Zusammenfassung:
Using 0.1 m Na2SO4 and 0.1 m MgSO4 feed solutions, four composite membranes (HR-95, HR-98, FT-30, PEC-1000) and two asymmetric membranes (SOLROX SC-200, SC-1000) were characterized by the transport coefficients of the phenomenological relationships. Subsequently, also the transport coefficients of the membranes for ethanol and dioxane were determined using ethanol- and dioxane-water solutions, respectively. Finally, the rejections of organic compounds were determined at 25°C and at 50 at or 70 at, respectively, using binary and ternary aqueous organic feed solutions.
