摘 要: | 采用QuEChERS前处理方法和在线凝胶渗透色谱-气相色谱质谱联用仪(gel permeation chromatography-gas chromatography/mass spectrometry,GPC-GC/MS)快速测定蔬菜中24种多农药残留。样品经乙腈提取,净化采用分散固相萃取的方式,加标浓度为0.1 mg/kg,油麦菜样品中的24种农药回收率大部分在70%~120%,24种农药的检出限范围在0.000 2~0.009 mg/kg,线性范围0.025~0.30 mg/L,相对标准偏差在1.41%~10.05%,满足农药多残留的分析要求。实验表明,QuEChERS方法提取和净化使样品前处理更为简单、方便、快速,GPC-GC/MS系统中的GPC柱弥补了QuEChERS方法去除干扰物不彻底的问题,能更准确地检测出蔬菜中多农药残留,检测灵敏度高,重现性好。
