Anion exchange resin solvent selectivity and anion solvation: a nuclear magnetic resonance study

Nuclear magnetic resonance has been utilized to study solvent selectivity of anion exchange resins in aqueous dimethyl sulfoxide and aqueous acetonitrile. Solvent selectivity data in the chloride ionic form is in qualitative agreement with independent preferential solvation studies of chloride ion. The importance of solvent activity coefficients is demonstrated for aqueous acetonitrile.
