METHOD OF SEPARATING ANIONIC FLUOROCHEMICAL SURFACTANT |
摘要 |
Separation of an anionic fluorochemical surfactant from an aqueous solution containing the anionic fluorochemical surfactant is carried out by i) contacting the aqueous solution with a basic anion-exchange resin so that the anionic fluorochemical surfactant is adsorbed on the resin, and ii) eluting the anionic fluorochemical surfactant adsorbed on the resin with an eluent which is an alkaline solution containing water and an organic solvent. |
