Abstract: The aim of this study was to establish an electrolytic method for removal of metals from wastewater, using a three-dimensional reticulated vitreous carbon cathode, assembled in a flow-through cell, During development of the experiments, particular attention was paid to the electrolyte flow rate and to cathode porosity. The electrolytic cell employed potential values in such a way that the metal reduction reactions occurred under mass transport control, These potentials were determined by hydrodynamic voltammetry on a vitreous rotating disc electrode, The cell proved efficient in removing copper, zinc and lead, and was; able to reduce the levels of these metals from 50 mg/L to 0.1 mg/L, The optimum configuration was cathode porosity of 80 ppi and solution flow in excess of 100 L/hr.
