This paper reports the removal of Cadmium ions from aqueous solutions using chitin/polyethylene glycol binary blend. Effect of various process parameters such as initial metal ion concentration, pH, adsorbent dose and contact time has been studied for the removal of Cadmium. Experimental data were analysed by Langmuir and Freundlich adsorption isotherms. The characteristic parameters and related correlation coefficients have been determined. The isotherm study revealed that the adsorption equilibrium is well-fitted to the Freundlich isotherm. Pseudo-first- and - second-order kinetic models were used for describing kinetic data. The results indicate that under the optimum conditions, the chitin/polyethylene glycol blend was found as an favorable adsorbent for cadmium.
