Biosorption of Pb(II) and Cd(II) from Aqueous solution was studied using Arenga pinnata shell immobilized in Calcium Alginate in batch mode. Uptake of metal was very fast initially and equilibrium was attained within 15 min. Sorption data conformed well both Langmuir and freundlich isoterm model for Pb(II), while for Cd(II), the langmuir is better than the freundlich isoterm model. Highest Pb(II) uptake (78,957 %) and Cd(II) uptake (51,022 %) by selected biomass (1 %) immobilized in 1 % Calcium Alginate occured at pH 4, 100 rpm for Pb(II) and 150 rpm for Cd(II) when both initial concentration was 10 mg/L.
