INTERACTION BETWEEN ADSORPTION AND CONDENSATION PROCESSES IN A PORE AND ITS EFFECT ON HYSTERESIS

Capillary condensation is treated on the basis of its relation to the properties of the interface between the pore walls and the condensed sorbate. Effects resulting from the interaction between adsorption and condensation processes at the pore are examined. The approach allows a more accurate assessment of the sorption isotherm, and leads to a simple explanation of hysteresis.
