Approximate semianalytical solution for nonlinear surface diffusion in a batch reactor

Development and evaluation of Mn oxide-coated composite adsorbent for the removal and recovery of heavy metals from coal processing wastewater. Final report, December 1995

“…respectively. Both systems were modeled by a homogeneous Surface diffusion model (HSDM) which is one of the most widely used models for activated carbons Wang and Roy, 1993;Traegner and Suidan 1989;Thacker et al, 1981). adsorbent, and local equilibrium occurs at the external surfice of an adsorbent particle and can be described by a Freundlich isotherm Equations descniing this model are (Thacker et al, 1981): …”

“…Among these diffusion model, the homogeneous solid surface diffusion model (HSDM) is one of the most widely used models for activated carbons (Thacker et al, 1981;Traegner and Suidan 1989;Wang and Roy, 1993;Roy et al, 1993).…”
