TLDR
A chelating ion exchange phenol-formaldehyde polymer, poly(salicylaldoxime 3,5-diylmethylene) was synthesized and characterized as mentioned in this paper.Abstract:
A chelating ion-exchange phenol-formaldehyde polymer, poly(salicylaldoxime 3,5-diylmethylene) was synthesized and characterized. The sorption properties of the chelate-forming resin towards various divalent ions (Mg 2+ , Ca 2+ , Ni 2+ , Cu 2+ , Zn 2+ and Cd 2+ ) were studied by a static batch equilibration technique as a function of pH and contact time. The resin exhibited high selectivity towards Cu 2+ ions and showed fast rates of metal ion uptake, particularly for Cu 2+ which experienced >90% uptake in less than 1 h. In a dynamic column operation, it was demonstrated that the resin can be used for effective removal of copper ions from aqueous solutions.read more
