In this study, the adsorptive capacity of the synthetic Indion 225Na cation exchange resin was evaluated for the removal of different ions species from Oil Refining Company wastewater. Batch studies were performed to evaluate the effects of various experimental parameters by such as pH, contact time, temperature, resin and initial concentrations on the removal ion species. The Indion resin was characterized using FT-IR spectroscopy and scanning electron microscopy were used to analyse the resin. The adsorption kinetics were fitted by the pseudo-first-order, pseudo-second-order kinetic equations and intra-particle diffusion model. The thermodynamic parameters, sticking probability and activation energy of the removal processes were also evaluated. Based on these results, the synthetic Indion 225Na resin could be applied for treatment of industrial effluents which are rich in inorganic pollutants.
