摘　　要：对亚铁钼蓝光度法测定锰铁中硅时 ,合适的溶样酸、酸度及溶样时是否加高锰酸钾氧化碳化物的影响进行了研究 ,改进了传统的分析方法 。This paper studies the determination of silicon in ferromanganese by spectrophotometry The influnce of appropriate acid and acidity was examined and whether potassium permanganate is added to oxidize carbide in the prosess of dissolving sample was examined too We improved traditional analytical method and got a new method which is more suitabale for the determination of silicon in ferromanganese

关 键 词：钼酸盐 硫酸亚铁胺 锰铁 分光光度法 硅
