摘要/Abstract

摘要： 利用FPD检测器,建立了气相色谱法对植物性食品中对硫磷和甲基异柳磷含量快速测定的方法。结果表明,对硫磷和甲基异柳磷检出限均为2 μg/kg（进样量为1 μL,S/N=3）,对硫磷和甲基异柳磷样品加标回收率分别为86.7%~94.5%、89.3%~92.6%,对硫磷和甲基异柳磷相对标准偏差RSD（n=10）分别为3.86%、4.23%。

Abstract: A method was established for the determination of the content of parathion and isofenphos-methyl in plant food by gas chromatography. The method was validated by FPD detector, external standard method and automatic injection, the results showed that the detection limits of parathion and isofenphos-methyl were 2 μg/kg （1 μL, S/N=3）, the recoveries of parathion and isofenphos-methyl were 86.7%~94.5%, 89.3%~92.6%, the RSD（n=10） of parathion and isofenphos-methyl were 3.86% and 4.23% respectively.

Key words: external standard method, plant food, parathion, isofenphos-methyl
