| Abstract: |
| Manganese was electrodeposited in MnSO4-(NH4)2SO4-H2O system applying 1-butyl-3-methylimidazole as additive. Effects of current density, 1-butyl-3-methylimidazole concentration, ammonium sulfate dosage, Mn2+ mass concentration and cell voltage on cathode manganese deposition and current efficiency were investigated. The morphology of deposited manganese was characterized by XRD and SEM. The results show that in MnSO4-(NH4)2SO4-H2O system, the current efficiency is 79.60%, which is higher than that of SO2 and SeO2, under the optimum conditions including temperature of 40℃, Mn2+ mass concentration of 35 g/L, ammonium sulfate mass concentration 90 g/L, pH value of 7.5, current density of 364.58 A/m2, and 1-butyl-3-methylimidazole dosage of 0.12 g/L. The electrodeposited manganese is α-Mn. |
