Abstract

Bifunctional resins having pyridinium and methyl ammonium-based dicationic groups, separated by a five carbon spacer, have been prepared by chemical modification of Reillex™ 402 poly(4-vinyl pyridine). Batch sorption studies carried out for the three resins (I, II, III), which differ by degree of functionalization and physical form, revealed very fast kinetics, with III having highest K D value (650 at 7.5 M). The capacity of III was 4.5 meq/g. The resin was selective for Pu sorption from nitric acid medium having assorted metal ions and the Pu content of resultant raffinate was below the disposal limit. Column experiments with III show fast loading and elution of Pu(IV).
