Method for rapidly determining various pesticide residues in ecological textiles based on liquid chromatography-triple quadrupole-tandem mass spectrometry technology

Abstract

According to a method for rapidly determining various pesticide residues in ecological textile based on a liquid chromatography-triple quadrupole-tandem mass spectrometry technology, provided by the invention, an improved QuEchERs technology is used as a pretreatment means, and a high-sensitivity liquid chromatography-triple quadrupole-linear acceleration ion trap tandem mass spectrometer is used as a detection means, a rapid screening and confirmation technology for simultaneously detecting various common pesticide residues such as organophosphorus, pyrethroid and carbamate insecticides, bactericides and herbicides in the ecological textile matrix is established, and the method has the advantages of multiple detection types, low detection limit, short detection period, high detection efficiency and the like.

Description

technical field [0001] The invention discloses the technical field of pesticide residue detection, and in particular relates to a method for quickly measuring various pesticide residues in ecological textiles based on liquid chromatography-triple quadrupole-tandem mass spectrometry technology. Background technique [0002] With the continuous development of society and the continuous improvement of people's life philosophy, people's requirements for clothing are not only warm, comfortable and fashionable, but also environmental protection, health and other elements. This means that people pay more and more attention to the processing and production of ecological textiles. Ecological textiles refer to those products in the textile industry that meet the technical requirements of environmental labeling products and pass the test, and use harmless or less harmful raw materials to the surrounding environment, and rationally use these raw materials to produce harmless products to...

AI Technical Summary

Problems solved by technology

[0006] In view of this, the present invention provides a method based on liquid chromatography-triple quadrupole-tandem mass spectrometry to quickly measure multiple pesticide residues in ecological textiles, to at least solve the problem of pesticide residue detection techniques in the past, which can only realize one or several pesticide residues. The detection of pesticide residues has problems such as long detection cycle, low detection efficiency, inaccurate confirmation, low detection sensitivity and high detection limit.
