Abstract
To provide an adjustment method of a boron selective anion exchange resin capable of reducing a period of washing, after performing a regeneration process of an OH type boron selective anion exchange resin.SOLUTION: There is provided an adjustment method of an anion exchange resin comprising: a regeneration process for bringing an alkali metal hydroxide aqueous solution into contact with an anion exchange resin, for converting the anion exchange resin into an OH type; and a washing process for bringing washing water into contact with the OH type anion exchange resin converted into the OH type, for washing the OH type anion exchange resin, in which the anion exchange resin has a glucamine group as an ion exchange group, and a normality of the alkali metal hydroxide aqueous solution is 0.01 to 0.50 N.SELECTED DRAWING: None
