Abstract
ABSTRACTThree experimental techniques were employed to determine the partition coefficient (K) of toluene, d‐limonene, and ethyl acetate between water and polystyrene. These techniques were gas chromatography, (GC) gel permeation chromatography (a novel approach), and a dynamic thermal stripping‐thermal desorption procedure. Comparative results of K values, range of applicability and the limitations of each technique were determined. GC was very suitable for systems showing high K values, while gel permeation chromatography was excellent for direct measurement of sorbed compounds. Statistical analysis of results and kinetics of the sorption process were included. Values of K were 800 for toluene, 5100 for d‐limonene and 1.9 for ethyl acetate.
