Abstract
Methods of removing impurities from an impurity-loaded organic salt solution by intermixing the impurity-loaded organic salt solution with a stripping solution to form a biphasic mixture, wherein the intermixing effectively reduces the concentration of impurities in the impurity-loaded organic salt, thereby removing impurities from the organic salt and forming an impurity-reduced organic salt solution phase and a stripping solution phase are provided herein.
