Application of M41S type mesoporous adsorbents in gas chromatography

Journal Title: Aparatura Badawcza i Dydaktycza - Year 2012, Vol 17, Issue 3

Abstract

Zeolites are fine porous sorbents widely used in the practice of gas chromatography for the separation of gas systems and mixtures of volatile organic compounds. However, capabilities of zeolites are limited because of small sized "entrance apertures" (~0,9 nm) that limitate of their application in the analysis of the organic compounds with significant molecular volumes and active functional groups. Synthesis of the mesoporous materials with considerable sizes of the "entrance apertures" and retaining their molecular sieve properties as well open up new possibility of their application in gas adsorption chromatography for the separation of the mixtures consisting of the large molecules characterized with greater kinetic diameters (poly-nuclear aromatic compounds). Currently, the mesoporous materials of the M41S family have a greater application. The adsorption separation properties of new materials and their cationmodified forms were studied in different variants of the surface layer sorbents - mesoporous materials have been coated on the solid support Celite-545. Investigation of the chromatographic behavior of the M41S mesoporous adsorbent has shown that the benzene derivatives can be successfully separated on both initial and modified forms of the above ad-sorbent. This adsorbent and its modified forms may be applied as adsorbents in gas-chromatography for the analysis of difficult to separate mixtures of some polycyclic compounds.
