Method for detecting organophosphorus pesticide residues

The invention relates to the technical field of pesticide residue detection, and discloses a method for detecting organophosphorus pesticide residues. The device for detecting organophosphorus pesticide residues mainly comprises smart equipment, optical equipment, a casing and a cuvette. The specific operation comprises the following steps of adding a fluorescent display reagent after the organicphosphorus pesticide is hydrolyzed in the cuvette, placing the solution in the casing, finding that the solution emits fluorescence under ultraviolet light irradiation, photographing the fluorescencewith the smart equipment for gray-scaled processing, further calculating the concentration of organophosphorus pesticide residues, and outputting the test results. The invention can simultaneously detect the residual concentrations of organophosphorus pesticides such as dimethoate, malathion, demeton, phorate and disulfoton. The beneficial effect of implementing the invention is that it is convenient for on-site detection
