Sol-Gel Derived Poly (Vinyl Alcohol) Maleic Acid/Silica Hybrid Membrane for Desalination by Pervaporation

摘要

In recent years, membrane desalination using reverse osmosis (RO) has been the leading candidate technology for supplying fresh water. A new type of PVA/MA/silica hybrid membrane has been synthesised via a sol-gel route and a solution casting method. The pervaporation separation of aqueous salt solution of hybrid PVA/MA/silica membranes was examined in relation to the diffusion coefficient of water.
