Dynamically Formed Hydrous Zirconium (IV) Oxide-Polyelectrolyte Membranes. V. Non-Homogeneous Poly (Acrylic Acid-Covinyl Alcohol) Membranes: Rejection and Flux Properties and the Treatment of Coal Gasification Waste Water
A non-homogeneous poly(acrylic acid-covinyl alcohol) copolymer (I) was synthesized. This copolymer was used as polyelectrolyte in a dynamically formed hydrous zirconium (IV) oxide-polyelectrolyte membrane. The resultant Zr(I) membrane gave salt rejection figures exceeding 99% and flux values of 2500 lmd. A set of these Zr(I) membranes was used to treat a coal gasification wastewater in a laboratory experiment, and the membranes rejected a wide variety of constituents satisfactorily. © 1989.
