中文摘要：

对阴离子交换膜电解槽在氯盐电解质中电沉积锰进行研究，并采用循环伏安法对其进行电化学分析。研究结果表明：电解最佳条件是锰离子浓度为0.9 mol/L，氯化铵浓度为2.4 mol/L，电解温度为40 ℃，电流密度为450 A/m2，pH为7.3，SeO2浓度为0.36 mmol/L，在此条件下，金属锰的电沉积效率为90.8%，电耗为4 816 kW·h/t；其晶型为γ型；利用离子膜电解槽电沉积金属锰能有效地防止阴极表面Mn2＋的浓差极化，提高电流效率，该过程所发生的还原反应为扩散过程控制。

英文摘要：

The electrodeposition of metallic manganese using electrolytic membrane reactor from chloride-based electrolytic solution was investigated, and the electrochemical scanning of the processes was tested by cyclic voltammetry. The results show that the current efficiency can be up to 90.8% and the power consumption can be reduced to 4 816 kW·h/t under the condition of manganese ion concentration of 0.9 mol/L, ammonium sulfate concentration of 2.4 mol/L, temperature of 40 ℃, current density of 450 A/m2, pH of 7.3 and SeO2 concentration of 0.36 mmol/L, and the manganese phase is γ-manganese. The process can prevent Mn2＋ concentration polarization on the cathode surface and increase the current efficiency in the anion-exchange membrane. The metallic manganese reduction is a diffusion-controlled process.
