solution pair at this time contains the mixed extraction solution and another mixed extraction solution selected based on the mixed extraction solution.

[0091] Step 402: According to the types of organic substances to be detected added to the two solutions in each set of solution pairs, the reference solution and the test solution in the set of solution pairs are determined.

[0092] Optionally, the embodiment can analyze the types of organic substances to be detected added to the two solutions in each set of solution pairs, and take the solution in which more types of organic substances to be detected are added as the test solution and the solution in which fewer types of organic substances to be detected are added as the reference solution.

[0093] It should be noted that, in addition to the above-mentioned steps 401 and 402, the solution pairs can also be determined from the original extraction solution and at least one mixed extraction solution by manual selection.

[0094] In step 403, the reference solution and the test solution in each solution pair are respectively scanned to obtain the first spectrum of the reference solution and the second spectrum of the test solution in each solution pair.

[0095] The test solution is obtained by adding the to-be-detected organic matter to the reference solution.

[0096] In step 404, the spectral characteristics of the to-be-detected organic matter are determined according to the first spectrum and the second spectrum in each solution pair.

[0097] The application based on the selection strategy of the above solution pair has a more flexible range of use and effectively improves the intelligent degree of spectral detection of the organic matter.

[0098] In one embodiment, after the spectral characteristics of the to-be-detected organic matter are determined, the method further includes:

[0099] Based on the spectral characteristics, the attribute information of the to-be-detected organic matter is determined.

[0100] The attribute information at least includes the name information of the to-be-detected organic matter.

[0101] Optionally, the embodiment can pre-set a database recording the attribute information and the spectral characteristics of various organic matters, at this time, the spectral characteristics of the to-be-detected organic matter can be matched with the spectral characteristics recorded in the database, if the matching degree meets the set condition, the attribute information corresponding to the matched spectral characteristics in the database can be taken as the attribute information of the to-be-detected organic matter. The calculation method of the matching degree includes but is not limited to the coincidence degree of the spectral curve, the coincidence degree of the spectral peak, the wavelength and the light absorption degree.

[0102] The embodiment solves the key technical problem that the organic matter (such as organic toxicant) can be automatically and quickly determined qualitatively and quantitatively (i.e. the attribute information is determined) during or after the extraction process, and provides a basis for the automatic and intelligent technology and equipment research and development of organic matter detection and analysis.

[0103] Optionally, on the basis of the above embodiment, as shown in the following Figure 5 The embodiment provides an optional way of spectral detection of multiple organic matters, including the following steps:

[0104] In step 501, two solutions in which only one different to-be-detected organic matter exists in the original extraction solution and at least one mixed extraction solution are taken as a solution pair; at least one to-be-detected organic matter is added to each mixed extraction solution.

[0105] In step 502, the reference solution and the test solution in the solution pair are determined according to the types of the to-be-detected organic matter in the two solutions in each solution pair.

[0106] Step 503, for each solution pair, using an ultraviolet-visible spectrometer, respectively scanning the reference solution and the test solution in each solution pair to obtain the first spectrum of the reference solution and the second spectrum of the test solution in each solution pair.

[0107] Step 504, according to the type of the organic matter to be detected and / or the composition of the reference solution, determining the waveform feature type to be compared;

[0108] Step 505, according to the waveform feature type, comparing the waveform difference between the first spectrum and the second spectrum in each solution pair to obtain the spectral feature of the organic matter to be detected.

[0109] Step 506, based on the spectral feature, determining the attribute information of the organic matter to be detected; wherein the attribute information at least includes the name information of the organic matter to be detected.

[0110] For example, next, with n-hexane and soil matrix as the main components of the original extraction solution, and diisodecyl phthalate and hexabromocyclododecane as the organic matter to be detected, the spectral detection process of the organic matter is introduced.

[0111] (I) In this embodiment, there are two original extraction solutions, wherein the original extraction solution 1 is 10 mL of n-hexane, and the original extraction solution 2 is a mixture of soil matrix and 20 mL of n-hexane. In this embodiment, there are three mixed extraction solutions, wherein the mixed extraction solution 1 is a solution of diisodecyl phthalate with a concentration of 50 ppm obtained by adding a certain amount of diisodecyl phthalate to n-hexane solvent, the mixed extraction solution 2 is a solution of hexabromocyclododecane with a concentration of 50 ppm obtained by adding a certain amount of hexabromocyclododecane to n-hexane solvent, and the mixed extraction solution 3 is a mixed solution obtained by adding soil matrix to the mixed extraction solution 1. Then, the original extraction solution 1 and the mixed extraction solution 1 are taken as the first solution pair; the original extraction solution 1 and the mixed extraction solution 2 are taken as the second solution pair; and the original extraction solution 2 and the mixed extraction solution 3 are taken as the third solution pair.

