摘要
本文首次提出了用ICP-AES法测定用D001-CC强酸型阳离子交换树脂预分离富集钨酸钠中Ca和Mg。Ca及Mg的平均口收率分别为95%及90%,相对偏差分别为1.8%及0.9%。
A new method for the determination of Ca and Mg by ICP-AES after separation with str-ong acidic cation resin has been proposed. The recoveries of Ca and Mg in the sample are 95%and 90% respectively. The relative standard deviations are 1.8 % and 0.9%' respectively.
