摘  要：
试验比较了快速溶剂萃取(ASE)和高速匀浆提取,固相萃取净化(SPE)和凝胶色谱净化(GPC),气相色谱(GC)和气质联用(GC-MS)检测对茶叶中农药残留,建立了茶叶中32种农药残留的检测方法,其中包含了相关标准规定的茶叶所需检测的14种农药、增加了13种高毒农药和5种菊酯类农药。样品采用两种方法提取,两种方法净化,两种仪器检测分析,分别做添加回收试验。结果表明:在0.10 mg/kg添加浓度下作添加回收试验,回收率和相对标准偏差分别为:一般提取和固相萃取净化81.00%～119.80%、1.10～5.42;一般提取和凝胶色谱净化76.47%～93.45%、3.43～7.34;ASE快速萃取和固相萃取净化80.12%～110.30%、1.37～5.32;ASE快速萃取和凝胶色谱净化76.45%～93.56%、2.56～7.98。MDL分别为MSD在0.079～14.40μg/kg、FPD/ECD在0.24～98.0μg/kg。该研究讨论的几种方法组合都具有高灵敏度、快速、准确度高、线性范围宽等优点,可满足茶叶中农药检测的要求。

摘  要：
The samples were extracted by Accelerated Solvent Extraction(ASE) and high-speed homogenate extraction,and purified by Solid Phase Extraction(SPE) and Gel Permeation Chromatography(GPC),then determined by Gas Chromotography-Mass Spectrometry(GC-MS) and Gas Chromatography(GC).This paper focused on the method for determination of residues of 32 kinds of pesticides,in which 14 kinds are need to detection in tea product,and 13 kinds are high toxic pesticides and 5 kinds are dimethrin pesticides.Two extracting methods,purifications,and,detection by two instruments are used on every sample,meanwhile,recovery testings are provided respectively.The result showed that when the concentration of spike was 0.10 mg/kg,the recoveries and RSD were: 81.00%～119.80% and 1.10～5.42 as general method extraction and SPE purification used;76.47%～93.45% and 3.43～7.34 as general extraction and gel chromatography purification used;80.12%～110.30% and 1.37～5.32 as ASE rapid extraction and SPE purification used;76.45%～93.56% and 2.56～7.98 as ASE rapid extraction and gel chromatography purification used.The Method Detection Limit(MDL) were MSD in the range of 0.079～14.40 μg/kg and FPD/ECD in the range of 0.24～98.0 μg/kg.The combinations of different means in this paper contains the advantages of high-sensitivity,high precision,rapidity,and wide linearity,which meet the determination of pesticide multi-residues in tea.
