Abstract
Permselective membranes comprising hydrazide-containing aromatic polymers complexed with selected metals that form square planar coordination complexes therewith; the membranes being prepared by reacting the polymer with a salt solution of the selected metal so that the metal is incorporated into the resulting membranes; the membranes being useful, among other things, for the reverse osmosis separation of a salt solute from an aqueous solvent.
