Abstract:
A method of separating an anionic fluorochemical surfactant from an aqueous solution containing the anionic fluorochemical surfactant, which comprises (i) bringing the aqueous solution into contact with a basic anion-exchange resin to adsorb the anionic fluorochemical surfactant onto the basic anion-exchange resin and (ii) subsequently eluting the anionic fluorochemical surfactant from the basic anion-exchange resin with an eluent which is an alkali solution comprising water and an organic solvent.
