Inverse gas chromatographic characterization of Porapak Q as an extractant of pollutants from aqueous media
Keyword(s):
AbstractThe surface of Porapak Q was characterized by inverse gas chromatography (IGC) carried out by the determination of dispersive and specific adsorption components of Porapak Q surface, calculating γsd and -ΔH as parameters, respectively. An interpretation was given based on the chemical structure of Porapak Q. The obtained results were confirmed through the surface Lewis acidity and basicity constants, K a and K b, respectively, correlating well with the determined thermodynamic parameters.
