摘要
用稀硫酸溶解试样,用草酸钠还原法,以定量的草酸钠还原锰矿石中的MnO2,再用高锰酸钾标准溶液滴定剩余的草酸钠,求出MnO2的含量。实验结果表明,分析误差完全在国标分析误差允许范围内。
Manganese ore sample was solved with dilute sulfuric acid. Using sodium oxalate reduction method,that is,the MnO2 in sulfuric acid medium was reduced by quantitative sodium oxalate,and then the remaining sodium oxalate was titrated by potassium permanganate standard solution for finding the content of MnO2. The experimental results showed that the analytical error was entirely in the national standard analytical error allowed range.
