To provide a method for recovering, from a liquid to be treated containing a fluorinated polymer and a fluorinated emulsifier, the fluorinated emulsifier easily and efficiently. A liquid to be treated containing a fluorinated polymer and a fluorinated emulsifier, and a strongly basic anion exchange resin having an ion exchange capacity of at most 1.0 eq/L and a water content of at least 60 mass%, are brought into contact with each other, so that the fluorinated emulsifier is adsorbed on the strongly basic anion exchange resin, whereby the fluorinated emulsifier is recovered from the liquid to be treated. |
