Description of the Invention: [Technical Field] The present invention relates to a method for detecting a multi-component chemical substance, and more particularly to a tester for a component and concentration of a contaminant contained in a contaminated solution [Prior Art] - Washing;: When cleaning, the tower needs to change the washing liquid in time to properly control the concentration of pollutants in the washing liquid. The main reason is that the concentration of the dirt in the washing liquid will affect the quality of the gas and liquid. The rate of transmission is reduced, resulting in a decline in efficiency. Usually, the replacement of the washing liquid is based on the experience of a fixed flow overflow method or a large amount of water exchange at a fixed time. The two methods may be excessively drained or insufficient, and the waste of resources or the efficiency of the washing tower may be ineffective. In addition, the inorganic acid-base scrubber also has a monitoring method for monitoring conductivity as a control factor; however, the ions in the water include not only the ions after the dissociation of the exhaust gas component in the water, but also the pH value. Add acid-base buffer solution in water, even because it uses high-conductivity recycled water. Therefore, the measured conductivity is not easy to correctly know the concentration of the contaminant ions. Therefore, in the case of low-concentration exhaust gas washing, the concentration of ions actually contributing from the waste gas in the washing liquid may be much lower than the original concentration in the water. Figure 1 is the conductivity of the inorganic acid scrubber washing solution and ? The relationship between the value of 11 and time can be seen as the conductivity is mainly affected by all the anions and cations in the soaking liquid (including sodium hydroxide (Na〇H) used to control the pH), and the washing is not correctly known. The ion concentration after the dissociation of the pollutants in the Suta. It is not reliable to monitor the conductance of 1251673 electrical conductivity as a control factor. It is not a good idea to use a fixed flow overflow method or a large amount of water exchange at a fixed time. However, 'there is a method of using Flow injecti〇n Analysis (FIA) to detect a single pollutant in a single water sample, and 5 is for laboratory use only, but cannot analyze the components of various pollutants. . Therefore, there is a need for a method and apparatus for analyzing multi-contaminant components or multiple samples of multi-contaminant components in a single sample, and more preferably applying the method to industrial process waste liquids, or monitoring of wastewater contaminants, or In order to monitor the concentration and composition of pollutants contained in the washing liquid of the inorganic acid-base scrubber, it becomes a control factor for controlling the replacement of the 10 strips.

It is the starting time of the washing tower operation, so the washing liquid does not contain any pollutants at this time. As the washing tower starts to clean the pollutants, the concentration of pollutants contained in the washing liquid tends to increase (please refer to Figure 4B). Time concentration value change). When the detected concentration of a key pollutant component exceeds a set concentration, the detection message can be controlled by a control element.

In this embodiment, the detection concentration of chlorine ions in the washing liquid is selected as the key for controlling the replacement of the washing liquid 12 1251673. It can be seen that when the detection concentration of the chlorine ions is too high, the washing liquid only replaces part of the water amount, that is, The chloride ion concentration can be lowered, and the processing efficiency of the washing tower can be maintained. The carrier fluid used in this embodiment is a Bdj30 solution having a concentration of 5 1 ·25 X 10-4% (w/v), and the reagent used is Mercuric thiocyanate solution and iron oxalate iron. (ferric nitrate) solution, methanol, and a mixed solution of water (1 : 1 : 1 : 5). The Mercuric thiocyanate solution is a solution of 0.417 g of Hg(SCN)2 dissolved in 100 mL of methanol; the ferric nitrate solution is 20.2 g of Fe(N03)3.9H20 10 dissolved in 50 mL of water, diluted after adding two drops of concentrated HN03 Up to 100 mL The retention element 40 used in this embodiment is a Teflon column having a length of 7-8 inches and an inner diameter of 0.03 inches. Pump element 50 is a syringe pump having a volume of 2500 pL. For the operation principle of this embodiment, reference may be made to the schematic diagram of FIG. 3. Figure 3 is a graphical representation of the concentration of contaminants in the wash solution as a wash fluid replacement control factor. As the operating time of the scrubber increases, the concentration of contaminants in the wash liquid increases, resulting in a decrease in the efficiency of the wash liquor to treat contaminants. However, there are many types of contaminant components in a wash column. In the present embodiment, one of the key components affecting the processing efficiency of the washing liquid can be selected, so that the detected concentration value of the single 20 component can be regarded as the control condition for replacing the washing liquid. Therefore, in order to maintain the processing efficiency of the washing tower, when the detected concentration value of the component has exceeded the set concentration, the pollutant concentration value of the washing liquid detected by the device of the present invention can be fed back to the control unit in the washing tower. Replace the washing liquid in an appropriate amount. 13 1251673 Figure 5 shows the change of the cleaning efficiency in the washing liquid obtained by actual monitoring. (IV)... During the night, “the concentration of wood is washed with 5 10 15 20. The operation is the same as the assumption shown in Figure 3. With the washing The efficiency of the liquid treatment of the tower liquid is reduced. The method and the device for the multi-component of the liquid-washing product can be detected in a short period of time, and the composition of the chemical substance is reduced. The experiment operation is more convenient, and the operation time is reduced, and the concentration change of the multi-component in the sample can be monitored. The multi-component chemical substance detection method and the I-set of the invention can be applied to the 洗涤 monitoring washing tower washing liquid. Concentration of pollutants, as A; n± ^ . ^ ^ ^ as the control factor to determine the rate of replacement of washing liquid: the amount of control factor to effectively maintain the treatment efficiency of the washing tower Inspecting industrial process waste liquid, or inspection of wastewater contaminants, etc. ...'
