摘要： 目的建立一种同时测定透析用水中多种微量元素的方法。方法以Rh、Ir 为内标，采用电感耦合等离子体-质谱法(ICP-MS)同时测定透析用水中As、Ag、Ba、Cr、Cu、Cd、Pb、Se、Sn、Zn10 种微量元素。结果本方法的线性范围宽，灵敏度高，线性相关系数均不低于0.999，相对标准偏差在1.28%-5.69%之内，各个元素的加标回收率在97.4%-100.9%之间。结论本方法准确、快速、便捷，能为透析用水安全提供有力保障。

Abstract: Objective To establish a method for the determination of several trace elements in dialysis water. Methods Inductively coupled plasma mass spectrometry was applied to determine trace elements in dialysis water by using Rh and Ir as internal references. Results The experimental results showed that this method had a broad linear range and high sensitivity with the linear correlation coefficients greater than 0.999. The relative standard deviations were in the range of 1.28% 5.69%, and the recoveries of added standards were in the range of 97.4%～100.9%. Conclusion This method is sensitive, rapid and accurate, useful for the strong assurance for dialysis water quality.
