| Abstract: | The process of reclaiming Ni (II) in wastewater to produce nickel sulphate was studied by electrochemistry method with activated carbon cathode. The effect of current consistency, initial concentration of Ni (II) in aqueous solution, pH value of aqueous solution and reaction temperature on reclaiming efficiency was discussed. The reclaiming efficiency of Ni (II) was up to 99.2% in the condition of current consistency of 0.05A/cm2, concentration of Ni (II) in wastewater 250mg/L, pH of aqueous solution 6.0, reaction temperature 30℃ and reaction time 150min. |
