摘　　要：采用气相色谱质谱联用技术(GC/MS),对乙酰甲胺磷、甲胺磷在青油菜中的残留分析方法进行了研究。结果表明,当青油菜中两种农药的添加质量分数为0.02、0.1、1mg/kg时,乙酰甲胺磷的回收率为82.9%～90.6%,变异系数为4.71%～5.77%;甲胺磷的回收率为85.1%～90.4%,变异系数为3.89%～5.21%。方法的灵敏度、精密度和检测限都符合农药残留分析规范的要求。A method was developed to determine residue of acephate and methamidophos in rape plants by GC/MS. The average recoveries of acephate at the spiked amount of 0.02, 0.1, 1.0 mg/kg was 82.9-90.6% and the coefficient of variation was 4.71-5.77%. The average recoveries of methamidophos at the spiked amount of 0.02, 0.1, 1.0 mg/kg was 85.1-90.4% and the coefficient of variation was 3.89-5.21%.
