چکیده انگلیسی
Ion-exchange can be used for primary recovery of aqueous dicarboxylic acids at neutral pH, where there is almost complete acid dissociation. The equilibria of anion exchange of aqueous dicarboxylate anions (fumarate, itaconate, malate and succinate) with anions (Clâ and OHâ) bound to quaternary ammonium compounds (Aliquat extractant and Dowex sorbent) were quantified. All equilibria could be described by the same model. The four dicarboxylates behaved similarly, and were exchanged by two Clâ or OHâ anions. Sorption gave a much better exchange than extraction and OHâ gave a much better exchange than Clâ. In batch equilibrium experiments most Clâ is not exchanged by dicarboxylate, pointing at the importance of column operation.
