| Abstract: | The electrodialysis technique was used to treat the wastewater of electroless nickel plating,and the effect of three technical conditions including current density,aging liquid pH and flow rate on the removal(loss) rate of various ions was mainly studied.The optimal process conditions are obtained as follows:current density 65 mA/cm2,pH = 4.5 and flow rate 1 L/45 s,and the performance of the regenerated bath were tested.Results indicated that the plating speed,phosphorus content and hardness had been reach ... |
