diffusionadsorption
Diffusionadsorption refers to a coupled transport process in which molecules diffuse through a medium and simultaneously adsorb onto solid surfaces within that medium. This combination is important in porous materials, membranes, and thin films where the movement of species is hindered or stored by interactions with surfaces. Diffusionadsorption can slow diffusion, create concentration gradients between phases, and control overall transport rates in systems such as soils, clays, catalysts, and filtration media.
In modeling diffusionadsorption, a mass balance is typically written to account for diffusive transport and the
Applications of diffusionadsorption include predicting contaminant transport in groundwater and soils, designing sorption-based filtration and remediation
