Gas chromatography investigations of thermodynamics of adsorption of organic compound vapors on carbon adsorbent modified by [beta]-cyclodextrin derivatives

The adsorption of organic-compound vapors of various structures and polarities on carbon adsorbent modified by permethylated and perbenzylated β-cyclodextrin is investigated using gas chromatography. The obtained thermodynamic properties are compared for adsorption on initial carbon adsorbent and tw...

Description
Summary:The adsorption of organic-compound vapors of various structures and polarities on carbon adsorbent modified by permethylated and perbenzylated β-cyclodextrin is investigated using gas chromatography. The obtained thermodynamic properties are compared for adsorption on initial carbon adsorbent and two modified adsorbents. The influence of molecular structure of the studied sorbates and substituent groups in cyclodextrin molecules on adsorption is considered.[PUBLICATION ABSTRACT]
