High Performance Liquid Chromatographic Studies of the Ion Exchange Selectivity of Nafion

Abstract

Nafion films were coated on 5 micron octadecyl-derivatized silica. HPLC columns were packed with this film-modified ODS and the ion exchange selectivity of Nafion was studied. A homologous series of organic cations was used to probe the ion exchange properties of Nafion. These studies show that Nafion has remarkable affinity for hydrophobic cations. The logs of the ion exchange selectivity coefficients for the cations of the homologous series were found to increase in a linear fashion with the molecular weight of the cation. (Author)
