【Abstract】 [Aims] The HPLC method for determination of sulfotep in technical organophosphorus pesticide was established. [Methods] The sample was separated and analyzed quantitatively with external standard method by Amethyst silica chromatography column at 30 ℃ with a UV-detector at 210 nm using n-hexane and tetrahydrofuran(THF)(99.5:0.5,by vol) as mobile phase at a flow rate of 1.0 mL/min. [Results] The linear relationship coefficient was0.999 8 with the standard deviation was between 0.01 and 0.02. In addition,the variation coefficient ranged from 0.49 to 2.60% with the average recovery of 99.4%. [Conclusions] The method is simple,rapid and accurate,which has good linear correlation.更多还原
