摘要
利用碘量法基本原理 ,建立了一种快速测定软锰矿中二氧化锰含量的新方法。在优化后的测定条件下 ,其测定结果与标准值对照完全一致 ,相对标准偏差小于 0 15 %。此法简便、快速、准确可靠 。
Based on the theory of iodimetry,a new analytical method for the rapid titration of manganese dioxide in pyrolusite is developed.Under the optimized conditions,the determination results of the method are in good agreement with recommended values,the relative standard deviation is less than 0.15%. The method is simple, rapid, accurate and reliable. It can be used for the determination of manganese dioxide in pyrolusite.
