Room temperature ionic liquids (RTILs) have potential throughout the nuclear industry in the recovery and purification of actinide elements, as reactor components, as waste disposal forms, and potentially as media for the storage and/or separation of spent nuclear fuels. Due to their unique dissolution properties, RTILs can be used as substitutes for solvents currently used in the extraction of uranium from native ores, and in the dissolution and reprocessing of spent nuclear fuels. Research efforts in our laboratory focus on determining the chemical properties (i.e., solubility, complexation, redox properties, etc.) of actinide species in RTIL systems. We are currently involved in RTIL projects ranging from the spectroscopic characterization of actinide complexes by O[sup 17]NMR, low temperature UV-Vis, and EXAFS, to the enhanced dissolution and separation of actinide oxides in room temperature ionic liquids. © 2000 American Institute of Physics.

Herein we propose that many reaction outcomes in ionic liquids may be explained by...
