摘  要:
建立测定蔬菜中常用18种农药的简便、快速的气相色谱-质谱联用多残留检测方法.以乙腈提取样品,伯仲胺(PSA)分散净化,使用气相色谱-质谱仪以选择离子监测模式进行分析测定.在设定色谱条件下,18种农药在0.036~0.36mg/kg范围内线性良好,添加0.05、0.1mg/kg农药混合溶液的平均回收率在75%~117%之间,检测限在1.0~14.8μg/kg范围内.本方法操作方便、重现性良好,为检测蔬菜中农药多残留提供可靠的分析方法.

摘  要:
A simple and rapid method was developed to determine 18 pesticide residues in vegetables by GC-MS.Pesticides were extracted with acetonitrile and cleaned up by dispersive solid phase extraction using primary secondary amine and analyzed by GC-MS under selective ion monitoring mode.Under the optimal chromatographic conditions,a good linear relationship was obtained in the concentration range of 0.036 to 0.36mg/kg.Average recoveries of the pesticides in blank matrix spiked at 0.05 mg/kg and 0.1 mg/kg ranged from 75% to 117%.The limits of detection for 18 pesticides were in the range of 1.0 to 14.8 μg/kg.This method is simple and reproducible and can offer a reliable analytical approach for determining pesticide multi-residues in vegetables.
