Abstract: | Adsorption of water vapor by granular polymer based on dibenzo-18-crown-6 and containing potassium nitrate or potassium picrate
in the polymer phase was studied by the isopiestic method at 298 K. The adsorption of water vapor is described by isotherms
corresponding (according to BDDT classification) to polymolecular absorption with a high adsorptive potential. In terms of
the Aranovich model of polymolecular absorption, the monolayer capacity and differential heat of adsorption were calculated,
and the stoichiometry of hydration of the potassium nitrate and potassium picrate complexes with immobilized crown ether was
estimated.
