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 two- valence magnesium into three - valence magnesium. For the molar density coefficient of three - valence, the photometric determination of high content magnesium is available.
