Abstract: Soil sample pretreatment technology mainly includes extraction, purification, concentration and other technologies, the three usually have no strict boundaries. In pesticide residue analysis, sample pretreatment is the basis of pesticide residue detection, it is the key step, directly related to the accuracy and precision of the whole pesticide residue analysis process. Sample pretreatment needs to extract the components from the sample to the maximum extent, to eliminate the interfering substances to the greatest extent, to reduce the experimental error, and to avoid contamination of the detection instrument. At the same time, due to the variety of samples, different samples need different pretreatment methods, so sample pretreatment technology is still the difficulty of pesticide residue detection technology at home and abroad.Summary: With the development of science and technology, there are many new pesticide varieties with low dosage and residue. Meanwhile, the pesticide residue limit requirements are getting lower and lower, which put forward higher requirements for pesticide residue detection technology.References: Wauchope RD, Yeh S, Linders JB, Kloskowski R, Tanaka K, & Rubin Bet al.
