Abstract

Terminalia Catappa L. fruit shell, an agricultural waste as a low cost adsorbent has been studied for removing of Pb(II), Cd(II) and Cu(II) ions. The optimum adsorpt ion condition of Pb(II) and Cu (II) ion onto Termin alia Catappa L. fruit shell was occurred at pH 5, 100 rpm in 0,1 g biomass with each contact time was 45 and 75 min utes, metal ion concentration was 150 mg/L and 100 mg/L with a dsorption capacity was 12.6700 mg/g and 5.4400 mg/g . The optimum adsorption conditions of Cd (II) ion was oc curred at pH 6, 100 rpm in 0,1 g biomass with cont act time was 60 minutes, metal ion concentration was 150 mg /L and adsorption capacity was 16.4625 mg/g. The me tal ion concentration was analyzed by Atomic Absorption Sp ectrophotometry (AAS) method. FTIR spectra analysis might revealed that carboxyl, hydroxyl and carbonyl group s were dominant in the process of metal ions uptake . SEM analysis the morfology of biosorbent before and aft er treatment. Aplication to liquid waste obtained t hat adsorption efficient of Terminalia catappa L. fruit shell to a dsorp Pb(II), Cd(II) and Cu(II) ion was 55.879 %, 8 6.375% dan 41.565% respectively.
