摘要

建立了高效液相色谱-电喷雾电离串联质谱同时检测茶叶中阿维菌素、啶虫脒、涕灭威、甲萘威、克百威、萎锈灵、除虫脲、烯酰吗啉、唑螨酯、吡虫啉、茚虫威、甲霜灵、灭多威、腈菌唑、咪酰胺、丙环唑、鱼藤酮、西玛津、戊唑醇19种农药残留的方法。试样经QuEChERS方法进行前处理，超高效液相色谱-电喷雾电离串联质谱法测定,外标法定量。除虫脲的质量浓度在5~75 μg/L范围内线性关系良好，定量下限为50 μg/kg，其余18种分析物的质量浓度均在1~15 μg/L范围内线性关系良好，定量下限均为10 μg?kg-1，相关系数均大于0.996，平均加标回收率为68%~105%，相对标准偏差为0.81%~15%。该方法简便、可靠、稳定，可用于茶叶中多种农药残留的快速检测与确证。

Abstract

A multiresidue method was developed for the simutaneous determination of 19 pesticides in tea by LC-MS/MS. The ionisation mode used was positive mode with multiple reaction monitoring．The one precursor/two product ion transitions were used for each neonicotinoids． The procedure，based on QuEChERS prior to the determination by UPLC-MS/MS，was validated based on the SANCO European Guidelines with satisfactory spiked recovery （68%–105%） and measurement uncertainty （≤20%）. The results showed that the calibration curves were linear in the range of 1-15 μg/L for 18 analytes and 5-75 μg/L for difulubenzuron．The limits of quantitation （LOQ） were 50 μg?kg-1 for difulubenzuron and 10 μg?kg-1 for the other 18 pesticides. The method was simple，rapid and accurate，and could meet the requirement of the maximum residue limits （MRLs） for pesticides in tea as recommended by the European Union.
