Abstract
In a method for separating and regenerating a mixed bed of exhausted anion and cation resins and for removing metallic foulants from the mixed bed, substantially all of the cation and anion resins in the bed are separated by their respective buoyancies and metallic foulants are displaced from the resins using an amine salt solution having a density between the densities of the anion and cation resins. A composition formed during this method comprises the anion resin, the metallic foulants, the cation resin, and the amine salt solution.
