摘要
目的研究生活饮用水中环氧氯丙烷的检测方法,满足《生活饮用水卫生标准》的要求以及实际水质检测的需求。方法生活饮用水中环氧氯丙烷经过有机溶剂萃取,萃取液浓缩后,高弹石英毛细管柱分离,用具有ECD的气相色谱仪测定。结果该方法RSD均<10%,加标回收率为84.4%～105.4%,最低检出限为0.000 2 mg/L。结论该方法比国家标准方法中经过填充柱分离,用FID检测器检测生活饮用水中环氧氯丙烷灵敏度高,能满足《生活饮用水卫生标准》的要求以及实际水质检测的需求。
Objective To study a detection method for epichlorohydrin in drinking water in order to meet the requirement of drinking water standards（GB 5749-2006）.Methods Epichlorohydrin in drinking water was extracted by organic solvent,and concentrated liquid was separated by high elastic quartz capillary column,gas chromatography with ECD was used to determine epichlorohydrin.Results RSD was below 10%,recovery rate was 84.4%-105.4%,minimum detection limit was 0.000 2 mg/L.Conclusion The method is more sensitive than national standard method,it can satisfy the requirements of national standards（GB 5749-2006）.
