Abstract: Objective:To establish a method for determination of 14 kinds of volatile halogenated hydrocarbons including 1,1-dichloroethene,dichloromethane,trans-1,2-dichloroethene,chloroprene,cis-1,2-dichloroethene,trichloromethane,tetrachloromethane,1,2-dichloroethane,trichloroethene,bromodichloromethane,tetrachloroethene,dibromochloromethane,tribromomethane,hexachloro-1,3-butadiene in drinking water. Methods:The sample were automatically headspace balanced at 60℃ for 30 min before injection. The samples were separated by capillary chromatography column DB-624 and quantified by gas chromatography-mass spectrometry. Results:The linear relationship of 14 kinds of volatile halogenated hydrocarbons at different concentrations were good,and the correlation coefficient was 0.9950~0.9999. The recoveries were 95.75%~100.67% and the precisions were 0.41%~3.58%. Conclusion:The method is accurate and easy to determine the content of 14 kinds of volatile halogenated hydrocarbons in drinking water at one time.
