Characterization of the uptake of aqueous Ni2+ ions on nanoparticles of zero-valent iron (nZVI)
This study investigates the fixation of aqueous Ni2+ ions by nanoparticles of zero-valent iron (nZVI) prepared using the borohydride reduction method. The uptake of Ni2+ was tested under various experimental conditions ...
Retention of aqueous Ba2+ ions by calcite and aragonite over a wide range of concentrations: Characterization of the uptake capacity, and kinetics of sorption and precipitate formation
(The Geochemical Society of Japan, 2007)
The uptake of aqueous Ba2+, ions by abiogenic calcite and aragonite was studied over a wide range of concentration; 1.0 × 101, 5.0 × 101, 1.0 × 102 5.0 × 102, 1.0 × 103, 5.0 × 104, and 1.0 × 104 mg/L. The uptake process ...
A new methodology for removal of boron from water by coal and fly ash
High levels of boron concentrations in water present a serious problem for domestic and agriculture utilizations. The recent EU drinking water directive defines an upper limit of 1 mgB/I. In addition, most crops are sensitive ...
A two-dimensional organic–inorganic hybrid compound, poly[(ethylenediamine) tri-μ-oxido-oxidocopper(II)molybdenum(VI)]
(International Union of Crystallography, 2008)
A new organic–inorganic two-dimensional hybrid compound, [CuMoO4(C2H8N2)], has been hydrothermally synthesized at 443 K. The unit cell contains layers composed of CuN2O4 octahedra and MoO4 tetrahedra. Corner-sharing MoO4 ...
Rhodium-catalyzed carbonylative arylation of alkynes with arylboronic acids: An efficient and straightforward method in the synthesis of 5-aryl-2(5H)-furanones
(Royal Society of Chemistry, 2006)
5-Aryl-2(5H)-furanones can be synthesized by the Rh-catalyzed reactions of arylboronic acids with internal alkynes under a CO atmosphere.
Speciation and preconcentration of inorganic tellurium from waters using a mercaptosilica microcolumn and determination by hydride generation atomic absorption spectrometry
(Royal Society of Chemistry, 2000-11-23)
A separation–preconcentration method utilising a mercapto-modified silica microcolumn was developed for the determination of trace amounts of Te(IV) and Te(VI) in waters by hydride generation atomic absorption spectrometry. ...
Optical transition rates of a meso-substituted thiacarbocyanine in methanol-in-oil reverse micelles
We report the photophysical properties of 3,3′-diethyl-5,5′-dichloro-9-phenylthiacarbocyanine (DDPT) in methanol-in-oil (m/o) reverse micellar systems which form methanol droplets stabilized with anionic surfactant aerosol-OT ...
NMR studies on natural and synthetic Amavadin
The stereochemistry of isolated natural product Amavadin, which contains a 1:2 complex of V(IV) with N-hydroxyimino-2,2′-dipropionic acid (HIDPAH3), and some synthetic complexes have been investigated. Amavadin was isolated ...
