Conclusions

  1. 1.

    Gas chromatography was used to determine the thermodynamic characteristics of the adsorption of normal alkanes, normal alkenes, alkylaromatic, haloaromatic, and polyaromatic hydrocarbons on BaSO4, which is an ionic adsorbent, with a modified surface.

     
  2. 2.

    The retention of the molecules (except for normal alkanes) is significantly dependent on the specific interaction of the adsorbed molecules with the BaSO4 surface.

     
  3. 3.

    The contributions of the specific interaction energy to the heat of adsorption were evaluated.
