The adsorption capacity of the chemically modified bio-sorbent of charred banana peel (CBP) with 1:2 (w/v) concentrated sulfuric acid was studied to remove the Fe (II) ions from industrial wastewater and the applicability of Langmuir and Freundlich isotherms was tested. The adsorption kinetics of the Fe (II) ions onto the CBP was studied using pseudo-first order, pseudo-second order and second order kinetics equations. Result shows that the optimum pH for Fe (II) adsorption onto the CBP was found to be 3 and the adsorption efficiency was found to be about 98 % and the maximum adsorption capacity was found to be 33.79 mg/g. These results showed that the CBP may be an attractive alternative for treatment of the industrial wastewater contaminated with Fe (II) ions.
