摘要
采用KromasilC18反相柱为色谱柱,乙晴∶水=65∶35(v/v)为流动相,紫外检测器在210nm对农药乐果中间体-硫磷酯进行高效液相色谱分离和测定。其线性相关系数为0.9999,变异系数为0.1%,回收率为99.4%~100.4%。
A method for the determination of O, O-dimethyl-S- (methoxy-earbonymethyl) dithiophosphate by HPLC was described, with Kromasil C18 column (4.6 min×250 mm, 5 μm) , acetonitrile-water (65 : 35, v/v) as mobile phase and UV detection at wavelength 210 nm. The results showed linear relationship of 0.999 9, the variation coefficient of 0.1%, and the recovery of 99.4%-100.4%.
