Abstract

On the basis of an equation proposed previously, a method for calculating the isotherms of water-vapor sorption by swelling hydrophilic sorbents is outlined. The construction of the isotherms entails some information on the physicochemical characteristics of the system — for example, the binding energy of the sorbate molecule with the active center, the degree of hydration of the sorbent, the temperature, the sorptional centers and their mutual position, etc. As an example, the calculation of the isotherms of water-vapor sorption by cotton is considered.
