Abstract

The results in this study shows that Electro Coagulation (EC) process using Aluminium plates as sacrificial anodes strongly depends on pH, current density, operating time, inter-electrode distance, initial concentration and adsorbent Granular Activated Carbon (GAC) dosage. At nearly neutral pH, effective removal was achieved and both electrochemical reduction reaction at the cathode surface and adsorption on Al(OH)3 floc mechanisms were responsible for phenol exhaustion. Increasing current density in a range 7.8 to 25 mA/cm2 enhances the removal efficiency from 57.0% to 82.4%. By addition of adsorbent GAC the removal efficiency of phenol significantly increased at lower current densities and operating time, with 13.6% more than the conventional EC process under the same operating conditions
