Retention Characteristics of Inorganic Salts and Polyethylene Glycols on Polysulfones

Abstract

Polysulfone interfacial properties were determined using HPLC. the equilibrium distribution coefficients for a series of inorganic salts as well as a series of poly-ethylene glycols with different molecular weights are presented. the difference in solute-polymer interactions are explained in terms of differences in the polymer structure. Hansen's solubility parameter was used to quantify this difference in polymer structure.
