提出了间接碘量法测定高铁酸钾样品中常量、高含量高铁酸钾的方法。用碱性碘化钾溶液(pH 11~12)溶解高铁酸钾试样,调节溶液的pH值为1,反应40 min后,以硫代硫酸钠标准溶液作为滴定剂进行滴定。方法用于高铁酸钾样品的分析,测定结果与亚铬酸盐法测定值相符。

A method of iodometric method for the determination of macro-amount or high-amount of potassium ferrate was proposed. Sample of potassium ferrate was dissolved in KI solution (pH 11-12), and pH values of sample solution was adjusted to 1. After 40 min, the above solution was titrated using sodium thiosulfate standard solution as titrant. The proposed method was applied to the analysis of potassium ferrate, and results obtained were in conformity with those obtained by the method of chromite titration.
