Kurzfassung:
Here we present physical and chemical properties of CaCl 2 /H 2 O and LiBr/H 2 O systems confined to nanopores of silica gels. Sorption isobars, isosters and isotherms were measured at temperature 293 – 423K and vapor partial pressure 8–133 mbar. Specific heat of the systems was found as a function of temperature (300 – 400K) and sorbed water content (0 – 53 wt.%). Solidification/melting diagrams were measured over 170 – 320K temperature range at salt concentrations 0–50 wt.%. The results obtained evidenced a significant change in the thermodynamic properties of CaCl 2 /H 2 O and LiBr/H 2 O systems due to confinement to the silica gel micropores.
