A mesoporous activated carbon derived from waste tyres was used to remove a toxic basic dye (malachite green oxalate, or MG) from aqueous solutions. The carbon contains a large volume fraction of mesopores and presents an excellent adsorption capacity of ~424 mg/g towards MG, which is much higher than a commercial carbon with similar surface area. The adsorption equilibrium and kinetics were found to follow Langmuir equation and second‐order kinetics, respectively. The structure of the carbon was characterised and based on which the dye adsorption mechanism was discussed. © 2012 Curtin University of Technology and John Wiley & Sons, Ltd.
