This paper describes enzyme, coupled transport and redox reaction-driven transport membranes, in which the transport process accompanies a specific chemical reaction. For the enzyme membrane, the kinetic behavior of β-glucosidase immobilized in a collagen membrane is discussed from the transport rates of<I>p</I>-nitrophenyl-β-D-glucopyranoside and its reaction product, <I>p</I>-nitrophenol. In the coupled transport, two types of liquid membranes capable of concentrating picrate or metal ions are described. The first is a carrier-containing membrane : the rate of transport of the permeant ions is proportional to the carrier concentration in the membrane. The second is a carrier-free membrane, which is supported by a micro-porous polymer film. For the redox reaction-driven transport membrane, the uphill transport of picrate and potassium ions is described.
