摘要：

本文运用农药多残留分析中的一种简便、快速、价格低廉的分析方法-QuEchERS法。其采用一种新的样品前处理方法,从蔬菜中提取净化残留农药(包括11种有机磷农药),运用GC/MS进行分析检测,根据有机磷农药种类差异,其最小检出限在5.6~18.2g/kg之间,回收率在67.7%~105.3%之间,相对标准偏差不大于10.6%,实验表明本方法适用蔬菜中有机磷农药多残留分析。

Abstract: This article used QuEchERS method,known as to be quick,easy,cheap,effective,rugged and safe,to determinate 11 pesticides residues in vegetables.After extraction and cleanup,the samples were detected by GC/MS.The LOQ and average recovery ratio were 5.6~18.2μg/kg and 67.7%~102.3% respectively,while RSD was less than 10.6%.The results show the QuEchERS method can be used for the determination of organophosphorus pesticide residues in vegetables.
