Hydrogen chloride is stripped from spent basic ion exchange resin by treatment with a solution of a tertiary amine in an amide solvent. The eluent solution is treated with anhydrous ammonia to precipitate ammonium chloride. The solution of tertiary amine in amide solvent is separated from the precipitate and may be used to regenerate spent resin.
