Ni2+ in the solutions were effectively removed by the electrodialyzer. The initial concentration of dilute solution, the flow velocity and the current strongly affected the performance of the electrodialysis system.The experimental results: when the material concentration of dilute solution (Ni2+ concentration of 0.50g/L), the flow velocity of complexing room 80L/h and the current (1.5A)are considered the best condition.The mixed solution of Cu2+ and Ni2+ were almost removed.
