| titleOfInvention | Method for preparing high-purity hydrated manganese sulfate employing dual washing method |
| abstract | The invention discloses a method for preparing high-purity hydrated manganese sulfate employing a dual washing method, and belongs to the technical field of electrochemistry. The method comprises the following steps: 1) reacting a manganese sulfate solution with aqueous alkali at the molar ratio of Mn＜2+＞ to OH＜-＞ being 1 to 2, so as to prepare manganese hydroxide sediments; 2) washing the manganese hydroxide sediments with water, reacting manganese hydroxide with sulfuric acid at the equal molar ratio, and generating manganese sulfate; and 3) reacting manganese sulfate with ammonium bicarbonate to generate manganese carbonate sediments, washing the manganese carbonate sediments with water, reacting the washed manganese carbonate sediments with sulfuric acid, filtering, evaporating, concentrating and drying, so as to prepare the high-purity hydrated manganese sulfate. Separation of different ions and purification of manganese sulfate are achieved by using different solubility of different metal ion salts and a plurality of times of precipitation and washing treatment. |
