快速溶剂萃取气相色谱法测定蔬菜中六六六和滴滴涕的残留量

Determination of BHC and DDT Residues in Vegetable by Gas Chromatography with Accelerated Solvent Extraction

建立了蔬菜中六六六和滴滴涕残留量快速溶剂萃取气相色谱的分析方法。该法的α-六六六、β-六六六、γ-六六六、δ-六六六、PP'-滴滴伊、OP'-滴滴涕、PP'-滴滴滴、PP'-滴滴涕检出限均≤0.05μg/L。加标回收率为88.6%—101.1%,相对标准偏差(RSD)小于8%。该法步骤简单快速,适用于蔬菜中六六六和滴滴涕农药的快速检测。

The method for determination of BHC and DDT residues in vegetable by gas chromatography（GC） with accelerated solvent extraction was established.The detection limits of alpha-BHC,beta-BHC,gamma-BHC,delta-BHC,PP’ -DDE,OP’ -DDT,PP’ -DDD,PP’ -DDT were all not more than 0.05μg/L.The recoveries of standard addition ranged from 88.6%to 101.1%with relative standard deviations（RSDs） less than 8%.The method is simple,rapid,and is readily applicable to rapid detection of BHC and DDT pesticide in vegetable.
