Characteristic Values

The adsorption of benzene vapor on natural and acid activated bentonites was treated by the theory of volume filling of micropores. The micropore volume and characteristic values of the free energy of adsorptionwere determined from the adsorption isotherms. The Dubinin?Radushkevish?Stoeckli and Dubinin?Astakhov equations were used for this purpose. The results showed that natural bentonite has a more homogeneous micropore structure than the acid activated ones. The characteristic values of the free energy of adsorption for the natural bentonite were higher than those of the acid activated bentonite. This is due to differences in its structure and the pore size.

Particle Adsorption

Small particles can adsorb strongly at fluid interfaces and form monolayers which can be studied using a Langmuir trough. For sufficiently large particles the monolayers can be viewed microscopically. The driving force for particle adsorption is the concomitant removal of fluid/fluid interface. For very small adsorbed particles, the free energy of forming the three-phase contact line around particles (hence the line tension) may also contribute significantly to the free energy of adsorption. Adsorption can be enhanced by having areas of particle surface with different wettability (Janus particles). Monolayers have structures dependent on lateral interactions between particles; for particles at the oil/water interface, electrical repulsion through oil is often the dominant interaction, which can give rise to highly ordered monolayers. Adsorbed particles can either inhibit or facilitate the formation of stable thin liquid films, depending on particle wettability.
