摘要：

Conducting polymer composite membranes with a separation layer of polypyrrole doped with hexafluorophosphate (PF6-) and p-toluenesulfonate (CH3C6H4SO3-), were examined for the removal of methanol from organic solvents (toluene, IPA, MTBE and acetonitrile) by pervaporation. In all the cases, both membranes displayed preferential permeation of methanol. Selectivities and permeation rates as functions of methanol content were studied. The highest selectivity to methanol over toluene, accompanying an acceptable methanol flux, was obtained with the membrane doped by PF6-.
