摘　　要：Pesticide residues are related to environmental pollution,food safety and other issues,and sample processing is a key link in the whole analysis and detection process.Therefore,it is of far-reaching significance to establish a reliable and safe pretreatment technique for pesticide detection.QuEChERS(quick,easy,cheap,effective,rugged and safe),as a pretreatment method for pesticide residue analysis,is widely used in the field of testing and analysis because of its characteristics of rapidity,simplicity,low cost and high efficiency.In this paper,the effects of material selection involving extractants,analyte protectants and purification agents and their ratio optimization in QuEChERS method on the improvement of pretreatment efficiency were analyzed,hoping to provide further technical reference for expanding the pretreatment technique.
