Abstract

Provided is a method for recovering an anionic fluorinated emulsifier enabling an anionic fluorinated emulsifier onto which a basic ion exchange resin has been adsorbed to be recovered easily and efficiently. A basic ion exchange resin adsorbed onto an anionic fluorinated emulsifier is brought into contact with a mixture of an inorganic acid aqueous solution a fluorinated medium and a non fluorinated medium and a liquid phase containing a fluorinated medium is recovered; or a basic ion exchange resin adsorbed on an anionic fluorinated emulsifier is brought into contact with an inorganic acid aqueous solution and then brought into contact with a mixture of a fluorinated medium and a non fluorinated medium whereupon the basic ion exchange resin and the liquid phase are separated and the liquid phase is recovered; and an acid of the anionic fluorinated emulsifier is recovered from the liquid phases.
