[Aims]This study aims to establish a method to determine the related impurities of malaoxon in malathion EC.[Methods]The qualitative analysis and quantitative analysis of malaoxon was determined by GC-MS.[Results]The recovery of the method was between 99.4％and 111.0％,the RSD was 3.0％,and the linearity correlation of malaoxon was good between 0.972 and 29.16 mg/L.The limit of detection(3S/N)was 0.32 mg/L.[Conclusions]The method is relatively simple,which is suitable for industrial control analysis and can meet the limit control of malaoxon in malathion EC and TC.
