The potassium permanganate content in oxidized solution was determined by iodometry method.The accuracy and precision of this way was confirmed by test of the relative standard deviation (RSD).The RSD of the determination result is 0.24％,which indicates that the method is sample and correct.The recovery ratio was proved by adding standard potassium permanganate solution into the sample solution.The recovery of this analysis method is 99.48％ ～ 103.22％ which can achieve the analysis request.%用碘量法分析钢铁氧化处理槽中高锰酸钾的含量,计算分析结果的相对标准偏差确定该方法的准确度和精密度,分析结果的相对标准偏差为0.24％,本方法简单且准确.通过在样品中加入高锰酸钾标准溶液来测定回收率,该分析方法的回收率在99.48％～103.22％之间,达到分析要求.
