Surface-grafted Europium and Erbium Complexes of the 12-Tungstosilicate Heteropolyoxometalate: A Synthetic and Structural Investigations
The hydrothermal synthesis of two new inorganic-organic hybrid materials in which PDA (PDA = 1,10-phenanthroline-2,9-dicarboxylate) is connected to a well-defined Keggin-type polyoxometalate anion (POM) and a Ln(III) cation (POM = [SiW12O40]4−; Ln = Eu3+ (1), Er3+ (2)), are reported. These hybrids are characterized by elemental analyses, IR spectra and single-crystal X-ray diffraction. Single-c...
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...
متن کاملDetermination of samarium (III) ions in environmental samples after magnetic solid phase extraction using 1, 10- phenanthroline-2, 9-dicarboxilic acid modified Fe3O4/GO nanosheets
There is a growing interest in the development of new methods for extraction of REEs from nuclear wastes.In this study, we fabricated a novel material composed of 1,10-phenanthroline-2,9-dicarboxilic acid (PDA)functionalized magnetic graphene oxide (Fe3O4/GO) for extraction of Sm(III) from aqueous solutions. Ourinterest in selection of carboxyl-containing ligand was due to its...
متن کاملPreparation and quality control of 153Sm-[tris(1,10 -phenanthroline) samarium (III)] complex
Background: The 153Sm-[tris(1,10-phenanthroline) Samarium(III)]complex (153Sm-PL3) was prepared in view of development of targeting therapeutic compounds for malignancies, and interesting in-vitro anti-tumor activities of lanthanide phenanthroline complexes,. Materials and Methods: Sm-153 chloride was obtained by thermal neutron flux (4 × 1013 n.cm-2.s-1) of enriched 152Sm2O3 sample, diss...
متن کامل2,9-Dicarbonyl-1,10-phenanthroline derivatives with an unprecedented Am(III)/Eu(III) selectivity under highly acidic conditions.
Four lipophilic 1,10-phenanthroline di(thio)amide, diester or diketone derivatives were studied as ligands for Am(III)/Eu(III) separation from acidic media. The synthesis of these compounds is reported together with the extraction tests in different solvents (kerosene, octanol and o-nitrophenyl hexyl ether), HNO3 concentrations and ratios between the ligand and the synergistic agent (Br-Cosan)....
