| Abstract: | A gas chromatography-negative ion chemical ionization mass spectrometry(GC/MS-NCI) was developed for the rapid determination of endosulfans and its metabolite in soil samples.The soil sample was pretreated with n-hexane and then analyzed by(GC/MS-NCI).External standard calibration was used;the selective ions of endosulfan and endosulfan sulfate were m/z 406,408,404,372 and m/z 386,384,352 respectively.The detection limit was 0.02~0.03 μg/kg.The recoveries were in the range of 83.6%~86.4% with the relative standard deviations less than 5%.The method proposed is efficient,accurate and sensitive,which could meet the requirements for determining endosulfans in soil. |
