应用毛细管色谱(Capillary Gas Chromatography. CGC)对我国稻区取代六六六的12种残留水平的有机磷农药进行一次性快速分离定性,峰高外标法定量,平均检测极限为0.2ng,回收率为99.94%±3.23%,变异系数为3.18%。本法灵敏度较高,准确、重演性好,适用于多种有机磷农药的检测。 Capillary Gas Chromatography (CGC) was used to characterize 12 kinds of residual organophosphorus pesticides which were used to replace HCH in rice growing areas in China. The peak external standard method was used for quantitative determination. The average detection limit was 0.2 ng. The recovery rate Was 99.94% ± 3.23%, the coefficient of variation was 3.18%. This method has high sensitivity, accurate, good repeatability, suitable for the detection of a variety of organophosphorus pesticides.
