Abstract:
The influence of the inorganic salt-silica gel surface interaction on the chemical and phase compositions and sorption properties of composites of the salt in silica gel pores type is studied. Two possible interaction mechanisms are considered: (1) the ion-exchange adsorption of metal cations on the silica gel surface from a solution of a salt (CaCl2, CuSO4, MgSO4, Na2SO4, and LiBr) and (2) the solid-phase spreading of a salt (CaCl2) over the silica gel surface. The adsorption of metal cations on the silica gel surface in the impregnation step affords ≡Si-OM n+1 surface complexes in the composites. As a result, two salt phases are formed in silica gel pores at the composite drying stage, namely, an amorphous phase on the surface and a crystalline phase in the bulk. The sorption equilibrium between the CaCl2/SiO2 system and water vapor depends on the ratio of the crystalline phase to the amorphous phase in the composite.
