The current study emphasizes on the ability of Banana peel to adsorb heavy metals from aqueous solutions. In batch mode studies the adsorption was dependent on initial metals ion concentration and agitation time. Although the adsorptive capacity of Banana peel is not high for heavy metals. Low cost of the material together with its adsorptive ability could offer a promising procedure for depollution of industrial wastewaters. The negative values of ΔG° suggested that the adsorption was spontaneous in nature. The positive value of ΔH and ΔS indicated endothermic adsorption process and increased randomness at surface–solution interface, respectively.
