Abstract
1. The volumetric-gravimetric method was used to study the adsorption of a mixture of water and ethyl chloride vapors on active charcoal with growth of intermediate porosity at a temperature of 75°. 2. The set of isotherms for the adsorption of water at constant values for the adsorption of ethyl chloride can be described in a certain region by the equation proposed by Dubinin and Serpinskii. The set of isotherms for the adsorption of ethyl chloride at constant values for the adsorption of water can be described in the entire region studied by the equation derived by Dubinin, Saverina and Radushkevich for charcoals of the first structural type. 3. The effective density of the water, adsorbed in the micropores of charcoal, is substantially greater than the normal density of water at the same temperature. Transition to sorption in the region of capillary condensation is characterized by a reduction in the water density. 4. Combining the two indicated equations makes it possible to satisfactorily describe the adsorption of a mixture of water and ethyl chloride vapors on active charcoal, employing the parameters of the individual adsorption isotherms of the two compounds and one empirical parameter when water adsorption a1≤2 mmole/g.
