摘要：
The thermodynamic characteristics of sorption of adamantane and its derivatives on a mixed stationary phase consisting of a graphite-like solid substrate, polyethylene glycol, and beta-cyclodextrin (beta CD) were determined by gas chromatography. The introduction of beta-CD additives to a polar polymer matrix was shown to considerably decrease the chromatographic retention of the sorbates, which is evidence of the macrocyclic effect. The presence of beta-CD molecules was found to increase the selective properties of the mixed sorbent with respect to the structural isomers of adamantanes.
