(First embodiment)
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating a functional configuration example of the component analysis evaluation apparatus according to the present embodiment. In the present embodiment, an example in which the present apparatus is installed in a water sampling facility installed in a river, a lake, or the like will be described.

  In FIG. 1, reference numeral 101 denotes a water sampling device, which is a device for sampling sample water directly from rivers, lakes and the like. The water sampling device 101 includes a container for storing the sample water collected, and a signal indicating that reanalysis is performed is sent from a data determination unit 105 described later via a component analysis unit 102 described later. In this case, the water sampling device 101 drains the sample water filled in the container, and samples the sample water again from a river, a lake, or the like. When a plurality of containers for storing sample water are provided and a signal indicating that reanalysis is performed is sent from the data discriminating unit 105, the sample water is collected again in another container without draining the sample water. You may make it do.

  Reference numeral 102 denotes a component analysis unit that performs quantitative analysis on ion components contained in the sample water sampled by the water sampling apparatus 101. As an analysis method, analysis is performed with an analyzer such as an ion chromatograph.

  Reference numeral 103 denotes an EC measurement unit that measures the electrical conductivity of the sample water sampled by the water sampling apparatus 101. As a measurement method, measurement is performed with an apparatus such as an EC meter.

A data processing unit 104 aggregates the analysis values of the components analyzed by the component analysis unit 102, and calculates electrical conductivity based on the aggregation results. The relationship between electrical conductivity and dissolved ion equivalent has already been systematically theorized by Kohlrausch (1897), Onsager (1927) and others, but the inventor of the present application is concerned with terrestrial water such as lake water and river water. The simple cation equivalent or anion equivalent per unit volume of sample water containing an amount of dissolved ions exceeding 10 mS m ^-1 that could not be calculated by the theoretical formula We found a high correlation between the sum and the electrical conductivity. Therefore, in the present embodiment, the electrical conductivity (EC) is calculated using the equation shown in the following formula 1 in which the relationship between the electrical conductivity and the total cation sum and the total anion sum is calculated by the least square method.

The main cations of surface water such as river water and lake water are usually sodium ion (Na ⁺ ), potassium ion (K ⁺ ), magnesium ion (Mg ²⁺ ) as shown in ^{Equation 1} . There are four types of calcium ions (Ca ²⁺ ), but rarely those with extremely low pH (pH is 4 or less) and reductive groundwater are hydrogen ions (H ⁺ ) and ammonium ions (NH ₄ ⁺ ). Is significantly present.

Similarly, as shown in Equation 1, the major anions are usually chloride ions (Cl ⁻ ), nitrate ions (NO ₃ ⁻ ), sulfate ions (SO ₄ ²⁻ ), bicarbonate ions (HCO). ₃ ^-) is a four, depending geological fluoride ion (F ^-), ₄ ^3- phosphate ion (PO artificial load may large in), when the pH is high (pH of 9 or more), the carbonate ion (CO ₃ ²⁻ ) and hydroxide ions (OH ⁻ ) are significantly present.

  Therefore, in the formula of Equation 1, the cation is represented by the sum of four kinds of sodium ion, potassium ion, magnesium ion, and calcium ion. However, depending on the case, the electric conductivity including hydrogen ion and ammonium ion is shown. calculate. Similarly, regarding anions, in addition to the four types of chloride ions, nitrate ions, sulfate ions, and bicarbonate ions, in some cases, fluoride ions, phosphate ions, carbonate ions, or hydroxide ions are included. To calculate the electrical conductivity.

  The data processing unit 104 includes a memory (not shown), and temporarily stores the analysis value of the component analyzed by the component analysis unit 102 and the electrical conductivity measured by the EC measurement unit 103 in the memory. To do.

  A data discriminating unit 105 compares the electrical conductivity calculated by the data processing unit 104 with the electrical conductivity measured by the EC measuring unit 103, and the reliability of the analysis result in the component analyzing unit 102 is sufficient. It is determined whether or not there is. Specifically, it is determined whether or not the reliability of the analysis result is sufficient by using the following equation (2).

  When the reliability (R) of the analysis accuracy shown in Equation 2 is less than the reference value, a signal indicating that reanalysis is performed is sent to the component analysis unit 102. The reference value can be set in advance by the user.

  On the other hand, when the reliability of the analysis accuracy satisfies the reference value, the analysis value is stored in the data storage unit 106. Instead of the data storage unit 106, a data logger may be connected to the component analysis evaluation apparatus 100 via a USB or the like, and the analysis value may be stored in the data logger or the like. Further, it may be transmitted as data to another information processing apparatus or the like via the I / F (interface) 107.

