ABSTRACT : Mixtures of aliphatic carboxylic acids and iorganic anions were determined by ion-exclusion chromatography. A range of sulfonic acid eluents were examined using UV absorption and conductivity detection. Of the eluents studied, sodium octanesulfonate proved to be the optimum. The aliphatic carboxylic acids were found to elute in the order of increasing carbon number. the retention of these solutes was controlled by a combination of ion-exclusion through the Donnan potential and hydrophobic interactions. Detection limits obtained were in the range of 0.71-100 ppm. Sulfonic acid eleunts were found to be suitable for the determination of mixtures of aliphanic carboxylic acids and inorganic anions. 56
