    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. An aqueous inorganic acid solution and an organic solvent having a nitrile group are contacted to a basic ion exchange resin having an anionic fluorinated emulsifier adsorbed thereon, to recover a liquid phase containing the anionic fluorinated emulsifier, or an aqueous inorganic acid solution is contacted to a basic ion exchange resin having an anionic fluorinated emulsifier adsorbed thereon, then an organic solvent having a nitrile group is contacted thereto, and thereafter the basic ion exchange resin and a liquid phase are separated to recover the liquid phase, whereupon from the liquid phase, an acid of the anionic fluorinated emulsifier is recovered.

    摘要: The present invention relates to a simulated moving bed process, wherein at least one adsorbent is washed after binding of target compound and wherein the outlet of wash liquid from said adsorbent is subsequently passed onto another adsorbent for binding of target compound removed by said washing. In one embodiment, the method comprises binding of at least one target compound using three or more adsorbents connected in series and elution of target compound from said three adsorbents. After the binding to an adsorbent, wash liquid is passed across said adsorbent to recover desorbed and/or unbound target compound, and the outlet of such wash liquid is directed to the adsorbent after the next in the series, to which no feed has yet been added. The target compound is recovered by eluting target compound from the washed adsorbents.
