The paper presents the main features of Dubinin's theory for the volume-filling of micropores, its direct consequences in the field of immersion calorimelry and recent developments such as the possibility to describe type V isotherms (water on active carbons) with the Dubinin-Astakhov equation, and to deal with multiple adsorption under static and dynamic conditions. It also confirmed that in... More
Add to personal list- Résumé
- Ce travail présente la théorie de Dubinin, ses conséquences en calorimétrie d'immersion ainsi que des développements recents. En particulier, la description des isothennes de type V par I'équation de Dubinin-Astakhov (vapeur d'eau sur les charbons actifs) et la combinaison avec la theorie de Myers et Prausnitz qui conduit à une description de l’adsorption multiple en régimes statique et dynamique. La théorie de Dubinin inclut également l’adsorption de vapeurs par certains solides non poreux.
- Summary
- The paper presents the main features of Dubinin's theory for the volume-filling of micropores, its direct consequences in the field of immersion calorimelry and recent developments such as the possibility to describe type V isotherms (water on active carbons) with the Dubinin-Astakhov equation, and to deal with multiple adsorption under static and dynamic conditions. It also confirmed that in some cases Dubinin's theory applies to adsorption by non-porous surfaces.
