Abstract
1404399 Ion-exchange ILLINOIS WATER TREATMENT CO 10 April 1973 [10 April 1972] 17208/73 Heading B1J A process for the regeneration of an anion exchange resin having cation exchange resin admixed therewith, which comprises converting the anion exchange resin to the hydroxyl form with a sodium hydroxide solution, converting at least a part of the cation exchange resin admixed with the anion exchange resin to the ammonium form with an ammonium hydroxide solution, and thereafter contacting the solution produced in the said conversion of the cation exchange resin with a second cation exchange resin in the ammonium form which has a greater affinity for sodium cations than for ammonium cations to provide an ammonium hydroxide solution substantially free of sodium cations. The ammonium hydroxide solution may be re-used. The second cationexchange resin may be separately regenerated. The process is applicable to incompletelyseparated anion-exchange resin from a mixed bed, such as a condensate polisher.
