英文摘要:

      Sample pretreatment technology is an important factor of guarantee of the accuracy of sample detection. With the development of detection techniques of agricultural products, pretreatment techniques of pesticide residues in grain have been developed from traditional pretreatment stage to a new high efficiency pretreatment stage. Through a literature searches, in chronological order as well as national development, a series of pretreatment techniques of solid-phase extraction, solid-phase micro extraction, supercritical fluid extraction, microwave aided extraction, gel permeation chromatography, matrix solid-phase dispersion extraction, accelerated solvent extraction, immunoaffinity chromatography, and dispersive solid-phase extraction were introduced and overviewed briefly in application of detection method of pesticide residues in grain in this paper. The commonly used extraction solvents, purifications and analytical instruments of determination of pesticide residues in grain were summarized, and how to use pretreatment techniques in routine inspection was recommended and prospected. Furthermore, this article can provide a reference for people in the field of food safety research and applications in further research.
