The effectiveness of low-cost biosorbent: immobilized Sugarcane bagasse (Saccharum officinarum L.) onto alginate Polvinyl glutaraldehyde, was studied for Lead (II) biosorption from aqueous solutions in a batch system. The FTIR study of acid treated biosorbent showed that the possibility of availability of function groups such as hydroxyl, carbonyl, carboxylic etc. The SEM represents a porous structure with large surface area.XRD used for phase identification of a crystalline material The effects of operational factors including solution pH, biosorbent dose, initial chromium (VI) concentration, contact time and temperature were studied. The equilibrium isotherm data were comparing by using the Langmuir, Freundlich, DKR and Temkin adsorption isotherm models in which Langmuir isotherm was found to be fitted best. The Kinetics of sorption of Lead(II) were described by a pseudo-First-order kinetic, pseudo kinetic, Elovich and Weber and Morris intra diffusion model in which pseudo second order model was found to be fitted best. Thermodynamic studies were also carried out. The results showed that immobilized sugarcane baggase (Saccharum officinarum L.) alginate Polvinyl glutaraldehyde beads was a low-cost capable sorbent to seize Lead(II) from wastewater.
