摘要:	A pseudo-second order and a pseudo-first order mechanism for the sorption of Omega Chrome Red ME as well as o-cresol and p-nitrophenol onto fly ash have been compared. Intraparticle diffusion processes and chemical sorption processes for the sorption also have been studied. The batch data for the sorption of Omega Chrome Red ME, o-cresol and p-nitrophenol onto fly ash have been analysed to predict the rate constant of sorption based on the assumption of a pseudo-second order mechanism. The equilibrium capacity and initial sorption rate have also been determined to study the effect of initial solute concentration and temperature on the sorption process. An activation energy of sorption has also been evaluated using the pseudo-second order rate constants.
