Abstract Pyrorized tire carbon (PTC) was prepared by pyrolyzing waste automotive tire (WAT) at temperature of around 500 oC for 4 h in an oxygen-free atmosphere and evaluated as adsorbent for the removal of Cd(II) ions from aqueous solution. It was observed that PTC has greater adsorption efficiency for Cd(II) ions as compared to commercial activated carbon (CAC) due to the presence of its higher mesopore volume. The adsorption characteristics of Cd(II) ions were investigated by means of equilibrium and kinetic studies. The Freundlich isotherm and the pseudo-second-order kinetic model fitted well to the adsorption data of Cd(II) ions. Maximum adsorption capacities of Cd(II) ions on CAC and PTC were found to be 0.96 and 6.81 mg g-1, respectively. The results of the present study suggest that PTC could be used beneficially for the removal of Cd(II) ions from aqueous solution.
