Abstract:
The results of studies on the mechanism of the adsorption of water molecules by nonporous and microporous carbon adsorbents carried out using various physicochemical methods are surveyed. The influence of the chemical state of the surface and the porous structure of adsorbents on the heat of adsorption and the mechanism of filling of the carbon surface and micro- and mesopores of carbon adsorbents are analysed. The nature of primary adsorption sites and the influence of the adsorption of water molecules on the X-ray diffraction parameters (microcrystalline structure) of carbon adsorbents are studied. The methods of investigation of the porous structure and chemical state of the surface of carbon adsorbents based on the analysis of water vapour adsorption isotherms are considered. The bibliography includes 80 references.
