Organophosphorus detection system and method

Abstract

The invention relates to the field of food safety monitoring, and discloses an organic phosphorus detection system and an organic phosphorus detection method. According to the system and the method, liquid or mist solution to be detection is collected by a liquid collection device; the solution to be detected is guided to a ribbon through a catheter and reacts with a detection enzyme on the surface of the ribbon, and the color of the ribbon changes; a color sensor detects the color of the ribbon; the detected color is converted into the concentration value of organic phosphorus in the solution to be detected through a color-concentration conversion processor according to the predetermined correspondence relationship between the color and the concentration value of the organic phosphorus. By adopting the method and the system, the concentration of the organic phosphorus in an agricultural product planting environment is detected, the existence of the pesticide spraying in an agricultural product planting process can be determined, the actual concentration of the organic phosphorus can be detected, residue matters of the organic phosphorus are traced to the source and evidence is collected and acquired, and the problems that the current detection of the organic phosphorus seriously depends on the analysis of a professional large-scale instrument, the preparation of a sample is extremely complex, the detection speed is low and the like are solved.

Description

technical field [0001] The invention relates to the field of food safety monitoring, in particular to an organic phosphorus detection system and method. Background technique [0002] With the rapid development of my country's industry and the strategic adjustment of agricultural and industrial structures, especially the transformation of cultivation methods, the occurrence and harm of harmful organisms such as pest weeds, which were originally secondary or even quarantine, are becoming more and more serious, and drug resistance continues to rise. , leading to an increase in the amount of pesticides and the frequency of application. The abuse of highly toxic and high-residue pesticides has been repeatedly prohibited. Some use pesticides not in accordance with the regulations, and some even seriously violate the standards for safe use of pesticides. The use of highly toxic pesticides has resulted in a considerable portion of agricultural products with significantly exceeded pe...

Problems solved by technology

[0005] The purpose of the present invention is to provide a system and method for organophosphorus detection, so that by detecting the concentration of organophosphorus, it is determined whether there is pesticide spraying in the process of planting agricultural products, and the traceability of organophosphorus residues and evidence collection and acquisition are realized. At present, the detection of organic phosphorus relies heavily on the analysis of professional large-scale instruments, the sample preparation is extremely complicated, and the detection speed is slow.
