摘要
目的：建立简单快速有效的方法,测定饮用水中的挥发性有机物。方法：采用吹扫捕集-毛细管气相色谱法,对饮用水中13种挥发性有机物同时进行分离、定性和定量检测。结果：不同的化合物的平均回收率在98.5%-103%之间,相对标准偏差均小于6.0%,该方法的检测限在0.001-0.0001 mg/L。结论：吹扫捕集-毛细管色谱技术不经有机溶剂萃取和浓缩,减少了损失,具有灵敏度高,受干扰少,定性和定量准确,操作简单等特点。
Objective：To establish a method for the simple and rapid detection of volatile organic compounds.Methods：Thirteen kinds of volatile organic compounds in water were separated,qualitatively and quantitatively detected simultaneously by using purge and trap gas chromatography.Results：The average recovery rate was between 98.5%～103%,the RSD less than 6.0%,and the detection limit of this method 0.001～0.0001 mg/L.Conclusion：This method is sensitive,accurate and simple.
