Abstract: The homogeneous surface diffusion model (HSDM) has been used extensively to model the dynamics of adsorption of organic compounds onto porous media in natural and engineered systems. A modified finite‐difference solution ...

Abstract: The triple layer surface complexation model (TLM) is used to describe equilibria for lead, cadmium, and zinc adsorption on a recycled iron-bearing material that is treated as a hydrous oxide in aqueous solution. Using model ...

Abstract: A granular iron-bearing material recovered from surface finishing operations in cast-iron manufacturing is demonstrated to be an effective sorbent for removal of lead from wastewaters in laboratory-scale tests. Fixed-bed ...

Abstract: Iron oxide impregnated onto an activated carbon

Abstract: A steady-state mathematical model is presented to describe the kinetics of volatile organic compound (VOC) removal in biofilters that consist of a mixed compost and granular activated carbon (GAC) medium. The model describes ...
