Abstract

A number of resins have been synthesized by reacting orthohydroxy acetophenone‐semicarbazone with substituted benzoic acid and formaldehyde in the presence of some acid and basic catalyst. The physicochemical properties of the resins have been reported. The ion exchange properties of the resins have been investigated. Influence of electrolytes on the metal uptake of Cu^2+^, Ni^2+^, Zn^2+^, Mg^2+^, and Mn^2+^ has been studied. The distribution of metal ions at different pH has also been reported. © 1992 John Wiley & Sons, Inc.
