Method for regenerating anion exchange resin

The invention relates to the field of ion exchange resin regeneration and provides a method for regenerating anion exchange resin. The method comprises the steps of putting the anion exchange resin to be regenerated into a glass chromatographic column at the temperature of 5-50 DEG C through a wet-process column packing method, wherein the diameter-height ratio is 1: 2-1: 8, making 0.5-8 BV of an alcohol-alkaline solution pass through an anion exchange column, conducting washing till PH is not higher than 9, then making 0.5-6 BV of a hydrochloric acid solution pass through the anion exchange column, conducting washing till PH is not lower than 5, finally, making 0.5-6 BV of a sodium hydroxide solution pass through the anion exchange column, and conducting washing till PH is not higher than 9, so that regeneration of the anion exchange resin is completed. By means of the method, defects of existing anion exchange resin regeneration methods in stevioside production are overcome, the regeneration exchange capacity of the anion exchange resin is greatly improved, the handling capacity is remarkably increased, and the regeneration cycle is longer.
