Removal of Cobalt from Drinking Water by Alternating Current Electrocoagulation Technique

Saber E. Mansour, Ibrahim H. Hasieb and Hussein A. Khalaf

Abstract:
This research presents a preliminary study for the removal of cobalt from drinking water using Alternating Current Electrocoagulation (ACE) technology. The experiments were carried out using batch apparatus. Batch experiments with two monopolar aluminum plate anodes and cathodes were employed as electrodes. The effect of operational parameters such as initial pH, current density, reaction time, initial concentrations, solution conductivity and inter-electrode distance were studied in an attempt to reach higher Co (II) ion removal efficiency. Important operating parameters were optimized to attain higher (98.60%) Co(II) removal efficiency as follows: inter-electrode distance: 0.005 m, current density: 0.04 A m-2, operating time: 35 min, pH: 7.5, conductivity: 13 S m-1, frequency: 50 Hz and voltage: 50 V. The adsorption process followed first- order kinetics and the temperature studies showed that the adsorption was exothermic and spontaneous in nature.
