Comparison of the Extraction as a Function of Time in two GANEX solvents -Influence of Metal Loading, Interfacial Tension and Density
Artikel i vetenskaplig tidskrift, 2013

Two Group ActiNide EXtraction solvents for the extraction of actinides from used nuclear fuel for transmutation purpose have been compared. The solvent studied more precisely comprises cyclohexanone, tributylphosphate and a molecule from the bis-triazine bi-pyridine family, while the alternative utilizes di-ethyl-hexyl butyramide instead of tributylphospate. The focus of the comparison has been on the kinetics of the extraction of americium and europium, and the influence of an increased metal content on their separation factor. Both systems showed to maintain the equilibrium separation factor up to an europium concentration of 1 mM and their SFAm/Eu is decreased with a prolonged phase contact.
