    摘要： To provide a method for recovering an anionic fluorinated emulsifier, whereby an anionic fluorinated emulsifier adsorbed on a basic ion exchange resin can be simply and efficiently recovered. A mixed liquid of an aqueous inorganic acid solution, a fluorinated medium and a non-fluorinated medium, is contacted to a basic ion exchange resin having an anionic fluorinated emulsifier adsorbed thereon, to recover a liquid phase containing the fluorinated medium, or an aqueous inorganic acid solution is contacted to a basic ion exchange resin having an anionic fluorinated emulsifier adsorbed thereon, then a mixed liquid of a fluorinated medium and a non-fluorinated medium is contacted thereto, and thereafter the basic ion exchange resin and a liquid phase are separated to recover the liquid phase, whereupon from each liquid phase, an acid of the anionic fluorinated emulsifier is recovered.
