COMPETITIVE FACILITATED TRANSPORT OF ACID GASES IN MODIFIED CARRIER MEMBRANES

摘要

1 INTRODUCTIONMany attempts to develop semipermeable membranes for gas separation have beendone over the past twenty years [1,2].However,it is still difficult to prepare apolymer film which makes certain gas separation processed within range of being econ-omically and technically feasible,since most polymeric materials are relativelyimpermeable to gases.Facilitated transport concept which was first proposed
