摘要
在磷酸介质中，于220℃温度下，用高氯酸将二价锰氧化为三价锰，因三价锰离子的摩尔浓度系数远较七价锰离子的小，借此可做高含量锰的光度法分析。
In phosphoric acid medium, below the temperature of 220℃, to use chloric acid to oxygenate twovalence magnesium into three-valence magnesium. For the molar density coefficient of three-valence magnesium is much smaller than that of the seven-valence, the photometric determination of high content magnesium is available.
