摘  要：
本方法采用丙酮水溶液(8+2)提取样品,提取液经二氯甲烷液-液分配、凝胶色谱柱(GPC)净化,固相萃取柱(活性炭)再净化,浓缩定容后,用气相色谱-质谱仪(GC-MS)测定,外标法定量。采用选择离子检测进行阳性确证。选择菠菜、柑橘等10种蔬菜水果为实验样品、敌敌畏等77种农药添加水平在0.05～2.00mg/kg时,该方法回收率为53.6%～124.8%;精密度为4.01%～24.90%;方法测定低限为0.01～0.200mg/kg。

摘  要：
One testing technology of determining 77 organophosphrous and carbamate pesticides residues in fruits and vegetables is developed. In this study, the samples are extracted with acetone and water (8+2). The extract is distributed with dichloromethane, and then is cleaned by passing through one gel permeation chromatography (GPC) column and one active carbon solid phase extraction (SPE) column in sequence. The eluate is condensed to a definite volume, and then determined and confirmed by gas chromatography - mass spectrometry(GC-MS) with external standard method. Ten vegetables and fruits including spinach and orange etc. are selected as samples. 0.05～2.00mg/kg of the 77 pesticides such as dichlorvos etc. are fortified into blank samples. The corresponding recoveries are 53.6%～124.8% and the precisions are 4.01%～24.90% and the limit of determination (LOD) are 0.01～0.100mg/kg.
