Influence of pore structure and particle size on rate determining step of lead (II) ions and nitrobenzene adsorption onto activated carbons (ACs) having no surface oxygen had been studied. The adsorption kinetics were examined using the Langumuir type rate equation. Nitrobenzene adsorption rate was found to be always controlled by collision between adsorbate and adsorption sites. Though the rate determining step of lead adsorption might include exterior and inter-particle diffusion, it could be shifted from exterior and inter-particle diffusion to collision between adsorbate and adsorption sites with either increasing mesopore content or reducing particle size by pulverization of ACs.
