Electrodeposition of Heavy Metals (Cu; Ni; Zn and Cd) from Industrial Effluents

Our technique consists on the recuperation of heavy metals such as Cu; Ni; Zn and Cd from an industrial wastewater by electrode position. The experiments were carried out in a cell of a capacity of 1 litre. The electrodes are made of stainless steel sheets for the cathode with a surface of 1dm2 and a grid anode of titanium coated with ruthenium oxide. The water flow (1) was constant and kept at a rate of 0, 35 l/min. The pH of the solution was at 1 for the removal of Cu; Ni; Zn and Cd. Different values of current densities are applied to remove elements. More than 98% of metal reduction was obtain and the solution obtained contains metals concentrations in agreement with Algerian legislations.
