摘要：
The adsorption of methyl linoleate and methyl oleate on sepiolite has been studied by pulse-response chromatography using the theory of the statistical moments. The adsorption equilibrium constants of the two compounds were determined at 453, 463 and 473 K, together with their heats of adsorption. The results showed that both compounds have a different degree of adsorption, depending on the number of unsaturated bonds in the molecule.
