Similar to the prior art, the atmospheric peroxide automatic continuous monitoring system of the present application is generally composed of three parts, including a sampling device 100 and a first 200 and a second 2001 analysis device. The sampling device 100 continuously collects the peroxides in the atmosphere and then continuously transmits the peroxides to a first analysis device 200 and a second analysis device 2001 through a first connecting pipeline 300, wherein the first analysis device 200 and the second analysis device 2001 both analyze the peroxides in the sample by using a fluorescence detection method, the first analysis device 200 obtains the total concentration of the peroxides in the atmosphere, and the second analysis device 2001 obtains the concentration of the organic peroxides in the atmosphere.

The upper end of the first sample collector 24 in the first analysis device 200 is connected to the outlet end of the third mixing pipe 23, and the lower end of the first sample collector 24 is connected to an air pump P12, which is used for discharging the redundant sample out of the analysis system, so as to avoid the excessive liquid from accumulating in the collecting pipe, and thus the peroxide cannot be monitored in real time and on line. The second sample collector 241 of the second analysis device 2001 has an upper end connected to the outlet end of the sixth mixing pipe 231 and a lower end connected to an air pump P13 functioning as the air pump P12. A micro pump P10 is disposed in a pipeline connecting the middle of the first sample collector 24 and the first fluorescence detector 500, and is used for pumping the liquid into the fluorescence detector 500. A micro pump P11 is arranged in a pipeline connecting the middle part of the second sample collector 241 with the second fluorescence detector 5001.
In the first analysis device 200, the capture liquid sample dissolved with peroxide is pumped into the first analysis device 200 through the first connecting pipe 300 by the micro pump P2, joins the buffer solution pumped out from the first buffer solution bottle 201 by the micro pump P4 at the tee S1, and then is fully mixed in the first mixing pipe 21; thereafter, the sample flows out of the first mixing tube 21, the fluorescent reagent pumped out of the first fluorescent reagent bottle 202 by the micro pump P6 joins at the three-way S2, then the reaction is performed in the second mixing tube 22, and the reacted sample flows out of the second mixing tube 22, joins at the three-way S3 with the alkali solution pumped out of the first alkali solution bottle 203 by the micro pump P8, and then the sufficient mixing is performed in the third mixing tube 23.

Wherein, the buffer solution is used for 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. However, the buffer solution in the second buffer solution bottle 2011 differs 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 the second buffer solution is pumped in by the micro-pump P5, H in the capture liquid sample with peroxide is dissolved 2 O 2 Can be decomposed by catalase, so that H is detected in the subsequent detection process 2 O 2 Is not present, the last peroxide concentration detected by the second analysis device 2001 is now completeIs the concentration of organic peroxide in the atmosphere. While the first buffer solution was pumped by the micro pump P4, it was checked that the total concentration of peroxide in the atmosphere was obtained. The application can automatically, continuously and simultaneously realize the continuous monitoring of the total peroxide concentration and the continuous monitoring of the organic peroxide concentration through the first analysis device 200 and the second analysis device 2001, and the detection of the total peroxide concentration and the organic peroxide concentration does not need to be interrupted or switched in the whole monitoring process, so that the detection efficiency is improved.
Through the above description of the automatic continuous 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 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, for the first analysis apparatus, the inventor provided a first 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 the first nitrogen gas cylinder K61 through the first mixing tee S61, respectively, and nitrogen gas in the first nitrogen gas cylinder K61 was pumped into the first mixing tee S61 by the micro pump P61.
