【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.更多还原
