本文综述了近年来食品中农药残留分析的样品前处理技术 ,重点对超临界流体萃取法在食品农药残留分析中的应用及其联用技术进行了评述 ;同时对固相微萃取、微波辅助萃取和凝胶渗透色谱法进行了总结。对食品中农药残留分析技术的发展方向进行了讨论The progress on sample preparation techniques for analysis of the pesticide residues in foodstuffs was reviewed. The applications of the supercritical fluid extraction (SFE), solid-phase microextraction (SPME) , microwave aided extraction (MAE) and gel permeation chromatography (GPC) in analysis of pesticide residues in foodstuffs were described. Special attention was given to SFE technique and its hyphenation with gas chromatography (GC), high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS). The trends of sample preparation techniques for analysis of pesticide residues in foodstuffs were also discussed.福建省自然科学基金重点项目 (B0 2 2 0 0 0 1
