加速溶剂萃取技术(ASE)在农药残留分析中的应用 赵海香 摘要：加速溶剂萃取(ASE)是采用常规溶剂，在较高的温度(50℃~200℃)和压力(1000~3000psi或10.3~20.6MPa)下对固体或半固体样品进行萃取的新颖的样品前处理技术，具有操作简便、省时省溶剂、减少有机溶剂对环境的污染、萃取操作自动化的特点。介绍了A S E 的原理、仪器操作和影响因素，并概述了A S E 在土壤、蔬菜、水果及生物样品残留农药提取中的应用，提取的农药种类有有机氯、有机磷和多种除草剂。特别是在多残留检测中，加速溶剂萃取技术更易于同时提取不同类别的多种农药，简化净化过程，并在快速检测方面发挥重要作用。加速溶剂萃取的提取效率和索氏提取相当。
