【 摘 要 】

Pyrolyzed tire carbon (PTC) was prepared by pyrolyzing waste automotive tire (WAT) at around 500°C for 4 h in an oxygen‐free atmosphere and evaluated as an 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 higher mesopore volume. The adsorption characteristics of Cd(II) ions were investigated by means of equilibrium and kinetic studies. The adsorption data of Cd(II) ions were universally applicable to the Freundlich isotherm and the pseudo‐second‐order kinetic model. Maximum adsorption capacities of Cd(II) ions on CAC and PTC were found to be 0.96 and 6.81 mg/g, respectively. The present study’ results suggest that PTC could be used beneficially for the removal of Cd(II) ions from aqueous solution.
