Synthesis and Screening of Modified 6,6′-Bis(5,5,8,8-tetramethyl-5,6,7,8-tetrahydrobenzo[<i>e</i>][1,2,4]triazin-3-yl)-2,2′-bipyridine Ligands for Actinide and Lanthanide Separation in Nuclear Waste Treatment
Effects of chloro and bromo substitution
at the 4-position of the pyridine ring of 6,6′-bisÂ(5,5,8,8-tetramethyl-5,6,7,8-tetrahydrobenzoÂ[<i>e</i>]Â[1,2,4]Âtriazin-3-yl)-2,2′-bipyridine (CyMe<sub>4</sub>-BTBP) have been studied with regard to the extraction of
AmÂ(III) from EuÂ(III) and CmÂ(III) from 0.1–3 M HNO<sub>3</sub>. Similarly to CyMe<sub>4</sub>-BTBP, a highly efficient (<i>D</i><sub>Am</sub> > 10 at 3 M HNO<sub>3</sub>) and selective
(SF<sub>Am/Eu</sub> > 100 at 3 M HNO<sub>3</sub>) extraction was
observed for Cl-CyMe<sub>4</sub>-BTBP and Br-CyMe<sub>4</sub>-BTBP
in 1-octanol but in the absence of a phase-transfer agent
