2010-1-1  Liquid membrane processes are those involving a selective liquid membrane phase in which simultaneous extraction/stripping occurs. Separation is achieved by permeation of solute through this liquid phase from a feed phase to a receiving phase. The feed and receiving phases are normally miscible while the membrane phase is immiscible in both.
