| Abstract: | Adsorbents were obtained on the basis of Silochrome S80 modified with complex compounds of copper(II) and nickel(II) with bidentate nitrogen-containing organic ligands. The gas-chromatographic method was used to study the thermodynamic characteristics of the adsorption of organic compounds belonging to various classes on Silochrome S80 before and after its modification. It was found that supported metal complexes strongly affect the chromatographic polarity and favor a more selective separation of mixtures of close-boiling carbonyl compounds and saturated and unsaturated light hydrocarbons. |
