| 摘 要： | 天青石矿的主要成分是硫酸锶,其中含有一定量的硫酸钡、碳酸钙。由于锶、钙、钡均是碱土金属元素,其性质非常相近,分析测定时极难分离,存在相互干扰。对测定天青石中锶、钙、钡的3种常用方法进行了比较研究,结果表明,容量法具有较高的回收率,X-射线荧光光谱法具有较好的精密度,而电感耦合等离子体原子发射光谱法(ICP-AES)在测量微量元素方面具有很大的优势。

| Abstract: | The celestite ore mainly consists of strontium sulfate,barium sulfate and calcium sulfate.The strontium,barium and calcium are difficult to separate from each other,because all of them belong to alkaline earth metallic elements and their characteristics are quite alike.Three determining methods of strontium,barium and calcium content in celestite were compared in this paper.The results showed that volumetric method has high recovery,X-ray Fluorescence Spectrometry has high precision,and inductuvely coupled ... |
