ICP-AES测定钾石盐中钾、钠、钙和镁的含量

Determinations of K,Na,Ca and Mg in Sylvite by ICP-AES

在选定的最佳条件下,样品直接溶解后采用ICP-AES测定钾石盐中钾、钠、钙、镁的含量,其最终检测结果与化学法测定结果一致。该方法简便、快速、线性范围宽、测量稳定、可多元素同时测定。回收率为98.3%—100.2%。

Under the optimal conditions,the sample was dissolved,and the amounts of K,Na,Ca and Mg in sylvite samples were determined by ICP-AES. This method is simple,rapid and broad linear range,stable determining,the recovery of 98.3 %-100. 2%. The test results are accordant with those of chemical method.
