Abstract:Tributyl phosphate and N,N-di(2-ethylhexyl)isobutyramide
(DEHiBA) are uranium-selective extractants that could be used to recover
low-enriched uranium from commercial used nuclear fuel. The economic
viability of liquid–liquid extraction processes for chemical
separations depends on both thermodynamic and kinetic considerations.
We used microfluidic droplet extraction to measure interfacial phase
transfer rate constants for the extraction and stripping of Ce(IV),
a nonradioactive actinide surrogate. The Damköh… Show more
