An investigation on the adsorption capacity of carbon particle for the removal of Fe3+ ion from water

Abstract

Carbon particle was prepared from Sugarcane Bagasse by using carbonization method. The surface morphology of carbon particle was characterized by SEM and EDX. The results from EDX showed that this adsorbent is not a pure carbon. The iodine number suggests that this is a good activated charcoal. The capacity of SB charcoal to remove Fe3+ ion from water by adsorption technique was studied by Langmuir and Freundlich adsorption isotherm. Adsorption isotherm testing suggest the formation of multilayer and having heterogeneous surface energy. The Fe3+ ion adsorption capacity of SB charcoal was moderately satisfactory. The degree of elimination of Fe3+ ion was found to be dependent on pH, adsorbent dosage, initial metal ion concentration and milling time of adsorbent. Result shows that the optimum pH is 8 for about 74.75% Fe3+ ion adsorption onto the SB charcoal for 130 minutes contact time.
