| 摘 要： | 采用超高效液相色谱-电喷雾串联四级杆质谱仪（UPLC-ESI-MS/MS），于多反应监测（MRM）模式下建立了茶叶中灭多威、啶虫脒等8种杀虫剂残留的定性及定量分析方法。样品经纯水浸润，乙腈振荡提取，茶叶TPT萃取柱净化，BEH C18柱分离，超高效液相色谱-串联质谱仪测定。结果表明:在0.001~0.5 mg/L质量浓度范围内，各农药峰面积与进样质量浓度间均呈良好的线性关系（r>0.990），检出限（LOD）为0.000 3~0.01 mg/kg；在国家相关标准规定的添加浓度水平下，各待测农药的平均回收率在61%~107%之间，相对标准偏差（RSD，n=6）为0.2% ~9.9%。该方法准确、可靠、灵敏度高，适用于茶叶中灭多威、啶虫脒等8种杀虫剂残留的检测。

| Abstract: | A method of ultra performance liquid chromatography-electrospray tandem mass spectrometry(UPLC-ESI-MS/MS) in multiple reaction monitoring(MRM) mode was developed for the qualitative and quantitative analysis of eight insecticide residues in tea.The sample preparation was based on pure water soak,oscillatory-assisted acetonitrile extraction,TPT-SPE cleanup,BEH C18 column separation and UPLC-MS/MS determination.The method showed a good linearity(r>0.990) between concentrations of 0.001-0.5 mg/L,with LODs of 0.000 3-0.01 mg/kg.Following the fortified levels based on relevant national standard,the average recoveries of this method were from 61% to 107%,and the relative standard deviations(RSD,n=6) were from 0.2% to 9.9%.The method was shown to be reliable,accurate,sensitive and appropriate for the determination of eight insecticide residues in tea. |
