Various models, based on mass transfer and different isothermal adsorption equilibrium laws, are developed using COMSOL Multiphysics.

These isotherms are representative of the adsorption of various pollutant-adsorbent systems frequently found in decontamination processes.

Consequences on breakthrough curves are examined and possible applications to decontamination processes are discussed.
