Tannic acid was reacted by different amino organic compounds .also react with chitosan to obtain three modified chitosan biopolymer. Their chemical structures were characterized by FTIR and elemental analysis. The prepared biopolymers were used to adsorb Al (III) and Pb (II) metal ions from industrial wastewater.The factors affecting the adsorption process were biosorbent amount , initial concentration of metal ion and pH of the medium. The adsorption efficiency increased considerably with the increase of the biosorbent amount and pH of the medium. he adsorption process of biosorbent on different metal ions was fitted by Freundlich adsorption model.The adsorption kinetics was followed Pseudo-second-order kinetic model. The adsorption process occurred according to diffusion mechanism which was confirmed by the interparticle diffusion model. The modified biopolymers were efficient biosorbents for removal of Pb(II) and Al(III) metal ions from the medium
