Liquid membrane technology is introduced and is identified as a subset of membrane science. A tutorial section discusses configurations, transport mechanisms, experimental techniques, and a survey of basic theoretical approaches. The concepts of reactive liquid membranes which combine traditional unit operations such as extraction or absorption with stripping are discussed. The chapters to follow in this volume are summarized and the subject of each is placed in perspective to the field of liquid membrane technology. TutorialA membrane can be viewed as a semi-permeable barrier between two phases. This barrier can restrict the movement of molecules across it in a very specific manner. The membrane must act as a barrier between phases to prevent intimate contact. The semi-permeable nature is essential to insuring that a separation takes place.There are two points to note concerning this definition. First, a membrane is defined based on what it does, not what it is. Secondly, a membrane separation is a rate process. The separation is accomplished by a driving force, not by equilibrium between phases (JO.By extending our definition of a membrane, we can include liquids. If we view a membrane as a semipermeable barrier between two phases, then an immiscible liquid can serve as a membrane between two liquid or gas phases. Different solutes will have different solubilities and diffusion coefficients in a liquid. The product of these two terms is a measure of the permeability. A liquid can yield selective permeabilities and, therefore, a separation. Because the diffusion coefficients in liquids are typically orders of magnitude higher than in polymers, a larger flux can be obtained.
