固相萃取技术在食品痕量残留和污染分析中的应用

食品痕量残留和污染分析中,样品的前处理极为重要,也是其难点所在。由于食品和农产品样品的多样性和复杂性,目前还没有一种前处理技术能够适合所有情况下的所有样品。本文对近年来发展起来的新型固相萃取技术如固相微萃取、搅拌棒吸附萃取、基质固相分散萃取、分子印迹固相萃取、免疫亲和固相萃取、整体柱固相萃取、碳纳米管固相萃取等在食品痕量残留和污染分析中的应用进行了综述,对未来的发展前景作了展望。

Recent applications of solid-phase extraction techniques for analysis of trace residues and contaminants in food

The determination of trace residues and contaminants in food often requires extensive sample extraction and preparation prior to instrumental analysis.Due to the multiplicity and complexity of food matrices,it is not possible to use only one sample preparation technique.This review introduces the application of some new techniques of solid-phase extraction(SPE) in recent years,such as solid-phase microextraction(SPME),stir-bar sorptive extraction(SBSE),matrix solid-phase dispersion(MSPD),molecularly imprint...
