| Abstract: | Abstract A phenol-formaldehyde polymer, poly(salicylaldehyde 3,5-diylmethylene) was synthesized and characterized. A chelating ionexchange resin was obtained by reacting the polymer with nbutylamine. The chelation characteristics of the chelate-forming resin was studied by a batch equilibration technique. The resin showed fast rates of metal ion uptake and was found to selectively chelate Cu2+ and Cd2+ ions with capacities up to 3.56 mmol/g over a pH range of 5–8. |
