摘　　要：3种极性农药甲硫威、嗪氨灵、氟啶虫胺腈暂无同时检测国家标准。为了出口水果和蔬菜的农药残留检测更方便、减少对环境污染并打破技术贸易壁垒,建立了纳米材料结合快速滤过型净化法用于测定出口水果和蔬菜中3种农药残留。在0.005~0.1 mg/L范围内,甲硫威、嗪氨灵、氟啶虫胺腈3种目标农药的线性关系良好,相关系数R~2均大于0.994;甲硫威、嗪氨灵、氟啶虫胺腈的定量限均为0.01 mg/kg,检出限均为0.005 mg/kg。3种目标农药的空白样品的总体加标回收率为66.0%~94.0%,变异系数为3.9%~11.0%。该方法准确、简便、可靠、经济,可用于出口水果和蔬菜中3种农药残留的测定。Currently,there are no national testing standards for three polar pesticides,methomyl,triforine,and sulfoxaflor.In order to facilitate pesticide residue detection in exported fruits and vegetables,reduce environmental pollution,and break down technological trade barriers.This article establishes a nanomaterial combined with rapid filtration purification method for the determination of three pesticide residues in exported fruits and vegetables.The results showed that within the range of 0.005 mg/L to 0.1 mg/L,there were good linear relationships for methomyl,triforine,and sulfoxaflor,with correlation coefficients R~2 all greater than 0.994.The quantitative limits of methomyl,triforine,and sulfoxaflor are all 0.01mg/kg,and the detection limits are all 0.005 mg/kg.The overall spiked recovery rates of blank samples for the three target pesticides ranged from 66.0%to 94.0%,with variation coefficients ranging from 3.9%to 11.0%.This method is accurate,simple,reliable,and economical,and can be used for the determination of three pesticide residues in exported fruits and vegetables.
