Removal of Copper Ions from Electroplating Wastewater by Ion-exchange Membranes

The electrodialysis technique for the treatment of a synthetic wastewater containing copper was studiedusing three-compartment electrodialysis cell using different type of ion-exchange membranes. In this paperconductivity, pH, gravimetric evaluation and percent extraction was determined for different values of theapplied voltage. The best results were observed for A500, respective PPC100.Keywords: copper ions, electrodialysis, ion-exchange membranes, wastewater
