【摘要】 本篇报导用二氯化锰电解液电解金属锰时,电流密度、温度、添加剂亚硒酸浓度、氯化铵浓度、电流浓度等因素对电流效率的影响;并研究了在阴极电沉积锰的同时,在阳极联产电解二氧化锰的电解条件。从10小时连续电解得出的结果:阴极电流效率可达74.5%,阳极电流效率可达94.5%;每消耗4千瓦小时左右的电能,可以同时得到1公斤锰和2公斤二氧化锰。

【Abstract】 Results of beaker scale and large laboratory scale experiments on the deposition of manganese from chloride electrolyes are reported for conditions where fibrous electrolytic manganese dioxide is the anodic product. Anolyte and catholyte compartments were provided by dividing the cell with a porous porcelain plate. Graphite blocks were used as anode and stripts of titanium as cathode.The influence of various factors, such as current density temperature, concentrations of ammonium chloride and addittives on current efficiency of electrodeposition of metallic Mn have been studied. To produced one kilo-gram of metallic Mn as well as two kilo-gram FEMD an electric energy of only four to five kilowatt hour would be required. The current efficiency of electrolyzing metallic Mn arrives or surpasses the advanced level reported recently.
