| 摘 要： | 建立了一种基于气相色谱-离子阱二级质谱(GC-MS/MS) 检测茶叶中亚胺硫磷、噻嗪酮和哒螨灵残留量的方法.样品采用乙腈提取后经活性炭小柱净化，浓缩，定容后上机分析.采用HP-5MS毛细管柱分离，电子轰击电离源二级质谱监测模式检测，外标法定量.方法的线性关系良好(R不低于0.9970)，检出限在0.01 ～0.02 mg/kg之间，3种农药添加回收率在92.0%～115.0%之间，RSD在3.0%~9.3%，方法操作简单，灵敏度高，可作为茶叶中3种农药残留量的同时测定方法.

| Abstract: | A qualitative and quantitative analytical method was developed for the determination of buprofezin,fosmet and pyridaben by solid phase extraction on gas chromatography-ion trap mass spectrometry in tea.The separation and quantitative analysis of 3 pesticides was performed by the gas chromatography-ion trap mass spectrometry.The results showed that recoveries of 3 pesticides ranged from 92.0% to 115.0%.The detection limits were in the range of 0.01~0.02 mg/kg.The method is simple,and is of high efficiency an... |
