稀土镧、铈、钕分析方法研究

A Study of Analysis Methods about Rear Earth Elements:Lanthanum, Creium and Neodymium

针对冕宁稀土矿组成的特点，对稀土元素镧、铈、钕的分析方法进行了研究，确定了在普通实验室内定性和半定量测定镧、铈、钕的方法和定量测定稀土元素总量的方法，为冕宁稀土矿的深加工分析提供了一套完整的快速、简便方法。

The analysis methods of rear earth elements lanthanum, cerium and neodymium in Mianning rear earth ore have been studied. The qualitative analysis methods and semi-quantitative analysis method about the three elements and quantitative analysis method about the total quantity of all rear earth elements have been found, which are simple,convenient and practical.
