Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
Fig. 1 shows a schematic diagram of a hybrid architecture for an automatic atmospheric peroxide monitoring system according to a specific embodiment of the present application. Similar to the prior art, the atmospheric peroxide automatic monitoring system of the present application is generally comprised of two parts, including a sampling device 100 and an analysis device 200. The sampling device 100 continuously collects the peroxides in the atmosphere and then continuously transmits the peroxides to the analysis device 200 through the first connecting pipeline 300, wherein the analysis device 200 analyzes the peroxides in the sample by adopting a fluorescence detection method to respectively obtain the concentration of the total peroxides and the concentration of the total organic peroxides in the sample, and the concentration of the hydrogen peroxide in the atmosphere can be obtained through conversion.
The analysis device 200 adopts a fluorescence detection method to analyze peroxide in a sample, and the principle is that the peroxide can convert non-fluorescent p-hydroxyphenylacetic acid into 2,2 '-dihydroxy-biphenyl-5,5' -diacetic acid with strong fluorescence under the action of horseradish peroxidase, the fluorescence intensity of a fluorescent substance is detected by a fluorescence detector to determine the concentration of the peroxide, and finally, the concentrations of total peroxide and organic peroxide can be calculated by utilizing a simulated regression equation of a calibration curve, and the concentration of hydrogen peroxide is obtained by calculation.
As shown in fig. 1, the analysis device 200 includes a first mixing tube 21, a second mixing tube 22, and a third mixing tube 23 connected horizontally end-to-end in series. The inlet end of the first mixing tube 21 is respectively connected with the first connecting pipeline 300, the first buffer solution bottle 201 and the second buffer solution bottle 2011 through a four-way joint S1, the inlet end of the second mixing tube 22 is respectively connected with the outlet end of the first mixing tube 21 and the fluorescent reagent bottle 202 through a three-way joint S2, and the inlet end of the third mixing tube 23 is respectively connected with the outlet end of the second mixing tube 22 and the alkaline solution bottle 203 through a three-way joint S3; the outlet end of the third mixing pipe 23 is connected with a vertically arranged sample collector 24, and the middle part of the sample collector 24 is connected with a fluorescence detector 500 through a pipeline.
The upper end of the sample collector 24 is connected with the outlet end of the third mixing pipe 23, the lower end of the sample collector 24 is connected with an air pump P12, and the sample collector has the function of discharging redundant samples out of the analysis system, so that excessive liquid is prevented from being accumulated in the collecting pipe, and the peroxide cannot be monitored in real time and on line. A micro pump P10 is disposed in a pipeline connecting the middle of the sample collector 24 to the fluorescence detector 500 for pumping the liquid into the fluorescence detector 500.
The capture liquid sample dissolved with peroxide is pumped into the analysis apparatus 200 through the first connection pipe 300 by the micro pump P2, and is merged with the first buffer solution pumped out from the first buffer solution bottle 201 by the micro pump P4 at the cross S1, or merged with the second buffer solution pumped out from the second buffer solution bottle 2011 by the micro pump P5 at the cross S1 (the first buffer solution and the second buffer solution are not pumped in simultaneously), and then is sufficiently mixed in the first mixing pipe 21; thereafter, the sample flows out of the first mixing tube 21, joins the fluorescent reagent pumped out of the fluorescent reagent bottle 202 by the micro pump P6 at the three-way S2, and then undergoes a reaction in the second mixing tube 22; the reacted sample flows out of the second mixing tube 22, joins the alkali solution pumped out of the alkali solution bottle 203 by the micro pump P8 at the tee S3, and then is fully mixed in the third mixing tube 23.
The first buffer solution and the second buffer solution have the same functions of removing heavy metals in the solution to avoid interference, and simultaneously, the pH value is adjusted to be about 6.8 suitable for carrying out fluorescence reaction. The buffer solution in the second buffer solution bottle 2011 is different from the buffer solution in the first buffer solution bottle 201 in that catalase is further added to the buffer solution in the second buffer solution bottle 2011. The fluorescent reagent is used for generating the 2,2 '-dihydroxy-biphenyl-5,5' -diacetic acid which emits fluorescence, and the alkali liquor is used for finally adjusting the pH value of the detection solution to be 10.0-10.5 which is most suitable for fluorescence detection, so that the detection method has the highest sensitivity.
When pumping the second buffer solution by the micro-pump P5 is chosen, the hydrogen peroxide in the capture liquid sample with the peroxide dissolved therein can be decomposed by catalase, so that no hydrogen peroxide is present during the subsequent detection, and the last detected peroxide concentration in the analysis device 200 is completely the organic peroxide concentration in the atmosphere. Alternatively, the first buffer solution is pumped through the micro pump P4 and the total concentration of peroxide in the atmosphere is determined. Thus, finally by calculation, the concentration of hydrogen peroxide in the atmosphere can be obtained by subtracting the concentration of organic peroxide obtained by pumping the second buffer solution from the total peroxide concentration obtained by pumping the first buffer solution. According to the application, the first buffer solution and the second buffer solution can be pumped in by switching, and the detection of various peroxides in the atmosphere can be realized by using the same fluorescence detector 500, so that the system structure is simplified, and the cost is saved.
Through the above description of the automatic monitoring system for the peroxide in the atmosphere, the final detection result of the peroxide in the atmosphere is obtained by calculating the detection result of the fluorescence detector on the amount of the 2,2 '-dihydroxy-biphenyl-5,5' -diacetic acid which fluoresces. Thus, the inventors believe that the higher the accuracy of the amount of fluorescing 2,2 '-dihydroxy-biphenyl-5,5' -diacetic acid produced by the reaction, the higher the accuracy of the final peroxide detection.
Based on this analysis, the inventors set a mixing tee S61 between the inlet end of the second mixing pipe 22 and the tee S2, the inlet end of the second mixing pipe 22 was connected to the tee S2 and a nitrogen gas cylinder K61 through the mixing tee S61, respectively, and nitrogen gas in the nitrogen gas cylinder K61 was pumped into the mixing tee S61 by a micro pump P61.
This application is after fluorescence reagent pump goes into the system, through micropump pump income nitrogen gas, forms the bubble through nitrogen gas, and the mixed liquid after adding fluorescence reagent stirs the mixture through the bubble, has promoted fluorescence reagent's mixture. After the mixed structure is added through the test of the calibration solution, the lower limit of the peroxide detected by the subsequent fluorescence detector can be improved by one order of magnitude. Moreover, the mixing structure is added without increasing the length of a system pipeline to promote mixing, the original system structure is not required to be changed, the detection precision is improved, and the cost and the detection time are saved.
