Abstract

Measurements were made of uptakes of acetic acid and water from aqueous solution onto basic polymer sorbents. Sorption equilibria were interpreted through a chemical complexation model, yielding sorption affinities and saturation capacities for acetic acid. Basicity scales, such as pKa and Gutmann donor number (DN), based upon the monomeric functional group chemistry were shown to explain the trends in sorption affinities. Solvent leaching was investigated as a means of regenerating the sorbents. It was found that regeneration can be improved by using solvents of high donicity. Aqueous ammonia proved to be effective for regenerating moderately strong base sorbents.
