A detection kit and method for dicofol

Abstract

The invention discloses a detection kit and a method for dicofol. The principle that the activity of lipase can be increased along with the increase of the concentration of the dicofol is utilized; whether the dicofol exists or not is detected by detecting the lipase activity, so that the dosage of an organic solvent is reduced, the detection limit is improved, strong acid and an organic solvent with foul smell are prevented from being used, the operation process is simplified, the detection efficiency is improved, and the method is suitable for field operation and rapid detection.

Description

technical field

[0001] The invention relates to the field of organic compound detection, in particular to a kit and method for detecting dicofol. Background technique

[0002] Dicofol is a low toxicity and high efficiency organochlorine acaricide, insoluble in water, soluble in various organic solvents, and has low toxicity to humans and animals. This kind of pesticide is a special pesticide for cicada mite pests. It has a good control effect on adults, nymphs and eggs. In addition, its structure is stable, its decomposition is slow, and its residual effect is long. Therefore, it was popularized and applied in my country's tea production in the late last century. . However, the production of most dicofol products uses DDT as the main intermediate, and the residual refining process is not up to standard, resulting in excessive DDT content in a large number of finished products. Therefore, when dicofol is sprayed, a certain amount of DDT is also mixed, so in the tea gardens a...
