中文摘要	应用液相色谱-电喷雾电离三级四极杆质谱(LC-ESI-MS/MS)方法测定茶叶中呋虫胺、噻虫嗪、噻虫胺、吡虫啉、啶虫咪和噻虫啉烟碱类农药残留.前处理方法包括添加同位素内标吡虫啉-D4,乙腈提取,再用活性碳和Oasis(HLB)固相小柱净化.该方法采用正离子方式,多反应监测每种烟碱类杀虫剂各两对离子进行定性、定量分析.方法在0.01～0.4 mg/kg范围内具有良好的线性关系.实验了3个添加水平0.02、0.04和0.2 mg/kg,回收率范围为80.1%～106.1%;相对标准偏差小于9.7%;方法检出限(LOQ)均为0.02 mg/kg.本方法简便、快速、准确,各项技术指标满足国内外法规的要求,可用于茶叶样品中烟碱类农药残留的确证检测.
英文摘要	A method for the determination of dinotefur,thiamethoxam,clothiandin,imidacloprid,acetamiprid and thiacloprid in tea samples was introducted.The isotope internal standard(imidcacloprid-D4) was added into the sample solutions.The sample was extracted with acetonitrile.Then it was cleaned up with active charcoal and Oasis(HLB) columns.The ionisation mode used was positive mode with multiple reaction monitoring.The one precursor/two product ion transitions were used for each neonicotinoids.The results show that the working curves were linear in the range of 0.01-0.4 mg/kg.The recoveries were between 80.1%-106.1% and the relative standard deviations were less than 9.7% at the spiked levels of 0.02,0.04 and 0.2 mg/kg.The limits of quantitation were 0.02 mg/kg.The method is simple,rapid,and accurate,and its performance can meet the requirements of the domestic and international legislation.The method adapts to confirm residues of neonicotinoid pesticides in tea samples.
