| Abstract: |
| The thermodynamic equilibrium of removing copper from nickel anode electrolyte by sulfide method was calculated according to the known thermodynamic data and the logcMe-logcS and c-pH diagrams for nickel anode electrolyte system were drawn at 298.15 K.The results show that total copper,part of lead and zinc can be removed from nickel anode electrolyte by sulfide method.In addition,increasing copper concentration,reducing nickel concentration and controlling adequacy pH are beneficial to the removing process... |
