| 摘 要： | 目的:采用QuEChERS样品前处理方法与在线凝胶色谱-气相色谱-质谱联用仪(GPC-GC-MS)联用,建立独活中27种农药多残留的快速检测方法.方法:以1％醋酸的乙腈为提取溶剂,超声提取,分散固相萃取净化,采用在线GPC-GC-MS分析,以选择离子检测(SIM)模式检测.结果:27种农药成分的峰面积与其浓度均有良好的线性关系,相关系数均在0.994 3 ～0.999 9.方法的检出限和定量限分别在0.037 5 ～3.040 0 μg·L和0.125 0 ～ 10.100 0uLg·L-1；在加标0.1 mg·L-1情况下,回收率均在61.7％ ～114％,RSD 1.03％ ～ 13.9％.结论:该方法简单、快速、选择性好、灵敏度高,符合农药多残留检测的要求,可用于独活中27种农药多残留的测定.
