自来水中一般都经过加氯消毒处理,这过程中使得水中有机卤化物的种类和含量增加,其中以氯化代烷(氯仿、四氯化碳)较高。这些都具有致癌性,因此对其含量的测定和限值的研究引起人们广泛关注。本方法采用了毛细管柱、电子捕获检测器对水中的氯仿、四氯化碳进行测定,取得了较满意 Tap water is generally subjected to chlorination, which results in an increase in the types and amounts of organic halides in the water, of which chlorinated alkanes (chloroform, carbon tetrachloride) are higher. These are carcinogenic, so the determination of its content and the limit of the study aroused widespread concern. This method uses a capillary column, electron capture detector for the determination of chloroform in water, carbon tetrachloride, and achieved satisfactory
