Abstract	In the present work the ability to remove Pb (II) from aqueous solutions has been studied using by Banana peel (BP) as adsorbent. Effects of pH, concentration of the Pb (II), contact time and adsorbent dosage have been studied. The optimum conditions of biosorption were found to be: pH 5, initial Pb (II) concentration: 20 mg.L –1 , contact time of 60 min and a BP dose of 0.48 g L -1 , respectively. In optimum condition, removal efficiency was 88.45%.Equilibrium isotherms for the adsorption of the Pb (II) were measured experimentally. Results were analyzed by the Langmuir and Freundlich equations at different temperatures and determined the characteristic parameters for each adsorption isotherm. The results showed that the equilibrium adsorption of Pb (II) onto banana peel was best described by Langmuir isotherm model and the Langmuir model was found to fit the data significantly better than Freundlich model. The maximum biosorption capacity of BP for Pb(II) was found to be 400.0 mg g -1 at 45
