Abstract: Anionic exchange resins exhibiting a reduced syrup refining capacity are rejuvenated to a useful state by treating the anionic exchange resins at a temperature of at least 170* F. with a concentrated acid solution for a period of time and under conditions sufficient to remove therefrom the occluded organic impurities which interfere with its anionic exchange capacity.
