ICP-AES法测定混合稀土金属及其化合物中的11个非稀土元素

Determination Method for Non-Rare Earth Elements in Mixed Rare Earth Metals and Compounds

采用全谱直读等离子光谱法测定混合稀土金属及其化合物中的钙、镁、铁、锌、铜、锰、镍、锶、钡、钴、铬,系统考察了不同基体及共存杂质元素对测定元素的影响,进行了加料回收及精密度实验,并用不同测定手段进行了比对实验。此方法准确、快速。

This paper uses ICP-AES methods to detect Ca ,Mg, Fe, Zn, Cu, Mn, Ni, Sr, Ba, Co and Cr in mixed rare earth metals and compounds, research the effects of different matrix and coexisting impurity elements, test the recovery rate and precision experiment, and compare the results of different determination methods. This method is rapid and accurate.
