Abstract

Liquid-phase adsorption removal of Cu²⁺, Co²⁺, Ni²⁺, and Pb²⁺ in the concentration range of 5-25 mg/L using low-cost banana and orange peel wastes was examined at 30 °C. Under comparable conditions, the amount of adsorption decreased in the order Pb²⁺ > Ni²⁺ > Zn²⁺ > Cu²⁺ > Co²⁺ for both adsorbents. The adsorption isotherms could be better described by the Freundlich equation. The amount of adsorption increased with increasing pH and reached a plateau at pH > 7, which was confirmed by the variations of zeta potentials. The application potential of such cellulose-based wastes for metal removal (up to 7.97 mg Pb²⁺ per gram of banana peel at pH 5.5) at trace levels appeared to be promising.
