説明
Abstract Stabilities of two types of supported liquid membrane (SLM), hollow fiber and flat sheet, have been studied in terms of the leakage of water across the membrane by using various kinds of polymeric solid supports and organic solvents. From lifetime data as a relative measure of SLM stability, it was found that the pore size of the support has the most significant effect on the stability. More stable membranes can be attained by use of membrane solvents with higher interfacial tension, and therefore of aliphatic hydrocarbons of higher boiling point; aromatics show a trend to be simply washed or forced sout of the SLM. In practical SLM separations, a membrane solution containing a surface-active carrier reduces the stability of the SLM by lowering the solvent-water interfacial tension. Membrane liquids held within the pores of a polymeric solid with lower surface energy may be more sensitive to variation of the interfacial tension.
