摘　　要：参照美国标准方法在国内建立了饮用水中氯消毒副产物三卤甲烷的液液萃取毛细管气相色谱测定方法,其检测限、加标回收率、精确度都达到美国标准方法的要求,好于国内顶空进样标准方法(GB5750-1985).并且以甲基叔丁基醚为萃取剂,改进了原方法的升温程序及用硫酸钠代替氯化钠,使测定方法具有准确性高、可靠、测定过程更简便等优点.The method for determination of halomethanes （THMs） has been established in China referring to The American Public Health Association, American Water Works Association and the Water Environment Federation （APHA -AWWA -WEF） standard method by liquid- liquid extraction and gas chromatography with electron- capture detection. The accuracy of the method presented in this paper is comparable to that of APHA - AWWA - WEF standard method method, excel Chinese national standard examination method GB5750 - 1985. Furthermore , the modification made to temperature program and used of methyl - ten -butyl ether（MTBE） as the extraction agent, replaced sodium chloride by sodium sulfate makes this method the advantage of high sensitivity, reliability and relative simplicity.
