摘要
本文报导了只经一次沉淀分组直接用ICP-AES测定天青石中主量和次量元素锶,钙、铁、镁、锰、锌、钡和硅的分析方法。讨论了基体元素锶及钙对钡和锌的干扰效应。拟定的方法简便,快速。分析结果与经分离的ICP—AES法和常规法分析结果吻合。氧化锶含量为54.34％时,相对标准偏差0.35％。
A method for the analysis of celestite by ICP-AES is described. The sample was decomposed by Na2CO3 fusion and leached with water. The major and minor elements Sr,Ca,Si,Fe,Mg,Mn,Zn and Ba were determined separately in the residue and filtrate. Spectral interference from the matrix Sr and Ca in the determination of Ba and Zn was discussed. The precision of the method was found to be 0.35%(RSD,SrO 54.3%).
