A BET approach to multilayer adsorption in swelling products

Mostrar todas las versiones(2)

An equation for multimolecular sorption is presented. It is based on the BET model with the assumption that the adsorbing surface can be divided in two regions: A region that supports only a limited number of adsorbed layers due to geometric restrictions, and another region that can adsorb an unlimi...
