【摘要】 在农业部标准NY/T 76 1- 2 0 0 4的基础上 ,对蔬菜中甲胺磷、毒死蜱、对硫磷和氯氰菊酯 4种农药残留的测定方法进行了改进。改进后的方法与原方法相比节省溶剂约 6 0 % ,节省时间约 5 0 %。甲胺磷、毒死蜱、对硫磷和氯氰聚酯的加标回收率分别为 6 7.3%～ 92 .5 %、95 %～ 10 5 %、91.2 %～ 10 7.5 %和 86 .2 %～ 10 6 .2 %。更多还原

【Abstract】 The method for the determination of methamidophos, chloropyrifors, parathion and cypermethrin in vegetable by GC-MSD was improved based on the standard method NY/T 761-2004. Reagent is saved 60% and time is saved 50% compared with the standard method. The recoveries of methamidophos, chloropyrifors, parathion and cypermethrin are 55.7%～99.5%, 95.2%～105.0%, 91.2%～107.5% and 86.2%～107.6% respectively.更多还原
