The removal of ionic copper from electroplating wastewater was investigated using a five-compartment electrodialysis cell. The experiments were carried out using two different types of ion-exchange membranes (Purolite A500, Purolite PPC100). The effects of initial copper ions concentration, solutions conductivity, solutions pH on the duration of electrodialysis, massic flow (the amount of copper deposited on the cathode lead), and extraction percentage of copper ions were determinated. The electrodialysis unit operates under the constant applied voltage (7.5 V), with the electrolyte recirculation. When initial copper ions concentration is high (4 g/L), the extraction percentage of copper ions increased (>85%). Chemical stability of ion exchange membranes was investigated by Fourier transformed infrared spectroscopy. The results show that the membranes were not damaged during the electrodialysis, after three hours.
