摘要
目的:建立饮用水中多种卤代有机物的分析方法。方法:采用顶空气相色谱法测定饮用水中十三种挥发卤代烃。结果:在所建立的实验条件下多种卤代有机物的平均回收率在81.3%~104.7%之间,相对标准差(RSD)为1.52%~5.68%,检测限为0.025μg/L^8.4μg/L。结论:所建立的分析方法简便、快速、准确,可同时测定多种挥发性卤代烃。
Objective：Developing a method to determine the thirteen volatile halogenated hydrocarbons in drinking water.Methods： The thirteen volatile halogenated hydrocarbons in drinking water were determined by headspace capillary gas chromatography.Results： Under the optimal experimental conditions,the recoveries of the thirteen volatile halogenated hydrocarbons were in the range of 81.3%~104.7%,the relative standard deviations were from 1.52% to 5.68%,and the determination limited is between 0.025 μg/L～8.4 μg/L.Conclusion： The method we developed is rapid,simple and accurate.Using the method,a variety of volatile halogenated hydrocarbons could be determined simultaneously.
