摘　　要：目的：建立电感耦合等离子体质谱（ICP-MS）简便、快速、准确的测定水中10种元素的分析方法，了解广州市水质概况。方法：样品直接用ICP-MS进行分析，用混和内标校正基体干扰和漂移。结果：整个方法的检出限介于0．014-1．043μg／L，精密度优于5．8％，回收率介于93．0％-110．0％。对标准参考物质的分析结果令人满意。结论：该方法简单、快速和准确，能适用于水中10种元素的同时测定。Objective：Developing a simple, rapid and accuracy method to determination of 10 trace elements in water by inductively coupled plasma mass spectrometry, and realizing the status of water quality in Guangzhou. Methods ： The sample was determined directly by inductively coupled plasma mass spectrometry which used mixed internal standard to correct matrix interference and signal drifting. Results ：The range of detection limit of observed 10 elements was from 0. 014 μg,/L to 1. 043 μg,/L, the RSD were less than 5.8%, recoveries were 93.0% - 110.0%, the results of analyzing standard materiel were satisfactory. Conclusion：This method is simple , rapid and accuracy, and can be used to determine 10 trace elements in water simultaneously.
