The adsorption of Pb2+ and Mn2+ ions by cellulosic (Caryota rumphiana flower) and keratinous (Goat hooves) materials was investigated in order to compare their adsorptive capability. The experiments were carried out by batch method at 30℃ and the effect of initial metal ion concentrations and contact time were evaluated. Pb2+ and Mn2+ ions attained equilibrium within 60 and 120 minutes respectively for both cellulosic and keratinous material. The equilibrium data fitted the Freundlich adsorption isotherm. This study demonstrated that Caryota rumphiana flower and Goat hooves could be used as an alternative adsorbent to remove Pb2+ and Mn2+ ions from aqueous solution.