  A display control unit 108 displays on the display device 109 analysis values of components analyzed by the component analysis unit 102, electrical conductivity measured by the EC measurement unit 103, reliability results determined by the data determination unit 105, and the like. .

  In the present embodiment, the water sampling device 101, the component analysis unit 102, and the EC measurement unit 103 need only be able to transmit / receive signals to / from the data processing unit 104 and the like. However, they may be configured as separate devices.

FIG. 2 is a flowchart illustrating an example of a processing procedure for analysis evaluation in the present embodiment.
In FIG. 2, when the process is started, in step S <b> 201, the data processing unit 104 determines whether the analysis of either the positive ion or the negative ion is completed in the component analysis of the sample water in the component analysis unit 102. Judging.

  If neither analysis has been completed as a result of this determination, the process waits until either analysis is completed. On the other hand, if one of the analyzes is completed as a result of the determination in step S201, in step S202, the data processing unit 104 uses the mathematical formula shown in Equation 1 from the sum of the equivalents of cations or anions. Calculate the conductivity.

  Next, in step S <b> 203, the data processing unit 104 determines whether the EC measurement unit 103 has already measured the electrical conductivity and received data from the EC measurement unit 103. As a result of this determination, if the electrical conductivity has already been measured by the EC measuring unit 103 and data has been received, the process proceeds to step S205. On the other hand, as a result of the determination in step S203, if the electrical conductivity has not been measured yet and no data has been received, the process proceeds to step S204.

  Next, in step S <b> 204, the EC measurement unit 103 measures the electrical conductivity of the sample water, and sends the measured electrical conductivity to the data processing unit 104. Next, in step S205, the data determination unit 105 acquires the electrical conductivity calculated in step S202 from the data processing unit 104, and compares the electrical conductivity measured in step S204 with the analysis performed in the component analysis unit 102. Evaluate the reliability of the results.

  Next, in step S206, as a result of the evaluation in step S205, it is determined whether the reliability falls below a predetermined reference value and reanalysis is necessary. If re-analysis is necessary as a result of this determination, the process returns to step S201 to perform re-analysis. At the time of reanalysis, a signal indicating that reanalysis is to be performed is sent to the water sampling apparatus 101 via the component analysis unit 102. The water sampling apparatus 101 collects sample water again from rivers, lakes, and the like, and the component analysis unit 102 performs analysis again.

  On the other hand, as a result of the determination in step S206, if the reliability exceeds a predetermined reference value and reanalysis is not required, all the evaluation of the reliability of the analysis result of the main ion component contained in the sample water is completed in step S207. Determine whether or not. That is, it is determined whether or not the evaluation of the reliability of the analysis result is completed for both positive ions and negative ions.

  As a result of the determination, if the reliability evaluation has not been completed yet, the process returns to step S201. On the other hand, if all the reliability evaluations are completed as a result of the determination in step S207, the process is terminated.

Moreover, in this embodiment, when a defect occurs in one component through a cation and an anion, the concentration of the lost ion can be estimated with a certain degree of reliability. For example, the concentration of bicarbonate ions can be estimated when bicarbonate ions (HCO ₃ ⁻ ) cannot be analyzed because there is no titration instrument in the analysis equipment.

A procedure for estimating the concentration of bicarbonate ions when bicarbonate ions (HCO ₃ ⁻ ) cannot be measured will be described with reference to the flowchart shown in FIG. First, in steps S201 to S206, a highly reliable analysis result is obtained for cations. In step S207, since the anion component analysis has not been completed, the process returns to step S201. Next, in step S201, it is determined that the analysis has been completed for all the anions except for the unmeasureable bicarbonate ions, and the process proceeds to step S202.

  In step S202, first, the concentration of bicarbonate ions is estimated. In general, an anion-cation balance calculation method using the fact that the sample water is electrically neutral is widely used. When this ion balance is used, the formula of the following formula 3 is used to calculate the bicarbonate ion. The concentration can be estimated.

  Thereby, the density | concentration of bicarbonate ion is estimated and electrical conductivity is calculated using the formula shown in the following formula 4. When calculating the electrical conductivity after estimating the missing value, if the equation shown in Equation 1 is used, the sum of the anion concentrations is always constant from the equation shown in Equation 3, and reanalysis is performed. Even if it goes, only the same electric conductivity is always calculated. Therefore, in this case, the electric conductivity is calculated from the concentration of each anion.

  Next, in step S203, since data has already been received from the EC measurement unit 103 in the analysis and evaluation of positive ions, the process proceeds to step S205.

