FIELD: chemistry.
SUBSTANCE: invention relates to methods of regenerating ionites. A basic anion exchange resin on which a fluorinated emulsifying agent is adsorbed is brought into contact with an aqueous solution of an alkali metal hydroxide at 60-105°C, where the said solution does not contain organic solvents.
EFFECT: invention provides an efficient method of regenerating a basic anion exchange resin in which there is no need to ensure safety of the regeneration technique, and expenses on realising the method are lowered.
