| 摘 要： | 对氧化还原滴定计算分析法同时测定Ce^4 与Fe^2 进行了研究。以铂电极为指示电极，在Fe^3 存在的条件下，用Ce^4 溶液滴定Fe^2＋溶液，可同时求出Ce^4 与Fe^2 的浓度。讨论了Fe^3 浓度对测定结果的影响。

| Abstract: | The simultaneous determination of Ce 4+ and Fe 2+ has been studied by calculating analysis of oxidation-reduction potentiometric titration using platinum electrode as the indicator electrode. The concentration of Ce 4+ and Fe 2+ can be determined simultaneously when Fe 2+ is titrated by Ce 4+ in the existence of Fe 3+ . The effect of Fe 3+ concentration on the titration has also been discussed. |
