Pervaporation was conducted with a microporous SiO 2 -ZrO 2 membrane at 50 and 75 o C for separation of aqueous solutions of organic solvents such as acetone, isopropyl alcohol (IPA) and dioxane. The SiO 2 -ZrO 2 membrane showed quite high fluxes of around 300 mol/(m 2 h) with large separation factors of 3800 for dioxane/water mixture and of 2800 for...