  Next, in step S205, the reliability of the analysis result and the estimated value of the bicarbonate ion concentration is evaluated, and in step S206, it is determined whether reanalysis is necessary. If the reliability is lower than the reference value and reanalysis is required, the process returns to step S201, and the electrical conductivity calculated from the anion analysis value (excluding bicarbonate ion) and the bicarbonate ion estimation value is calculated. Repeat the anion analysis until the value meets the reference value. In this way, the estimated value can be given with certain reliability to the missing value.

  As described above, in the present embodiment, it is possible to prevent data loss at the time of analysis in the field-installed component analysis evaluation apparatus 100, and to collect reliable analysis values without human judgment. In addition, for samples whose reliability is less than the reference value due to feedback by reanalysis, the sample water is sampled again and analyzed, so there is no loss in sampling. Furthermore, since the analysis results were conventionally evaluated by ion balance, it was necessary to analyze both positive ions and negative ions. For example, only positive ions were analyzed to obtain highly reliable analysis results. Even if it is desired, the analysis result can be evaluated and a highly reliable analysis result can be obtained without analyzing the anion.

(Second Embodiment)
In the first embodiment, it is assumed that the on-site component analysis / evaluation apparatus 100 is installed in a water sampling facility installed in a river, a lake, or the like. On the other hand, when an atomic absorption spectrophotometer or ICP (Inductively Coupled Plasma) emission analyzer with high analysis accuracy is used as a component analyzer, the scale of the device increases, so it is a reality to install these devices on site. Not right. Therefore, in the present embodiment, when sample water is collected in advance and taken home, a component analyzer that collects water in an autosampler or the like in a plurality of containers, an EC measuring device that measures electrical conductivity, and an analytical evaluation A component analysis / evaluation system including an apparatus will be described.

FIG. 3 is a diagram illustrating a configuration example of the component analysis evaluation system in the present embodiment.
In FIG. 3, the system according to the present embodiment includes an analysis evaluation device 300, a component analysis device 320, and an EC measurement device 340. Since the basic configuration is the same as that of the first embodiment, the same number is assigned to the same configuration. The difference is that the water collection device 101 and the component analysis unit 102 of the first embodiment are the component analysis device 320, and the EC measurement unit 103 is the EC measurement device 340. With this configuration, data such as component analysis values and measured electrical conductivity are transmitted / received via the LAN 330.

  The component analyzer 320 is, for example, an ICP emission analyzer or an atomic absorption photometer, and an autosampler is used as the water sampling device. Note that an ICP emission analyzer, an atomic absorption spectrophotometer, and the like can be combined with other component analyzers because they can analyze with high accuracy but cannot measure anions.

  The EC measuring device 340 is an EC meter or the like, but uses a device capable of LAN connection. In the present embodiment, since the electrical conductivity is measured only once, the electrical conductivity of the sample water is measured in advance without performing the LAN connection with the EC measuring device 340, and the data is analyzed and evaluated. You may memorize it.

  As described above, according to the present embodiment, reliability can be ensured even in a device capable of high-accuracy analysis such as an ICP emission analyzer or an atomic absorption photometer, which has not been able to determine the reliability of the analysis value based on the conventional ion balance. Can be evaluated.

(Third embodiment)
In the present embodiment, an example in which the flow rate ratio of a river is measured using the on-site component analysis / evaluation apparatus 100 described in the first embodiment will be described. In order to measure the flow rate of a river, it is common to measure the flow velocity at several points in the river and further obtain the cross-sectional area of the river. When the river is small, a method of measuring the flow rate by installing a V notch in the river is used.

  However, the former requires personnel and labor, and the latter is not applicable when there is a lot of underground water or when the riverbed is covered with rocks. As a chemical method, a constant rate dilution method with tracer substances such as NaCl and radioactive substances may be used, but this is not necessarily the ideal dilution at the site, and there is also a risk of adverse effects on the environment. It is not used as a method for measuring river flow. In the present embodiment, the flow rate ratio is measured by measuring various chemical components that are stable as dissolved states among the chemical components of the river.

FIG. 4 is a schematic diagram illustrating an example of a river flow rate measurement system in the present embodiment.
In FIG. 4, in order to obtain a flow rate ratio (or flow rate / outflow amount) of the tributary river 403 with respect to the main river 401 after joining, the main river 401 after joining, the main river 402 before joining, and the branch river 403 are divided into First component analysis / evaluation apparatus 404, second component analysis / evaluation apparatus 405, and third component analysis / evaluation apparatus 406 are installed. Note that the functional configuration of each of the component analysis evaluation apparatuses 404 to 406 is the same as that of the first embodiment, and a description thereof will be omitted.

