Abstract

For qualitative and quantitative description of adsorption equilibrium and hysteresis in open slit-like micropores, theoretically rigorous equations are proposed based on the theory of volume filling of micropores which imply the physical and formal analogy between the volume filling of micropores and capillary condensation. The applicability of the proposed equations for description of the hysteresis in such systems is demonstrated for water adsorption/desorption isotherm on the fibrous carbon material AUVM-Dnepr which possesses micro- and mesoporous structure.
