摘要
研究了将低价锰氧化成高锰酸根离子的条件 ,并确定了差示光度法测定高锰酸根离子 ,借此测定高含量锰的分析方法。该方法简单、快速 ,适用于电解二氧化锰、软锰矿及Li -MnO2 二次电池正极材料中总锰的测定 ,结果令人满意。
The requirements of Mn(Ⅱ) oxidized to MnO - 4 were studied and a method for measuring MnO - 4 by means of differential spectrophotometry was defined. This method was used to determine high content of manganese in some samples, such as manganese dioxide, pyrolusite with satisfactory results.
