Turned gas chromatographic investigation of porous polymer Dowex l-285 sorption properties

Abstract

Sorption properties of porous polymer Dowex L-285 were investigated. Sorption isotherms of
different classes organic compounds were drawing, thermodynamic functions of sorption were calculated.
It is determined, that retention volumes have linear dependence with ejected substance quantity, in cause
of strong interactions between sorbats on polymer surface. Sorbent polarity was estimated by linear
decomposition of retention parameters (LDRP) method. It is determined, that Dowex L-285 is a low-polar
sorbent and could be relate to third type of Kiselev classification
