| 摘 要： | 以亚铬酸盐氧化还原反应为基础建立了高铁酸钾的滴定分析方法，对滴定分析条件进行了优化研究，结果表明，用碱度为11～12M的亚铬酸盐溶液测定高铁时，测定结果稳定，与用亚砷盐酸法测的结果一致，方法简便、快速、准确，与亚砷酸盐法相比，该法特别适合于低浓度的高铁酸钾溶液的定量分析。

| Abstract: | A method for the determination of potassium ferrate(VI) based on the oxidation of chromite was introduced in this paper. Investigation to determine the optimum alkalinity of the chromite solution used in the determination of potassium ferrate(VI) showed that consistent results were obtained by using chromite solutions with hydroxyl ion of 11 to 12 mol/L. The method is rapid, simple and accurate. This method, compared with the previously reported arsenite method, is particularly suitable for the analysis of dilute solutions of ferrate(VI) ion. |
