Biosorption of heavy metals can be an effective process for the removal and recovery of heavy metal ions from aqueous solutions. In this paper, the comparative adsorption properties of non-treated and basically pre-treated pods biomass of local gram cultivar (LGC) biomass with NaOH, Ca(OH)(2) and Al(OH)(3) for Ph (II) uptake was investigated. Equilibrium isotherms and kinetics results were obtained from batch adsorption experiments. The biosorption capacities were solution pH dependent and the maximum capacity obtained was 34.28 mg/ g at a solution pH of about 5. The biosorption kinetics was found to be fast, with most of adsorption within 240 min and equilibrium reached at 480 min. This study demonstrated that the NaOH pre-treated pods biomass of LGC could be used as an effective biosorbent for the treatment of Pb (II) containing wastewater streams.
