摘要
通过对萤石中CaF2的原分析方法的研究,找出其中的不足,确定了导致CaF2分析结果偏低的三个主要因素:Ca的总量的测定、CaCO3的测定以及EDTA标准滴定液的标定,结合国家标准分析方法,对我们正在使用的分析方法进行改进,以解决这些问题。探讨出萤石中CaF2的较为准确的分析方法,提高了萤石分析的准确率。
By researching the original analysis method for CaF2 in fluorspar,this paper discovered its shortcomings,determined three main factors for causing CaF2 analysis results to be lower slightly:determination of total Ca contents,determination of CaCO3 as well as calibrating of EDTA standard titration solution.According to the national standard analysis method,we improved the analysis method which is being used by us so as to solve these issues.This paper obtained more accurate method for CaF2 analyzing in fluorspar.This analysis method enhanced the test accuracy of fluorspar analyzing.
