摘要
目的:研究生活饮用水中三卤甲烷定量快速分析方法。方法:水样直接进样,用毛细管柱色谱分离,电子捕获检测器检测,采用内标法定量,可同时测定水中三氯甲烷、一溴二氯甲烷、二溴一氯甲烷和溴仿。结果:三氯甲烷、一溴二氯甲烷、二溴一氯甲烷和溴仿最低检出浓度<1μg/L。准确度和精密度均符合检验要求。结论:方法快速、简便、准确。
Objective：To establish a faster GC quantitative analysis of trihalomethanes in drinking water. Methods：The method used direct sampling technique to determinate chloroform, bromodiehloromethan, dibromochloromethane, bromoform, which was seperated by tube column, detected by electronic capture detector and determined by inner standard method. Results：The detection limites of chloroform, bromodichloromethan, dibromochloromethane and bromoform were blow 1μg/ml. Conclusion： The method is proved to be rapid, simple and accurate.
