摘　　要：本研究建立了动物源食品中莠灭净残留量的气相色谱检测法。样品以乙腈为提取溶剂,提取液以酸性氧化铝柱净化,乙腈-甲苯(7∶2,V/V)洗脱,以气相色谱火焰光度检测器(GC-FPD,S型滤光片)检测,外标法定量。方法的准确度与精密度较好,检出限为0.005mg/kg,平均添加回收率在88.1%～102.8%之间,相对标准偏差(RSD)为3.07%～8.29%,满足农药残留分析的要求。A method has been developed for the determination of ametryn residue in animal-derived food by gas chromatography. Acetonitrile was the optimal solvent to extract ametryn in animal-derived food. The cleanup was conducted by SPE on a Alumina-A cartridge. Then acetonitrile-toluene（7：2,V/V） was used to elute ametryn residue. Under the selected analytical conditions,the detection limit was 0.005 mg/kg. The average recoveries were from 88.1% to 102.8%. RSD values were from 3.07% to 8.29%.
