Comparism of Adsorption Behaviour of Caryota Rumphia na Flower and Goat Hooves to Lead and Manganese Ions in Aqueous Solution

Abstract

The adsorption of Pb 2+ and Mn 2+ 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 o f initial metal ion concentrations and contact time were evaluated. Pb 2+ and Mn 2+ ions attained equi- lib riu m within 60 and 120 minutes respectively for both cellulosic and keratinous material. The equilib riu m 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 Pb 2+ and Mn 2+ ions fro m aqueous solution.
