Extractive Properties of Tri-n-octylphosphine Oxide Towards Thorium (IV) and Europium (III) Ions in Aqueous Nitrate Media
Phosphoryl containing ligand tri-n-octylphosphine oxide (TOPO) in dichloromethane has been used as an extracting agent for tetravalent thorium and trivalent europium ions from their 1 M sodium nitrates. The equilibrium data reveal that both ions are extracted as the complexes at 1:3 metal/ligand ratio. The values of conditional extraction equilibrium constant (Kex) show the superior extract...

متن کاملSolvent extraction of Gd(III) from perchlorate and nitrate media with mixtures of thenoyltrifluoroacetone and Benzo-15-Crown-5
The extraction of Gadolinium (Gd) from perchlorate and nitrate media in 1,2-dichloroethane(C2H4Cl2), carbon tetrachloride (CCl4) and chloroform (CHCl3) by mixtures of 2-thenoyltrifluoroacetone (HTTA) and a crown ether benzo-15-crown-5 (B15C5) is investigated.The composition of the extracted species is determined as Gd(TTA)3.nB15C5 (n=1 in nitratemedium and n=2 in perchlorate medium). The values...
متن کاملHomogeneous liquid-liquid extraction of uranium(VI) using tri-n-octylphosphine oxide.
A simple and efficient method for the selective separation and preconcentration of uranium(VI) using homogeneous liquid-liquid extraction was developed. Tri-n-octylphosphine oxide (TOPO) and tri-n-butylphosphate (TBP) were investigated as complexing ligands, and perfluorooctanoate ion (PFOA-) was applied as a phase separator agent under strongly acidic conditions. Under the optimal conditions (...
