Title:
ADJUSTMENT METHOD OF CATION EXCHANGE RESIN
Document Type and Number:
Japanese Patent JP2023009490
Kind Code:
A
Abstract:
To provide an adjustment method of a weakly acidic cation exchange resin capable of reducing a washing period after performing a regeneration process of an H type weakly acidic cation exchange resin.SOLUTION: There is provided an adjustment method of a cation exchange resin comprising: a regeneration process for bringing an acid aqueous solution into a cation exchange resin, for converting the cation exchange resin into an H type; and a washing process for bringing washing water into contact with the H type cation exchange resin converted into the H type, for washing the H type cation exchange resin, in which the cation exchange resin is a weakly acidic cation exchange resin, and a normality of the acid aqueous solution is 0.10 to 0.50 N.SELECTED DRAWING: None
