Abstract
The adsorption properties of a Silipore 200 surface and chemically modified sorption materials containing nickel, cobalt, and copper acetylacetonates are studied via gas chromatography. n-Alkanes (C6–C9) and adsorbates, the molecules of which have different electron-donating and electron-acceptor properties, are used as test compounds. From experimental data on the retention of adsorbates; their differential molar adsorption heats \(\bar q_{dif,1}\); changes in standard differential molar entropy \(\Delta \bar S_{1,C}^S\); and, for polar adsorbates, contributions \(\Delta \bar q_{dif,1(specific)}\) to the energy of dispersive and specific interactions, are calculated. The effect the metal ion in the structure of acetylacetonate has on the characteristics of thermodynamic retention is shown.