[0112] (II) Turn on the ultraviolet-visible spectrometer and initialize it, set the wavelength range to 190-1100 nm and the spectral bandwidth to 1 nm. Wash the cuvette that needs to carry the solution in the solution pair with n-hexane twice, dry it, and then use the empty cuvette to zero the ultraviolet-visible spectrometer. After zeroing, test the spectrum of the empty cuvette. If no absorbance appears, the zeroing is successful.

[0113] (Three), the cleaned cuvette is used to hold the original extraction solution 1 (i.e. the reference solution in the first group of solution pairs), and the original extraction solution 1 held in the cuvette is tested by the ultraviolet-visible spectrometer after zero adjustment, to obtain a curve graph of the wavelength corresponding to the original extraction solution 1 and the corresponding absorbance, i.e. a spectrum curve graph, as shown in Figure 6A . The original extraction solution 1 has five characteristic spectrum peaks at wavelengths of 745 nm, 760 nm, 913 nm, 928 nm and 1020 nm, and the absorbance is -0.0017 L / (g·cm), -0.0017 L / (g·cm), 0.117 L / (g·cm), 0.107 L / (g·cm) and 0.045 L / (g·cm) respectively.

[0114] (Four), the cleaned cuvette is used to hold the mixed extraction solution 1, and the mixed extraction solution 1 held in the cuvette is tested by the ultraviolet-visible spectrometer after zero adjustment, to obtain a curve graph of the wavelength corresponding to the mixed extraction solution 1 and the corresponding absorbance, i.e. a spectrum curve graph, as shown in Figure 6B . The mixed extraction solution 1 has one characteristic absorption peak at a wavelength of 282 nm, and the absorbance is 0.193 L / (g·cm), indicating that the concentration of 50 ppm of diisodecyl phthalate (DIDP) has one obvious characteristic peak in the ultraviolet-visible spectrometer. The waveform difference between the two spectrum curve graphs shown in Figure 6A and Figure 6B is taken as the spectrum characteristic of diisodecyl phthalate (DIDP).

[0115] (Five), the cleaned cuvette is used to hold the mixed extraction solution 2 (i.e. the test solution in the second group of solution pairs), and the mixed extraction solution 2 held in the cuvette is tested by the ultraviolet-visible spectrometer after zero adjustment, to obtain a curve graph of the wavelength corresponding to the mixed extraction solution 2 and the corresponding absorbance, i.e. a spectrum curve graph, as shown in Figure 6C . The mixed extraction solution 2 has two characteristic absorption peaks at wavelengths of 300 nm and 309 nm, and the absorbance is 2.817 L / (g·cm) and 2.895 L / (g·cm) respectively, indicating that the concentration of 50 ppm of hexabromocyclododecane has two obvious characteristic peaks in the ultraviolet-visible spectrometer. The waveform difference between the two spectrum curve graphs shown in Figure 6A and Figure 6C is taken as the spectrum characteristic of hexabromocyclododecane.

[0116] (Six), the cleaned cuvette is used to take 10 mL of the original extraction solution 2 (i.e. the reference solution in the third group of solution pairs) and 10 mL of the mixed extraction solution 3 (i.e. the test solution in the third group of solution pairs), and the spectrum scanning is performed respectively, and the obtained spectrum graphs are as shown in Figure 6D and Figure 6EAs shown, the spectral graph of diisodecyl phthalate can be obtained by comparing the spectral graph of the original extraction solution 2 ( Figure 6D ) and the spectral graph of the mixed extraction solution 3 ( Figure 6E ), which is consistent with the spectral characteristics of diisodecyl phthalate obtained by comparing the first group of solutions, and further verifies the feasibility and accuracy of the method.

[0117] Alternatively, the configuration process of the original extraction solution 2 and the mixed extraction solution 3 in the embodiment is as follows: the collected soil is air-dried and ground to 100 mesh as the extraction matrix, and 5g (accurate to 0.001g) of soil sample is accurately weighed and added into a 30mL glass centrifuge tube; 20mL of mixed extraction solution 1 is added into one glass centrifuge tube containing the soil sample as the preliminary mixed solution of the mixed extraction solution 3, and 20mL of n-hexane is added into another glass centrifuge tube containing the soil sample as the preliminary mixed solution of the original extraction solution 2. After the preliminary mixed solution of the mixed extraction solution 3 and the preliminary mixed solution of the original extraction solution 2 are sequentially subjected to vortex, ultrasonic and centrifugal treatment, 0.45μm organic phase filter membrane is used for filtration to obtain the mixed extraction solution 3 and the original extraction solution 2.

[0118] Optionally, the vortex treatment time is 30s, the ultrasonic treatment time is 30min, and the centrifugal treatment is centrifuged at a speed of 3500rpm for 4min.

[0119] It should be understood that although each step in the flowchart involved in each embodiment as described above is displayed in sequence according to the direction of the arrow, these steps are not necessarily executed in sequence according to the direction of the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, at least part of the steps in the flowchart involved in each embodiment as described above can include multiple steps or stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least part of other steps or steps or stages in other steps.
