✦ Synopsis

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.
