| Abstract: | Benzene/cyclohexane mixture is separated via supported liquid membranes filled with AgNO3,AgBF4 and various ionic liquids.The effects of ionic liquid and silver salt species in the supported Ag+/ionic liquid membranes,concentration of benzene in feed and the operating temperature of the separation process on the permeability and selectivity of supported Ag+/ionic liquid membranes were studied respectively.The results show that the membrane filled with AgNO3/[bmim][BF4]exhibits a good separation performance for benzene/cyclohexane mixture, the membrane permeation flux is 14.81 g/（m2·h） and separation factor is 36.59. |
