摘要
本文对Ｎｉ－ＭｎＯ＿２同时电解的电极过程进行了热力学分析通过试验证实了Ｎｉ－ＭｎＯ＿２同时电解是可行的．并考察了温度、电流密度，Ｎｉ￣（＋２）浓度．Ｍｎ￣（＋２）浓度，阴极液ｐＨ等条件对电积过程的影响，在综合的最佳条件下试验获得满意的结果阴极产品符合特号镍要求，阳极产品为γＭｎＯ＿２，本流程较之常规流程可节电６０％～７０％。
A thermodynamic theoreticel analysis is conducted on the process of Ni-MnO_2simutaneous elertrolysis.The feasibility to simultaneously electralyze Ni- MnO_2 is confirmed bythe performed test by meaus of whieh effects of some conditions,such as tempreture. currentdenisty,concentrations of Ni￣(+2) and Mn￣(+2) as well as pH of cathodic solution,on the electrowinninghave also been、examined.On the basis of the optimum conditions satisfaetory results from thetest can be obtained as that products from the cathod are nickel metal of the supergrade and thosefrom the anode are MnO_2 , along with a decrease in power consumption by 60%to 70%comparedwith the previous process.
