引言明矾石中常混杂大量的硅酸盐,一般沿用硅酸盐的经典方法进行分析,手续繁杂,倘掌握不当或操作不够熟练,时常不易得到满意的结果,而且一个矿样的全分析需要10个工作日以上的时间始能完成。为满足科学研究工作及生产大跃进的要求,特对明矾石快速分析法进行介绍。明矾石快速分析法,包括矿样的分解及二氧化硅、硫酸根、氧化钾、三氧化二铁和二氧化钛六个项目的测定,每一个矿样的全分析可于6～8小时以内完成。本法系根据Hadley等的比色测定硅的方法,Hirano等的离子交换测定硫的方法,Cluley等的四苯硼
Introduction Alunite often mixed with a large number of silicate, silicate generally followed the classic method of analysis, complicated procedures, if not properly mastered or not skilled enough to obtain satisfactory results often, and a mineral sample analysis requires 10 Work more than the beginning of the time to complete. In order to meet the scientific research work and the requirements of the Great Leap Forward in Production, a rapid analysis of alunite is introduced. Alunite rapid analysis method, including the decomposition of mineral samples and the determination of six items of silica, sulfate, potassium oxide, ferric oxide and titanium dioxide. The complete analysis of each sample can be completed in 6 to 8 hours. This method is based on Hadley’s method of colorimetric determination of silicon, Hirano ion exchange method for the determination of sulfur, Cluley et al tetraphenyl boron
