摘要

GB/T 5009.20中果蔬中有机磷农残检测的改进实验,浸提溶剂由丙酮和二氯甲烷改为乙腈,并缩减样品和试剂,HP-5毛细管柱分离,FPD检测器,外标法定量,实验表明,该方法回收率90.2%～96.8%,相对标准偏差0.26%～0.36%,精密度良好。
        This experiment establish a simplified method for detecting of organ phosphorus pesticide residues in GB/T 5009.20. Extraction solvent is changed from acetone and dichloromethane to acetonitrile, and the number of sample and reagent are reduced. HP-5 capillary column is used to separate, FPD detector and external standard method are used for quantification. The experimental results show that the recovery rate of the method is in the range of 90.2%～96.8%, the relative standard deviation is in the range of 0.26%～0.36%, the precision is good.
