Improvement of Analysis Method of Manganese Dioxide
摘要/Abstract
摘要:
在草酸钠法测定 MnO2含量与直接滴定法测定Mn2+的基础上,提出了一种新的分析电池级二氧化锰的方法.连续采用氧化还原滴定及络合滴定两步滴定,简便快捷,经实验验证,具有很高的准确度和精密度
Abstract:
A new analysis method was proposed on the basis of the previous method.It was confirmed experimentally that this analysis method is simple,rapid and has very high accuracy and repetition.
