The kinetic aspects of adsorption of some priority organic pollutants, viz., phenol (hydroxybenzene), o-hydroxyphenol (1,2-dihydroxybenzene), m-hydroxyphenol (1,3-dihydroxybenzene), and 4-nitrophenol (1-hydroxy-4-nitrobenzene), on fly ash have been studied. The process is found to be of complex nature consisting of both surface adsorption and pore diffusion, the extent being estimated from the diffusion coefficient value. Activation parameter data for the ultimate adsorption as well as the pore diffusion are also evaluated. The data indicate that in the studied solute concentration range, external transport mainly governs the rate-limiting process. (C) 2003 Elsevier Inc. All rights reserved.
