A New Film Diffusion Controlling Kinetic Model for Adsorption at the Solid/Solution Interface

A New Film Diffusion Controlling Kinetic Model for Adsorption at the Solid/Solution Interface

A convenient adsorption kinetic equation has been offered for the modeling of adsorption kinetics in batch systems when diffusion taking parts to the rate-controlling step of adsorption. This model is suggested based on the Smoluchowski-Waite equation for diffusion-controlled second-order reactions....
