Anion Effects In The Extraction Of Metal Ions Into Room-Temperature Ionic Liquids (Rtils), Sarah Lynn Garvey

Theses and Dissertations

As part of a broader program directed at the development of improved approaches to the removal of actinides and heat-producing fission products from spent nuclear fuel, the fundamental aspects of the partitioning of selected metal ions between aqueous solution and various room-temperature ionic liquids (ILs) containing a neutral extractant have been investigated.

Prior work has shown that in contrast to the partitioning of alkaline earth cations into conventional solvents in the presence of a crown ether, which is known to proceed via a single pathway (i.e., neutral complex extraction), their extraction into an IL is often a complex, multi-path process …
