| Abstract: | The influence of temperature, current density, pH, cell voltage and manganese ion concentration and nickel ion concentration on Ni MnO 2 simultaneous electrolysis process and the current efficiency was studied Based on the orthogonal experiment results, the best electrolysis technical condition showed as follow: Ni 2+ ] 90g/L;Mn 2+ ] 30g/L;pH 3 5;90℃;current density 165A/m 2;=15g/L,cell voltage 2 86V, the cathode efficiency can reach 98 88%, and the anode efficiency nears 100%, the cathode nickel can reach Grade 1 level, and the pureness of the anode manganese dioxide is suit for the cell industry |
