摘　　要：用电感耦合等离子体质谱法测定生活饮用水和地表水中的铊元素,该方法不需要进行繁琐的分离富集等预处理,也避免了光谱干扰,十分简便、快速。结果表明,该元素的检出限为7.0×10-4μg/L,加标回收率在95-102%,对质控样品平行测定6次,相对标准偏差为0.6%,完全满足对生活饮用水和地表水进行铊元素分析的要求。The Thallium was determined by using Inductively Coupled Plasma-mass Spectrometry in drinking water and source water.We need not to do many steps of separation and enrichment,and avoided spectral interference by using this method.The experiment results showed that ICP-MS method was high sensitive degree,low detection limit and it was simple,rapid,so it can help us work efficiently.The detection limit of Thallium was 7.0×10-4μg/L,the recovery standard addition was 95-102%,the RSD（n=6） was 0.6%,so this method can meet the testing requirements of the standards for water quality.
