摘要
以V（正己烷）：V（丙酮）=1：1为提取剂，采用超声提取、毛细管柱气相色谱法测定了土壤中敌敌畏、甲拌磷、乐果3种有机磷及阿特拉津农药残留。结果表明：该方法的回收率为80．2％-93．9％，相对标准偏差为3．81％～8．79％，检出限为0．35～0．45μg／kg。
A capillary gas chromatography for determining atrazine residue and residual organophosphorus of three kinds of organopbosphorus pesticides in soil, diehlorvos, phorate and Rogor, was established. These residues were extracted with hexane/acetone （1：1, V/ V） by ultrasound extraction. The method is of wider range of application and better results. Recovery of the method is 80.2 %--93.9 %, RSD is 3.81%--8.79%, and detection limit is 0.35--0.45 μg/kg.
