摘要
本文介绍了9种有机磷农药在黄瓜中的残留检测方法,选用VarianCP-3800气相色谱仪,DB-170130m×0.53mm×1.0μm毛细管柱,脉冲火焰光度检测器(PFPD)。采用加标法(添加水平为0.05、0.50、5.00mg/kg)测定了这些有机磷农药的回收率,其平均回收率为85.6%~110.0%,变异系数<20%。该方法的测定结果满足农药多残留的检测要求。
The residue analytical method for 9 organic phosphorus pesticides in cucumbers was introduced in this paper. The Varian CP-3800 gas chromatography was used with DB-1701 ( 30m ×0.53mm ×1.0μm) capillary column, pulsed flame photometric detector (PFPD) and extermal standard. The results showed that the average recoveries were 85.6%-110.0%, the coefficient of variation was smaller than 20%. The method met the requirements of pesticide residual analysis.
