Andronikashvili, L. Eprikashvili, N. Pirtskhalava, M. Zautashvili] A selective adsorbent was proposed on the basis of synthetic zeolite silikalit-2 modified with cadmium, tallium, and silver cations. It is intended for the gas chromatographic separation of some isomeric benzene derivatives. The adsorbent possesses pronounced retention properties to para isomers of aromatic compounds, which is due to the molecular sieve properties of the zeolite and the ability of benzene derivatives to form unstable complexes with cations entering the composition of the zeolite. Low selectivity to ortho and meta isomers is due to only the complexation effect. Pleiades Publishing, Ltd., 2007 Andronikashvili T.
