Summary

New working material "CaCl2 confined to mesoporous host matrix MCM-41" is synthesized and studied. For this mesoporous system, the isobars, isosters and isotherms of the water sorption are obtained at temperatures of 293-423 K and the vapour partial pressures 8.7-50.3 mbar. The water sorption is found to be a combination of a liquid absorption and a heterogeneous adsorption. The obtained results evidence the considerable change of the salt properties due to its confinement to the MCM-41 nanopores. A brief comparison of this sorbent with a pure silica gel is made.
