  Disclosed are an adsorption process whereby a fluorocarboxylic acid having an ether bond can be adsorbed to a high extent by using active carbon without changing the form thereof, and a desorption process whereby the adsorbed material can be desorbed from the active carbon to thereby enable the reuse of the active carbon and the adsorbed material. In the aforesaid processes, a solution containing a fluorocarboxylic acid having an ether bond is contacted with active carbon and thus the active carbon is allowed to adsorb the fluorocarboxylic acid, to thereby give a solution having a small fluorocarboxylic acid content. Then, the active carbon having adsorbed the fluorocarboxylic acid is heated to thereby desorbs the fluorocarboxylic acid from the active carbon.

  本发明涉及一种吸附过程，通过使用活性炭可以高度吸附具有醚键的氟碳羧酸，而不改变其形式，并且一种解吸过程，通过从活性炭中解吸被吸附的材料，从而使活性炭和被吸附的材料可以重新使用。在上述过程中，将含有具有醚键的氟碳羧酸的溶液与活性炭接触，从而允许活性炭吸附氟碳羧酸，从而给出具有小氟碳羧酸含量的溶液。然后，加热吸附氟碳羧酸的活性炭，从而从活性炭中解吸氟碳羧酸。

  The present invention aims to provide a method of producing a fluoropolymer aqueous dispersion having a significantly small particle size and excellent dispersion stability without using a long-chain fluorosurfactant. The present invention relates to a method of producing an aqueous dispersion containing at least one fluoropolymer selected from the group consisting of polytetrafluoroethylene and melt-processible fluororesins excluding polytetrafluoroethylene. The method includes polymerizing a fluoromonomer in an aqueous medium in the presence of a fluorosurfactant having a Log POW value of not higher than 3.4 and a polymerization initiator. The amount of the fluorosurfactant corresponds to 4600 to 500000 ppm of the aqueous medium.
