摘要/Abstract

摘要： Four models for the rate of adsorption in an adsorbent (slab-like, cylindrical or spherical) are presented.The parabolic
profile (PP) model is obtained by assuming a parabolic intraparticle concentration profile. The shell-core (SC) model is
based on a shell-core type profile.The modified shell-core (MSC) model is an extension of the SC model. And the general
driving force (GDF) model is a weighted average of the PP and MSC models.Sample calculations show that the GDF model provides
the best approximation.
