Removal of Heavy Metals (Cd, Cu, Ni) by Electrocoagulation

Umran Tezcan Un and Sadettin Eren Ocal

Abstract—In this study, removal of cadmium (Cd), copper (Cu) and nickel (Ni) from a simulated wastewater by electrocoagulation (EC) method using batch cylindrical iron reactor was investigated. The influences of various operational parameters such as initial pH (3, 5, 7), current density (30, 40, 50 mA/cm2) and initial heavy metal concentration (10, 20, 30 ppm) on removal efficiency were investigated. It was seen from the results that removal efficiencies were significantly affected by the applied current density and pH. The experimental results indicated that after90 minutes electrocoagulation the highest Cd, Ni, Cu removal of 99.78%, 99.98%, 98.90% were achieved at the current density of 30 mA/cm2 and pH of 7 using supporting electrolyte (0,05 M Na2SO4) respectively. The experimental results revealed that the removal of heavy metal ions by our design electrochemical cell can be successfully achieved.
