摘要
为了制备间接电解氧化用的Ｍｎ３＋，对硫酸锰均相电解氧化反应进行了实验研究．考察了电解时间、电极材料、硫酸锰浓度、硫酸浓度、阴阳极面积比及电解温度对电流效率和电解效率的影响．通过实验得出：采用炭棒做阴极，铅皮做阳极，Ｍｎ２＋浓度为０３０７ｍｏｌ·Ｌ－１，硫酸浓度为８４２ｍｏｌ·Ｌ－１，阴阳极面积比为１∶７，电解温度为４０℃，电解２ｈ，电流效率和电解效率分别可达５６８５％和４８５３％．
The electrooxidation of manganious salts was investigated.The conditions of electroreaction were discussed.The experimental results show crayon as catelectrode,lead sheet as electrode,concentration of Mn 2+ and sulfuric acid is 0.307 mol\5L -1 and 8.42 mol\5L -1 ,area ratio of catelectrode to electrode is 1∶7,temperature of the reaction is 40 ℃,current efficiency is 56.85 %
