Reverse osmosis separation of particular organic solvent mixtures by a perfluorodioxole copolymer membrane

Abstract Reverse osmosis (RO) separation of organic solvent mixtures where solvent molecular weights are , methanol - water, ethanol-water as well as individual phases of the immiscible mixture of NMP and the nonpolar solvent n-heptane were also studied. To improve understanding, permeation of pure water in reverse osmosis mode was also investigated.
