Method for recovering fluorine-containing emulsifier |
| abstract |
(57) [Problem] To provide a method capable of recovering a fluorine-containing emulsifier contained in exhaust gas from a drying / heat treatment process of a fluorine-containing polymer at a high recovery rate. SOLUTION: The pH of a fluorine-containing polymer containing a fluorine-containing emulsifier obtained by emulsion polymerization or aqueous dispersion polymerization in an aqueous medium containing a fluorine-containing emulsifier is measured by using an exhaust gas in the drying step and / or heat treatment step and an alkali. 7 to 12 The fluorine-containing emulsifier is absorbed into the alkaline aqueous solution by contacting with an aqueous solution adjusted to less than that to form a layered double hydroxide in the fluorine-containing emulsifier-containing aqueous solution, and the fluorine-containing emulsifier is interposed between the layers. Fix and collect. |
