摘　　要：对氧化还原滴定计算分析法同时测定Ce4+ 与Fe2 + 进行了研究。以铂电极为指示电极 ,在Fe3+ 存在的条件下 ,用Ce4+ 溶液滴定Fe2 + 溶液 ,可同时求出Ce4+ 与Fe2 + 的浓度。讨论了Fe3+The simultaneous determination of Ce4+ and Fe2+ has been studied by calculating analysis of oxidation-reduction potentiometric titration using platinum electrode as the indicator electrode. The concentration of Ce4+ and Fe2+ can be determined simultaneously when Fe2+ is titrated by Ce4+ in the existence of Fe3+. The effect of Fe3+ concentration on, the titration has also been discussed.
