The apparent and actual densities were measured for a set of seven porous samples with an identical carbon skeleton but differing in the content of inorganic salts. The corresponding values of porosity and density both of the active carbon skeleton and the impregnant of the whetlerites were calculated. In addition, the extractability of inorganic components from the samples was studied. On this basis, the chemical composition of the impregnant and a mechanism of the impregnant decomposition (occurring during its heat treatment) was proposed.
