- Аннотация: Abstract Adsorption isotherms were measured by the gas chromatography method over the temperature range 50–80°C, and isosteric heats of adsorption of water isotopomers were calculated in the region of low coverages on two active carbons (Norit and FAS) with similar volumes of micropores (0.38 and 0.37 cm3/g) but different chemical properties of the surface (the surface of active carbon (AC) Norit is hydrophilic and that of AC FAS, hydrophobic). The isotherms on AC Norit were convex and those on AC FAS concave toward the axis of adsorption. At all equilibrium pressures, the adsorption of H2O and D2O on AC Norit was much higher than on AC FAS. The isotherms of adsorption of H2O and D2O were quite similar on both adsorbents, but the isotherms and heats of adsorption of D2O were slightly higher than those of H2O because of small differences in adsorbate-adsorbent and adsorbate-adsorbate interactions and the structure of adsorbate molecules.
