Abstract
PURPOSE: To regenerate ion exchange resins with good efficiency by passing a sulfuric acid used for regeneration of the cation exchange resin through the strong basic anion exchange resin, and regenerating the same with a sodium hydroxide soln.
CONSTITUTION: At the time of regenerating ion exchange resins, the cation exchange resin is regenerated with a sulfuric acid soln., and the whole or part of this waste liquid of regeneration is contacted with the strong basic anion exchange resin. Then, the Cl form of the strong basic anion exchange resin once assumes CO3 form or SO4 form. Thereafter, this anion exchange resin is regenerated with a sodium hydroxide soln. If the resins are regenerated in this way, the efficiency of regeneration is excellent and the amount of regenerating agents can be less.
