Abstract

Structural and energetic characteristics of water adsorbed onto silica Gasil 200DF at its amounts much smaller than the pore volume were investigated using low-temperature 1H NMR spectroscopy and cryoporometry. The effects of such co-adsorbates as weakly polar (chloroform, methane) and polar (acetonitrile and DMSO) on bound water were analyzed. These co-adsorbates can displace water into pores of both larger and smaller sizes, and these effects are concentation-dependent.
