Abstract
Resin (RPPBD) prepared by Friedel-Craft's polycondensation of 2,4-dihydroxypropiophenone with 1,4-butane diol in the presence of polyphosphoric acid catalyst proved to be a selective ion-exchange resin and indicates coordination tendency for some metal ions. The resin was characterized by elemental analysis, IR spectra, viscosity study and its number average molecular mass () was determined by non-aqueous titration and found to be 2475 g/mol. Chelation ion-exchange properties of this resin have also been studied employing batch equilibration method. It was employed to study selectivity of metal ion uptake over a wide ph range and in media of various ionic strength. The overall rate of metal uptake follows the order: UO22+ > Fe2+ > Cu2+ > Ni2+
