Pesticide residues have serious harm to the environment and human health. With the increasing types of pesticides, pesticide residue detection technology also needs continuous updating, the continuous development of detection technology, prompting sample preparation has become an important issue. This article briefly introduces the influencing factors of pesticide residues and pesticide residues, the links and purposes of pesticide residue analysis, the steps and requirements of pretreatment, and mainly introduces nine sample pretreatment methods, such as solid-phase extraction, solid-phase microextraction and supercritical fluid extraction The principle of technology, advantages and disadvantages and development situation.
