Temperature effect on the synergistic solvent extraction of lanthanides with mixtures of thenoyltrifluoroacetone and trioctylamine

The synergistic solvent extraction of Pr, Gd and Yb with mixtures of thenoyltrifluoroacetone and trioctylamine in CCl 4, C 6H 6 and CHCl 3 at 288, 298, 308 and 318 K has been investigated. The values of the equilibrium constants have been calculated as well as the values of the thermodynamic parameters. The possible mechanisms of formation of the mixed complexes in the organic phase have been discussed.

Temperature effect on the solvent extraction of some lanthanides with thenoyltrifluoroacetone

The solvent extraction of Pr, Gd and Yb with thenoyltrifluoroacetone solutions in C6H6, CHCl3 and CCl4 at 288 K, 298 K, 308 K and 318 K has been investigated. The values of the equilibrium constant have been calculated as well as the values of the thermodynamic parameters ΔH, ΔS and ΔG. The temperature effect on the solvent extraction of lanthanides with thenoyltrifluoroacetone is discussed.

The Synergistic Extraction of Sm(NO3)3and Gd(NO3)3by a Mixture of Tributyl Phosphate and Aliquat 336 in AMSCO and Ammonium Nitrate Medium

Abstract The synergic extraction of Sm and Gd using a mixture of tri-butyl phosphate and Aliquat 336 is presented. The influence of diluents, salting out agents and acidity on the synergic extractions have been investigated. The separation factor of Sm and Gd was found to be larger than 3. This is one of the best systems for the separation of Sm and Gd. NH4NO3 was found to be extracted by pure TBP or pure Aliquat 336, but cannot be extracted by a mixture of TBP and Aliquat 336.
