摘要
目的:建立电感耦合等离子质谱法(ICP-MS)测定水中12种金属离子的检测方法,了解渔沙坦地区水质状况。方法:样品直接用ICP-MS测定,用混合内标校正基体干扰和漂移。结果:本方法的检出限介于0.017μg/L^0.229μg/L,精密度小于5.6%,样品加标回收率可达92.0%~106.9%,对标准参考物质分析结果令人满意。结论:该方法简便、快速、准确,可用于水中12种金属离子的同时测定。
Objective： To establish a method for determination of 12 kinds of metals in water by inductive cou- pled plasma - mass spectrometry （ ICP - MS） and investigate the water quality of Yushatan area. Methods： The samples were measured and quantified by ICP - MS directly, with internal standard to adjust the matrix interference and drift. Results： The detection limit of the method was between 0. 017 μg/L and 0. 229 μg/L, with the relative standard deviations （RSD） blow 5.6% and the recoveries of 92.0% - 106.9%. The analysis results of standard reference materials was satisfactory. Conclusion： This method is proved to be simple, fast and accurate, it can be used to determine 12 kinds of metals in water simultaneously.
