中文摘要: 建立高效液相色谱-柱后衍生测定蔬菜中6种氨基甲酸酯类农药残留的方法。样品中的氨基甲酸酯类农药经乙腈溶剂超声提取后，CARB/NH2固相萃取柱净化，高效液相色谱-柱后衍生法进行定量分析。结果表明在一定浓度范围内质量浓度与峰面积有良好的线性关系，其线性相关系数为0.999 2～0.999 8，加标回收率在79%～91%之间，相对标准偏差（RSD）为0.8%～4.9%，方法检出限为0.002mg/kg～0.005mg/kg。
Abstract:A method for the determination of 6 kinds of carbamate pesticides in vegetables by high performance liquid chromatography with post column derivatization was established.After ultrasonic extraction of the carbamate pesticides in the sample，CARB/NH2was extracted by acetonitrile and purified by solid phase extraction column，and then the quantitative analysis was carried out by high performance liquid chromatography and post column derivatization.The results showed that the concentration and the peak area presented a good linear relationship，with the linear correlation coefficient of 0.999 2-0.999 8.The recovery rate was between 79%and 91%，while the relative standard deviation（RSD）was 0.8%-4.9%，and the detection limit of the method was 0.002mg/kg-0.005mg/kg.
