The resulting product was evaluated for the removal of Arsenic and Cadmium ions from aqueous solutions. The prepared activated carbon was characterized using SEM, FTIR and XRD. Operational parameters such as initial concentration, adsorbent dose, contact time, effects of pH and temperature were studied in a batch system. It was found that the percentage removal for arsenic and cadmium were around 98 and 97% respectively. Equilibrium of the adsorption Original Research Article
