Abstract
A method is provided for removing an anion from an aqueous liquid, such as a fermentation broth. The aqueous broth is contacted with a water-immiscible ion exchange liquid to extract the anion from the broth. The anion exchange liquid is then back extracted with an aqueous phase, to remove the anion, preferably for other uses.
