摘　　要：建立了液液萃取气相色谱法测定饮用水中一氯二溴甲烷的方法。文中采用正已烷萃取水中一氯二溴甲烷,用DB-5毛细管柱分离,电子捕获检测器检测的方式进行气相色谱分析。该方法操作简便,灵敏度高,检出限低,具有较好的准确度和精密度,可用于生活饮用水中一氯二溴甲烷的测定。A method for the determination of chlorodibromomethane in drinking water by using liquid liquid extraction-gas chromatography was established. In this paper,chlorodibromomethane in the water was extracted by n-hexane and separated by DB-5 capillary column,and the detection method of electron capture detector was analyzed by gas chromatography. This method was easy to operate,with high sensitivity,low detection limit,good accuracy and precision. So the method the be used for determination of chlordibromomethane in drinking water.
