The structure of hydrous Zr(IV) oxide–polyacrylate membranes: Poly(acrylic acid) deposition
Research sponsored by the Energy Research and Development Administration under contract with Union Carbide Corporation.
Abstract
The formation of hydrous Zr(IV) oxide–polyacrylate dynamic membranes was studied by the dependence of water flux decline and steady-state water flux on the concentration of poly(acrylic acid) in the feed. Analysis of the results indicates that the poly(acrylic acid) enters the pores of the hydrous Zr(IV) oxide layer, rather than forming a second layer. This configuration was consistent with scanning electron micrographs of the surface.
