摘要：

As local adsorption isotherm theta(t) changes with time, it induces a changing with it of both, the net experimental adsorption rate partial derivativetheta(t)/partial derivativet with lateral molecular interaction, as well as the rate constants for adsorption (k(a)) and desorption (k(d)). All these changes are experimentally measured by applying the reversed-flow gas chromatographic method, and a relatively simple equation. These calculations have been applied to the adsorption of dimethyl sulfide on pieces of Penteli marble at 373 K and to the adsorption of heptane on gamma-alumina at 383 K.
