Conclusions
-
1.
Some features of the properties and adsorption of water vapor by carbon sorbents induced by a change in the properties of the adsorbate due to an increase in the number of hydrogen bonds on filling of the adsoprtion area were examined.
-
2.
The initial segment of the adsorption isotherms was calculated with the equation from the theory of volume filling of micropores and it was shown that the properties and adsorbability of water vapor on carbon sorbents at low relative pressures are similar to low-boiling gases with molecules of similar size.
-
3.
As the adsorption area fills, the increase in the number of hydrogen bonds formed correspondingly decreases the hypothetical saturated vapor pressure, which is responsible for the S-shape of the isotherm of adsorption of water vapor by carbon sorbents.
