BATCH ADSORPTION OF p-NITROPHENOL AND p-CHLOROPHENOL ON ANION EXCHANGE RESIN

Abstract

A model was proposed by simplifying the surface diffusion model. In addition, three models-the simplified model, the quadratic driving force model and the surface diffusion model-were used to analyse experimental data of the adsorption of p-nitrophenol and p-chlorophenol on anion exchange resin (lonac AFP-329) in a batch adsorber. The simplified model gives a better approximation to the surface diffusion model than does the quadratic driving force model. Moreover, from the experimental data the result also shows that the surface diffusion coefficient varies linearly with q^1/n_∝.
