摘要
硅酸锰分析研究得较少,现用的方法都是在系统物相分析中把最后残渣部分作为硅酸锰相的结果,存在着偏高或者偏低的缺点。本文提出用盐酸-二氯化锡为浸取剂室温浸出分离硅酸锰的新方法,除硅酸锰以外,其他锰矿物几乎都全部溶解,测定残渣中锰即为硅酸锰,方法快速,其他锰矿物的影响很小。
A new chemical phase analytical method is developed for analysis of manganece silicate in manganese minerals by making use of HCl+SnCl_2as selective solvent. Except manganese silicate this selective solvent can speedily dissolved all other manganese minerals at room temperature. The remaning manganese silicate then is dissolved and followed by determination by means of atomic absorptiometry or volumetry.
