The surface properties of various oxides (ZrO(2) and Fe(3)O(4)) and sulfides (HgS and FeS) were investigated by the inverse gas chromatography method (IGC). The retentions of several organics were measured in the temperature range from 330 to 500 K. The dispersive component of the surface free energy (gamma(d)(s)) of studied adsorbent surfaces was estimated using retention times of different nonpolar organics in the infinite dilution region. The gamma(d)(s) values decrease with temperature increase. The obtained results proved that IGC is an efficient and successful technique for the characterization of surface properties of these kinds of materials.
