摘要：

目的：检测长白山天然矿泉水中锂、铍、铝、钒、锰、钴、镍、铜、锗、砷、硒、铷、钼、银、锡、铯、锑和钡18种微量元素的含量，为评价长白山天然矿泉水质量提供参考。方法：采集吉林省长白山靖宇县五龙泉、神龙泉、银龙泉和林海泉4处天然矿泉水，水样经酸化后直接采用电感耦合等离子体-质谱（ICP-MS）法进行检测。结果：被测元素的检出限为0.005~0.573 μg?L-1，除硒元素外，其他元素相对标准偏差为0.1%~4.5%，回收率为81%~116%；4处矿泉水中的18种微量元素含量均符合GB 8537-2008饮用天然矿泉水卫生标准。结论：ICP-MS方法检出限低，具有良好的准确度和精密度，适用于多种元素快速检测；长白山靖宇县4处天然矿泉水中18种微量元素含量均符合国家饮用天然矿泉水卫生标准。

Abstract:

Objective To detect the contents of 18 trace elements in natural mineral water in Changbai Mountain area,and to provide reference for evaluating the quality of natural mineral water of Changbai Mountain.Methods Wulong Sping,Shenlong Spring,Yinlong Spring and Linhai Spring were collected in Jingyu County of Jilin Province,the acidified water samples were analyzed by inductively coupled plasma mass spectrometry(ICP-MS).Results The detection limit was 0.005-0.573 μg?L-1,the relative standard deviation (RSD) was 0.1%-4.5% (except selenium),and the recovery rate was 81%-116%.The contents of 18 trace elements in the four natural mineral waters consistented with the national health standard of drinking natural mineral water (GB 8537-2008).Conclusion ICP-MS has a low limit,good accuracy and precision,which is suit for a rapid analysis of multielement.The contents of 18 trace elements in natural mineral waters of Changbai Mountain area consistent with the national health standard of drinking natural mineral water.
