Selective separation and determination of uranium in calcite and gypsum after EDTA-mediated sample dissolution and cation-exchange
(2019)
The present paper describes a relatively simple, effective, very selective and economic method for the determination of uranium in calcite and (phospho)gypsum samples. The analysis is performed by alpha-spectroscopy after ...
U(VI) adsorption by biochar fiber–MnO2 composites
(2019)
The removal of U(VI) by biochar fibers from aqueous solutions has been investigated prior and after MnO2 surface-deposition. The removal efficiency has been studied as a function of pH, U(VI) concentration, ionic strength, ...
Recovery of uranium from phosphate rock with EDTA-mediated dissolution and cation exchange
(2019)
The present study describes an alternative, environmentally friendly, simple, and material- and cost-effective process for the selective separation and recovery of uranium from phosphate rocks by cation-exchange using an ...
Novel binuclear antimony(III) halide complexes of 5-methoxy-2-mercaptobenzimidazole: synthesis, structural characterization, and biological studies
(Taylor & Francis Group, 2020-02-01)
The new binuclear antimony(III) complexes corresponding to the formulas [SbCl3(µ2-S)(MtMBZIM)2]2 (1), {[SbBr2(µ2-Br)(MtMBZIM)2]2·H2O} (2) and {[SbI2(µ2-I)(MtMBZIM)2]2·H2O} (3) (MtMBZIM: 5-methoxy-2-mercaptobenzimidazole) ...
Dual emission in a ligand and metal co-doped lanthanide-organic framework: color tuning and temperature dependent luminescence
(MDPI AG, 2020-01-25)
In this study, we report the luminescence color tuning in the lanthanide metal-organic framework (LnMOF) ([La(bpdc)Cl(DMF)] (1); bpdc2− = [1,1′-biphenyl]-4,4′-dicarboxylate, DMF = N,N-dimethylformamide) by introducing dual ...
New metal-organic frameworks derived from pyridine-3,5-dicarboxylic acid: Structural diversity arising from the addition of templates into the reaction systems
(Royal Society of Chemistry, 2020-03-21)
A series of new compounds prepared from reactions of pyridine-3,5-dicarboxylic acid (PDCH2), bipositive d-metal ions (Cd2+, Zn2+, Co2+ and Cu2+) and various template molecules [1,3-propanediol (pdH2), diethanolamine (deaH3), ...
Water-stable 2-D Zr MOFs with exceptional UO22+ sorption capability
(Royal Society of Chemistry, 2019-12-02)
Two new 8-connected 2-D MOFs, UCY-13 and UCY-14, based on Zr6 secondary building units (SBUs) and angular dicarboxylate ligands are reported. UCY-13 and UCY-14 display remarkable stability in various types of aqueous media, ...
From 1D coordination polymers to metal organic frameworks by the use of 2-pyridyl oximes
(MDPI AG, 2020-09-14)
The synthesis and characterization of coordination polymers and metal-organic frameworks (MOFs) has attracted a significant interest over the last decades due to their fascinating physical properties, as well as their use ...
Antiproliferative activity and apoptosis induction, of organo-antimony(III)–copper(I) conjugates, against human breast cancer cells
(Springer Nature Switzerland AG., 2020-11-01)
Three known organo-antimony(III)–copper(I), mixed-metal small bioactive molecules (SBAMs) of formula [Cu(tpSb)3Cl] (1), [Cu2(tpSb)4Br2] (2) and [Cu2(tpSb)4I2] (3) (tpSb = triphenylstibine) were used for the clarification ...