  When each component analysis evaluation device 404 to 406 performs a river component analysis and obtains a highly reliable component analysis result, the result is transmitted to the river flow rate measurement device 400. The river flow rate measuring device 400 calculates the flow rate of the river using the equation shown in the following equation 5 based on the component analysis results transmitted from the component analysis evaluation devices 404 to 406.

  When there is a chemical component separation between the main river 401 and the tributary river 403 after merging and there is no chemical change due to mixing of river water, the flow rate ratio can be calculated simply using this number 5. it can. At this time, it is necessary to use a component such as sodium ion, chloride ion, sulfate ion, dissolved silicon, etc., which is relatively stable as a dissolved state and can obtain a quantitative value with good analytical accuracy. The components with which the flow rate ratio calculation results of these multiple components substantially match are extracted, and the more the components with the substantially matching flow rate ratio, the higher the estimation accuracy of the flow rate ratio. In addition, components that deviate from the calculation result of the estimated flow rate ratio are expressed at the observation point based on the calculation result of the component, such as underground water, fountain outflow water, and outflow water from the waste disposal site. It is possible to evaluate the effects of mixing due to unspilled effluent and to calculate a reasonable mixing ratio with those effluents.

  In this embodiment, the flow rate ratio is determined using a component that is relatively stable as a dissolved state, such as sodium ion, chloride ion, sulfate ion, or dissolved silicon, and that provides a quantitative value with good analytical accuracy. However, instead of the ion concentration, the flow rate ratio can also be calculated using the actual measured value of electrical conductivity. Specifically, the flow rate ratio can be calculated by substituting the electrical conductivity measured by the EC measuring unit 103 of each component analysis evaluation apparatus 404 to 406 into the formula 5 instead of the ion concentration (C). it can.

FIG. 5 is a block diagram illustrating a functional configuration example of the river flow rate measuring apparatus 400 according to the present embodiment.
In FIG. 5, reference numeral 502 denotes a river water analysis unit, which receives component analysis results from the respective component analysis evaluation devices 404 to 406 via the I / F 501 and calculates the river flow rate ratio using the above-described formula 2. Then, the calculation result is stored in the data management unit 503. Further, as described above, when there is a component deviating from the solution, the mixing ratio of the effluent water is also calculated. Reference numeral 504 denotes a display control unit which causes the display device 505 to display the result calculated by the river water analysis unit 502.

FIG. 6 is a flowchart illustrating an example of a procedure for calculating the river flow rate ratio in the present embodiment.
In FIG. 6, when the process is started, it is determined in step S601 whether or not all the component analysis results have been obtained from the component analysis evaluation devices 404 to 406. If all the component analysis results are not obtained as a result of this determination, the process waits until all the component analysis results are obtained.

  On the other hand, if all the component analysis results are obtained as a result of the determination in step S601, the river flow rate ratio is calculated for each component in step S602 using the above-described equation (5). Next, in step S603, it is determined whether or not the river flow rate ratio has been calculated for each component using the above-described equation 5 for all components (including electrical conductivity). Note that all components are those that are relatively stable as a dissolved state as described above, and for which quantitative values can be obtained with good analytical accuracy, and it is difficult to calculate the river flow rate ratio. The river flow ratio does not have to be calculated from a certain component.

  As a result of this determination, if the river flow ratio is not calculated for all components, the process returns to step S602, and the river flow ratio is calculated for the remaining components. On the other hand, as a result of the determination in step S603, if the river flow ratio is calculated for all components, in step S604, components whose calculation results substantially match each other are extracted based on the calculation results of the river flow ratio for all components. To do.

  Next, in step S605, an estimated flow rate ratio is determined based on components whose calculation results substantially match. Next, in step S606, it is determined whether there is a component whose flow rate ratio calculation results do not match. If there is no mismatched component as a result of this determination, the process is terminated.

  On the other hand, if there is a component that does not match as a result of the determination in step S606, in step S607, the mixing ratio of the flow rate water is calculated from the difference between the estimated flow rate ratio determined in step S605 and the flow rate ratio calculated from the component. The process is terminated.

  As described above, in the present embodiment, it is possible to calculate the flow rate ratio of the tributary river 403 to the main river 401 after joining. In addition, it is effective for monitoring water pollution because it can evaluate the flow rate of the spring spill and the flow rate of the spill from the waste disposal site.

  In this embodiment, after obtaining all the component analysis results from each of the component analysis evaluation devices 404 to 406, the flow rate ratio of each component is calculated. However, when the component analysis results for a certain component are obtained. You may make it calculate the flow rate ratio in the component.
