METHOD OF RECOVERING FLUOROCHEMICAL SURFACTANT |
| 摘要 |
A method of more efficiently recovering a fluorochemical surfactant from an aqueous solution containing the surfactant. The method of recovering a fluorochemical surfactant comprises subjecting an aqueous solution containing the surfactant to a filtration treatment with a reverse osmosis membrane to obtain from the aqueous solution a concentrated aqueous solution of the fluorochemical surfactant.
