摘    要:研究了C18基质固相分散萃取(MSPDE),高效液相色谱-柱后衍生-荧光检测器测定小麦中6种氨基甲酸酯农药的方法.通过对色谱条件、基质固相分散材料的选择及其与样品的比例、洗脱条件以及加标回收率进行试验,建立和优化了小麦中6种氨基甲酸酯农药的MSPDE-HPLC-FLD多残留分析方法.结果显示,该方法对小麦样品中6种氨基甲酸酯农药的回收率为82.1%~94.0%,变异系数≤3.54%,方法的最低检出限为0.009 2~0.038 mg/kg.研究证明,基质固相分散萃取-液相色谱-柱后衍生方法简便、快速、准确、灵敏、节省样品和有机溶剂,可满足小麦中多种氨基甲酸酯农药残留同时检测的需要.

关 键 词:小麦  基质固相分散萃取  液相色谱  柱后衍生  氨基甲酸酯农药

Abstract:We studied a method for determining 6 kinds of carbamate pesticides in wheat using C18 matrix solid-phase dispersion extraction(MSPDE),high performance liquid chromatography,post-column derivation technique and fluorescence detector.Through the tests of the chromatographic conditions,the selection of matrix solid-phase dispersion material and the ratio of matrix solid-phase dispersion to the sample,the elution conditions and the standard recovery,we established and optimized the MSPDE-HPLC-FLD multi-residue...
Keywords:wheat  matrix solid-phase dispersion extraction  high performance liquid chromatography  post-column derivation technique  carbamate pesticide
