N2 - The immobilized biomass of green algae Spirogyra subsalsa was used as biosorbent for removal of lead (II) from aqueous solution. The effects of operating parameters, such a flow rate, influent pH and influent metals concentration were investigated. Significantly, the immobilized biomass showed IR spectrum not difference with free algae biomass. The biosorption process were a repaid process, where in more than 50% of the final uptake value occur at rate flow 1.5 mL/minute. The biosorption capacities of biomass for cations increase rapidly with pH between 2,0-3,0 then the maximum sorption was seen at pH 4,0. The biosorptive capacity increased with initial concentration in the range 50-200 mg/L. A comparison of the biosorption of Pb2+ cation by immobilized and free algae biomass showed an increase in uptake of over 4,25%. The immobilized biomass could be regenerated using nitrate acid, HNO3, and significantly proportional with using nitrate acid concentration, with up to 89% Pb2+recovery by 0,5 M HNO3. This study suggests that such an immobilized biosorbent system has the potential to be used in the industrial removal and recovery of Pb2+ cation from aqueous solution.
