- A study on the adsorption characteristic of iron onto Poly[eugenol-co-(divinyl benzene)] (EDVB) from aqueous solution has been conducted. EDVB was produced and characterized by using FTIR spectroscopy. The adsorption was studied by a batch method by considering the factors affecting the adsorption such as initial metal ion concentration, adsorption selectivity, and mechanism of adsorption using a sequential desorption method. The adsorption of iron onto EDVB followed a pseudo-2 order kinetics model with the rate constant of 0,144 L2 .mmol -1 .min -1 . The adsorption isotherm was studied with Tempkin, Langmuir and Freundlich models. The adsorption capacity (Qmax) obtained by Langmuir isotherms was 250 mg.L while the equilibrium value was 0,8 Lmg -1 . A competitive adsorption study showed that EDVB is adsorbed selectively towards iron rather than chromium, coppers and cadmium ions. The interaction type of iron onto EDVB was determined by a sequential desorption.
