本文介绍不经氢氧化钡沉淀分离,在强碱性溶液中直接用亚硫酸钠把高锰酸钾还原为锰酸盐,然后用草酸滴定还原前后的两份试液,通过计算便可快速求出高锰酸钾和锰酸盐含量,精确度可满足生产要求。
This article describes the separation without barium hydroxide precipitation, potassium permanganate is directly reduced to manganate with sodium sulfite in a strong alkaline solution, and then titrated with oxalic acid two test solution before and after reduction, can be calculated quickly you can find high Potassium manganate and manganate content, accuracy to meet production requirements.
