摘要
利用ICP-MS法对饮用水中的15种稀土元素进行全定量分析。结果表明,ICP-MS法可同时测定饮用水中的15种稀土元素;方法具有下述优点:测定速度快,一个样品仅需2~3分钟;灵敏度高,方法检出限低,在0.0006μg/L^0.02μg/L范围内;精密度好,RSD小于2.23%;准确度高,加标回收率为92.6%~103%;线性范围宽,达到8~9个数量级。
Quantitative analysis of 15 kinds of rare earth in drinking water by ICP- MS, 15 kinds of lanthanide can be analyzed in drinking water at the same time. It takes about 2-3 minutes for every sample, the sen-sitivity is high, The detection limit is lower, in the range of 0.0006-0.02μg/L. The precision is very good, RSD is below 2.23%. and accuracy is high ,the recovery rate of added standard is between 92.6%~103%. The liner range is wide, 8-9 orders of magnitude.
