摘　　要：实验研究了农产品中阿维菌素Qu ECh ERS测定方法,样品通过乙腈震荡提取,丙基乙二胺(primary secondary amine sorbent,PSA)、十八(烷)基硅烷C18(octadecyl silane,ODS C18)简称C18、多壁碳纳米管(multi walled carbon nanotubes,MWCNTs)净化,过滤膜上机检测。结果表明,当PSA、C18、CNT用量分别为0.5 g,1 g,0.03 g时,净化效果最好,回收率高。回收率在80%~120%之间,可以达到检测要求,阿维菌素检出限为0.02 mg/kg,RSD小于10%,满足实验要求。The QuEChERS method for the determination of abamectin in agricultural products was studied. The sample was extracted by acetonitrile and purified by PSA, C18 and MWCNTs and filtered by membrane and then tested. The results show that when the dosage of PSA, C18 and CNT were 0.5 g, 1 g and0.03 g respectively, the purification effect was the best and the recovery rate was high. The recovery rate is between 80 %~120 %, which can meet the detection requirements. The detection limit of abamectin was 0.02 mg/kg, and the RSD was less than 10 %, which met the experimental requirements.
