Extraction thermodynamics of Am(III) and Eu(III) using CyMe4-BTBP in various organic diluents

On the Basic Extraction Properties of a Phenyl Trifluoromethyl Sulfone-Based GANEX System Containing CyMe4-BTBP and TBP

“…Similar results have been found for other GANEX systems studied using different diluents. [40,41] During a GANEX process, high extraction of the actinides alongside a low extraction of the fission products is desirable. In this study, inactive metals have been used as references for the actual fission products, and for a majority of the investigated fission products, a distribution ratio below 1 has been found ( Figure 9).…”

Effect of the diluent on the solvent extraction of neodymium(III) by bis(2-ethylhexyl)phosphoric acid (D2EHPA)

“…The effect of diluents on the solvent extraction of metal ions has been studied for copper(II) (Whewell et al, 1979;Wionczyk and Apostoluk, 1997;Tao and Nagaosa, 2003;Mitchell and Banks, 1969), cobalt(II) (Aly et al, 1979), nickel(II) (Rajab et al, 1987;Rezaei and Nedjate, 2003;Sun et al, 2000), iron(III) (Alguacil et al, 1987;Cai et al, 2016;Mountcastle et al, 1971), aluminium(III) (Bailey and Mahi, 1987), trivalent rare earths (Arichi et al, 2006;Cui et al, 2012;Dukov and Atanassova, 2003;El-Nadi, 2010;Pai et al, 1977;Rout et al, 2012), thorium (Siekierski, 1962), uranium (Sato et al, 1985;Shukla and Kedari, 1996) and trivalent actinides (Chiarizia and Horwitz, 1992;Ekberg et al, 2010Ekberg et al, , 2015. Lofstrom-Engdahl et al (2013, 2014a, 2014b, 2014c D2EHPA. The more polar diluents cyclohexanone, chloroform and 1-octanol exhibited the lowest distribution ratios.…”

Effect of diluent on the extraction of europium(iii) and americium(iii) with N,N,N′,N′-tetraoctyl diglycolamide (TODGA)

“…It was already shown in the past that diluent has a substantial effect on the outcome of the extraction with respect to both distribution ratios as well as separation factors between different elements. [6][7][8][9][10][11][12][13][14][15] Despite the strong experimental evidence of diluent effect, its full theoretical explanation is challenging and predictions are still very uncertain. Few theoretical explanations for the diluent effect were proposed.…”
