Abstract

A standard weak acid electron exchanger based on hydroquinone phenol formaldehyde (HPF) has been prepared by standard procedure [L. K. Edward and P. W. Richard, Chem. Abstr., 49, 7780b (1955)]. Similarly, three new electron exchangers based on hydroquinone, polyvinyl alcohol, formaldehyde, and acrylonitrile (HPFA) have been synthesized and compared with the standard HPF electron exchanger.
