Abstract

Language:

Electrocoagulation (EC) technique is applied for the treatment of wastewater containing heavy metals ions such as nickel (Ni), lead (Pb) and cadmium (Cd) by using sacrificial anodes that corrode to release active coagulant flocs usually aluminum or iron cations into the solution. During electrolytic reactions, hydrogen gas evolves at the cathode. All the experiments were carried out in batch mode. The tank was filled with synthetic wastewater containing heavy metals, and the efficiency of electrocoagulation in combination with aluminum and iron electrodes was investigated for the removal of such metals. Several parameters, such as contact time, pH, electro-coagulant concentration, and current density were optimized to achieve maximum removal efficiency (%). The concentrations of heavy metals were determined by using Atomic Absorption Spectroscopy (AAS). It is found that the electrocoagulation process has potential to be utilized for the cost-effective removal of heavy metals from wastewater, especially using iron electrodes in terms of high removal efficiencies and operating cost.
