Methods of gas Chromatographic determination of the partial isotherms on a real multiphase sorbent, and in particular, the isotherms of adsorption on an interface of a stationary liquid phase and solid adsorbent, were developed.
The characteristics of the adsorption processes can be found directly from the dependence of the contribution to retention on the concentration of the substance to be chromatographed in the carrier gas.
The isotherms were determined and the characteristics of the adsorption of p- and m-xylenes at the interface of diisooctyl sebacate and the dimethyldioctadecylammonium derivative of vermiculite and on an uncoated surface of the vermiculite derivative were measured.
