“…Plutonium is one among many toxic materials that have to be completely removed from the process effluents of a nuclear facility, to minimize the associated risks. Solvent extraction, ion-exchange and sorption are the most important ways, to recover and concentrate metal ion from their dilute solutions [3,4]. Most of the bulk separation methods in hydrometallurgical processes generally employ solvent extraction technique, owing to its high efficiency, reflected in terms of fast kinetics, selectivity, simplicity and throughput.…”

The extractant-impregnated polymeric beads (EIPBs), containing polyethersulfone as base polymer and 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester (PC-88A) as an extractant, were prepared by phase inversion method. These EIPBs were characterized by FTIR, TGA and SEM techniques. The beads were found to have excellent acid stability, since these did not exhibit any structural deformation or loss of the extractant into aqueous nitric acid solution (6 M), for a period of 15 d. The feasibility of Pu(IV) extraction, using these beads, from nitric acid solution was tested by batch equilibration method. Parametric dependence of Pu(IV) extraction on experimental variables, like strength of nitric acid, equilibration time, Pu(IV) concentration, etc., was investigated. The present study also addressed the important practical issues, like maximum loading capacity and the reusability of these beads. Under optimized conditions, equilibrium capacity and maximum loading capacity for Pu(IV) were found to be 2.03 and 7.50 mg per gram of the swollen beads, respectively. The reusability of the beads was also ascertained by repetitive extraction-stripping of Pu(IV) up to 7 cycles of operation, without significant change in their extraction performance. The extraction of Pu(IV) by the blank polymeric beads was observed to be almost negligible, under the similar experimental conditions.

Reviews of aqueous processing in JOM have traditionally focused on hydrometa llurgical process routes. This article, however, addresses the application of aqueous processing in materials engineeri ng and presents some promi sing developments that employ aqueous-based routes for th e manufacture of high-tech componen ts and specialty products. Such applications include producing metallic and ceramic powders; etching; surface modification by electroplating and electro less plating; manufacturing jewelry and intrica te componen ts by elec troforming; and producing advanced cerami cs, composites, and nanophase materi als by sol-gel and biomimetic processing.18
