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 imprinted solid-phase extraction (MISPE) , immunoaffinity-based solid-phase extraction (IASPE), monolithic solid-phase extraction, carbon nanotube solid-phase extraction, in the analysis of trace residues and contaminants in food. At last, future developments in this field are outlined.
食品中痕量残留物和污染物的测定通常需要在仪器分析之前进行大量的样品提取和制备。由于食品基质的多样性和复杂性，不可能仅使用一种样品制备技术。本文综述了近年来一些新型固相萃取（SPE）技术，如固相微萃取（SPME）、搅拌棒吸附萃取（SBSE）、基质固相分散（MSPD）、分子印迹固相萃取（MISPE）、免疫亲和固相萃取（IASPE）、整体式固相萃取、碳纳米管固相萃取，在食品痕量残留物和污染物分析中的应用。最后，概述了该领域未来的发展。
