Problems solved by technology

This method has some shortcomings. First, the sample collection and transportation process requires considerable manpower and material resources, and the cost is high. Second, when there are many sampling points in the field and the distance from the laboratory is long, a large number of samples cannot be transported back to the laboratory immediately. The analysis is hysteresis; the third is that there is no sample storage conditions such as freezing and acidification in the field, and improper storage of samples will have a great impact on the experimental results

Embodiment

[0042] This embodiment provides an on-site rapid enrichment and purification device for psychoactive substances in water environment with simple structure, convenient operation, low energy consumption, good pre-treatment quality and high efficiency. see figure 1 , the device includes a liquid storage bottle 1, an eluent bottle 2, a first activation liquid bottle 3, a first liquid injection pump 4, an enrichment tray 5, an adsorption trap 6, a sample bottle 7, a second liquid injection pump 8, a waste Liquid bottle 9 and elution device.

[0043] The liquid storage bottle 1 is made of 500mL borosilicate glass, and is used to store the water sample to be treated; The inlet pipe connection; the filter head 13 is provided with a multi-layer pore diameter of 0.45 µm, a diameter of 5 cm acetate fiber or glass fiber filter membrane, used to filter the water sample, because the location of the water sample is different, so the water The impurity content is different in the sample, us...

example 1

[0061] The automatic sampler is used to collect sewage samples in the river, and the sample collection is immediately pretreated by the device of the present invention on site, and then sent back to the laboratory for instrument detection. At the same time, the samples are quickly sent back to the laboratory for processing and testing with traditional methods, and the results are as follows: figure 2 shown.

[0062] figure 2 Among them, the dark column is the traditional method, and the light column is the rapid purification and enrichment method of the device of the present invention. It can be seen that the accuracy rate reaches 92.5%.

example 2

[0064] The automatic sampler is used to collect sewage samples at the entrance of the sewage treatment plant, and the sample collection is immediately pretreated by the device of the present invention on site, and then sent back to the laboratory for instrument detection. At the same time, the samples are quickly sent back to the laboratory for processing and testing with traditional methods, and the results are as follows: image 3 shown.

[0065] image 3 Among them, the dark column is the traditional method, and the light column is the rapid purification and enrichment method of the device of the present invention. It can be seen that the accuracy rate reaches 92%.

[0066] It can be seen that using this device to purify and enrich samples and then store them is fast, low energy consumption, and easy to operate, and the accuracy of the pre-treated samples can still reach 92%~92.5%, or even higher. High, fully meet the requirements. In addition, it can also reduce the req...

Abstract

The invention provides an on-site rapid enrichment and purification device and method for psychoactive substance in a water environment. The device comprises a liquid storage bottle, a leacheate bottle, a first activation liquid bottle, a first liquid injection pump, an enrichment disc, an adsorption trap, a sample bottle, a second liquid injection pump, a waste liquid bottle and an elution device. The outlet of the liquid storage bottle and the outlet of the first liquid injection pump are respectively connected with an inlet pipeline of the enrichment disc; the leacheate bottle and the firstactivation liquid bottle are connected with an inlet pipeline of the first liquid injection pump; the outlet of the enrichment disc and the outlet of the second liquid injection pump are respectivelyconnected with an inlet pipeline of the adsorption trap; the sample bottle and the waste liquid bottle are respectively connected with an outlet pipeline of the adsorption trap; and the elution device is connected with an inlet pipeline of the second liquid injection pump. The device is simple in structure and reasonable in design; and when the device is used for pretreatment of the sample underthe field condition, the speed is fast, the energy consumption is low, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to an on-site rapid enrichment and purification device and method for psychoactive substances in a water environment. Background technique [0002] Psychoactive substances refer to substances from outside the human body that can significantly affect people's mental activities and lead to addiction after smoking and use, mainly including central nervous system depressants, stimulants, marijuana, hallucinogens, opioids, etc. Most psychoactive substances belong to the State controlled class of substances, substances that are illegally abused and are known as "drugs". Currently, the widespread abuse of psychoactive substances has become a growing global concern. At the same time, due to abuse, psychoactive substances and their metabolites enter the environmental water body, which brings greater risks to the ecological environment and human health. [0003] Due to the social and environmental problems caused by the abuse of psychoact...
