Further verification of adsorption dynamic intraparticle model (ADIM) for fluid–solid adsorption kinetics in batch reactors

Recently, a diffusive intraparticle dynamic model has been published by the authors and applied for describing few systems in order to check its validity. The aim of the present paper is to improve its validity in describing different kind of systems. At this purpose, adsorption data have been taken from literature, in which different adsorbate/adsorbent systems have been considered. In every case, the surface diffusivity of the pollutant (D-S) has been fitted on the experimental data. The obtained parameters fall within reasonable ranges and a good fitting has been obtained for each case, demonstrating the generality of the adopted model. (C) 2015 Elsevier B.V. All rights reserved.
