| titleOfInvention | A kind of method of manganese sulfate electrolyte purification dechlorination |
| abstract | A kind of method of manganese sulfate electrolyte purification dechlorination, bismuth oxide activates in concentrated sulfuric acid first makes it be converted into sulfuric acid oxygen bismuth, secondly activation slag is added to manganese sulfate solution and adjusts solution ph to initial value with manganese salt, precipitate the chloride ion in solution in the form of chlorine oxygen bismuth, purification slag concentrated sulfuric acid digestion is eventually adding bismuth ion remaining in liquid after manganese powder displacement purge to remove chlorine and realize that precipitating reagent regenerates again.Essence of the invention makes bismuth oxide be converted into active preferable sulfuric acid oxygen bismuth first, and then the feature small using chlorine oxygen bismuth solubility product, with the chlorine in sulfuric acid oxygen bismuth removing manganese sulfate electrolyte, the property for being easy to volatilize using hydrogen chloride again, chlorine oxygen bismuth is set to be regenerated as sulfuric acid oxygen bismuth, property finally lower than bismuth using the electrode potential of manganese makes bismuth displacement recycling remaining in liquid after purifying.The present invention has the advantages that short technical process, good product quality and at low cost. |
