Homogeneous 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 (...
متن کاملExtractive 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...

In the title compound, [CoCl(C(12)H(8)N(2))(H(2)O)(3)]Cl·H(2)O, the Co(II) ion is coordinated by two N atoms from the 1,10-phenanthroline ligand [Co-N = 2.125 (6) and 2.146 (6) Å], one chloride ligand [Co-Cl = 2.459 (2)Å] and three water mol-ecules [Co-O = 2.070 (5)-2.105 (5)Å] in a distorted octa-hedral geometry. Inter-molecular O-H⋯Cl and O-H⋯O hydrogen bonds form an extensive three-dimension...

متن کاملBis[tris(phenanthroline-κ2 N,N′)cobalt(II)] undecatungsto(VI)vanado(V)phosphate dihydrate
In the title hydrated salt, [Co(C12H8N2)3]2[PVW11O40]·2H2O, the complete Kegggin ion is generated by crystallographic inversion symmetry, which imposes statistical disorder on the O atoms of its central PO4 group. The V atom is statistically disordered over all the metal sites of the anion. In the cation, the Co(2+) ion is coordinated by three bidentate 1,10-phenanthroline (phen) ligands, gener...
