dc.description.abstractThis paper describes modification of a natural adsorbent with Fenton reagent and determines the removal of Cd(II) ions from aqueous solution. Changes of the surface properties of adsorbent materials were determined by the FT-IR analysis after the modification of pine bark. The effect of Fe2+/H2O2 ratio, ORP, pH, and contact time were determined. Different adsorption isotherms were also obtained using concentrations of Cd(II) ions ranging from 0.1 to 100 mg L-1. The adsorption process follows pseudo-first-order reaction kinetics and follows the Langmuir adsorption isotherm. The paper discusses thermodynamic parameters, including changes in Gibbs free energy, entropy, and enthalpy, for the adsorption of Cd(II) on modified bark, and revealed that the adsorption process was spontaneous and exothermic under natural conditions. The maximum removal efficiency obtained was 97% at pH 7 and with a 90-min contact time (for 3 5 mg L-1 initial concentration and a 2.5 g L-1 solid-to-liquid ratio). (C) 2007 Elsevier Ltd.
