摘　　要：季铵盐类农药属于强碱性极性有机阳离子化合物,易残留在环境中。传统的萃取方式难以对复杂基质中的痕量残留净化富集,其前处理方法一直是检测中的难点。近年来随着固相萃取材料不断更新与发展,固相萃取法已取代液-液萃取法成为季铵盐残留检测中主要应用的前处理方法。全面地描述了各类基质中季铵盐残留检测的前处理方法,重点分析与论述了目前常用的固相萃取材料的性质及优缺点,对其在前处理分析方法中涉及的重要方面做了较全面的分析与论述。Quaternary ammonium pesticides which belong to strongly alkaline,polar organic compounds,are easy to remain in the environment.The traditional liquid-liquid extraction method is difficult to trace the residues in complex matrices purification enrichment,and detection of residues has been the difficulty of pre-treatment.In recent years,the solid-phase extraction adsorbent material constantly update with the development of solid-phase extraction,taking the place of the liquid-liquid extraction method gradually,and the former has been the mainly applied pre-treatment method in detecting the quaternary pesticide residues.The various types of pre-treatment methods concerning the matrix quaternary pesticide are comprehensively overviewed.The properties,advantages and disadvantages of solidphase extraction materials are mainly analyzed and discussed.The comprehensive analysis and elaboration of significant aspects concerning the pre-treatment method in solid-phase extraction are also involved.
