Abstract: A method for removing chloride ions from an anion exchange resin to provide extremely low residual chloride concentration and comprises placing the resin in a cathode cell of an electrolytic cell, the electrolytic cell having an anode and a cathode, and anode and cathode cells being separated by an anion selective permeable membrane. Catholyte is flowed through the resin containing cathode cell and anolyte is flowed through the anode cell while a direct current is applied across the anode and cathode. Chloride or chlorine gas derived from the resin is removed from the anode cell.
