An Overview of Pretreatment Technology of Pesticide Residue Analysis

Pesticide residues bring serious harm to the environment and human health. More and more pesticides are introduced to the market, so that the detection technology of pesticide residue needs to be updated accordingly. Meanwhile sample preparation also becomes more challenging and important than before. This article simply introduces what are the pesticide residues and the influence factors to pesticide residues, how and why we analyze pesticide residues, and the steps and requirements of pretreatment. This article focuses on the principle, advantages and development tendency of different pretreatment technology, including solid phase extraction, solid phase microextraction and supercritical fluid extraction, etc.
