A new concept of polymeric reversed micellar extraction was proposed on the basis of poly-meric micellar extraction and reversed micellar extraction. Various PPO-PEO copolymers with different PPO content( 60%～100%) and organic solvent were used to form polymeric reversed micellar solutions

which were subsequently used to extract phenol from dilute solutions. The results showed that the partition coefficient increased with the increase of PPO content in polymers. Overall mass transfer coeffi-cient reached its peak at PPO content of 80% . Both partition coefficient and overall mass transfer coefficient increased with the increase of polymer concentration. The addition of a cosurfactant can improve solubilization in polymeric reversed micelles.
