Adsorptive Removal of Technetium-99 Using Macroporous Poly(GMA-co-EGDMA) Modified with Diethylene Triamine
(Wiley-Blackwell, Malden, 2012)
dThe possibility of sorption of technetium-99 in the form of pertechnetate anion (TcO(4)(-)) and the sorption kinetics for removing TcO(4)(-) from aqueous solution by chelating polymers based on glycidyl methacrylate (GMA) ...
The application of zeolite nanopowder for the construction of the dense composite polymer membranes for carbon dioxide separation
(Inst Materials Physics, Bucharest, 2012)
The main task of the work is to construct the polymeric membrane that could be used for the waste gases treatment. For this purpose, membrane must have high permeability for the carbon dioxide and low permeability of the ...
Diffusion and solubility of commercial poly(methyl methacrylate) denture base material modified with dimethyl itaconate and di-n-butyl itaconate during water absorption/desorption cycles
(Wiley-Blackwell, Hoboken, 2012)
This study evaluated the water absorption, solubility, kinetics of water diffusion and residual monomer content of commercial poly(methyl methacrylate) (PMMA) denture base material modified with dimethyl itaconate (DMI) ...
Pharmaceutical residues in the Danube River Basin in Serbia - a two-year survey
(Iwa Publishing, London, 2012)
Pharmaceuticals are emerging contaminants with damaging effects to the environment and human health. Their presence in surface and especially groundwaters is regarded as detrimental, as they can ultimately reach drinking ...
Methods for monitoring of pesticide residues in water: current status and recent trends
(Iwa Publishing, London, 2012)
An overview of analytical methods currently used for the determination of pesticide residues in water samples is presented. As liquid chromatography and gas chromatography, coupled to mass spectrometry, are considered to ...
Specificity of maltase to maltose in three different directions of reaction: Hydrolytic, vanillyl alcohol glucoside and vanillyl alcohol isomaltoside synthesis
(Wiley, Hoboken, 2012)
Vanillyl alcohol glucoside is very attractive molecule due to its very powerful physiological activity. In this article, a detailed kinetic study of transglucosylation of vanillyl alcohol was performed. It was demonstrated ...
Production and ionization energies of KnF (n=2-6) clusters by thermal ionization mass spectrometry
(Wiley, Hoboken, 2012)
RATIONALE The very small clusters of the type KnF are of particular importance since their first ionization energies (IEs) are lower than those of the alkali metal atoms. Theoretical calculation has demonstrated that this ...
Electrochemically deposited nano fibrous polyanilne for amperometric determination of glucose
(Inst Materials Physics, Bucharest, 2012)
Electrochemical deposition of polyaniline (PANI) on graphite electrode was performed galvanostaticaly at constant current density in the range of 1.0 - 5.0 mA cm(-2) from aqueous acidic electrolyte containing aniline ...
Health risks of heavy metals in the mediterranean mussels as seafood
(Springer-Verlag, 2012)
In recent years, mussels have already become commercially important seafood species worldwide. Mussels accumulate a wide range of metals in their soft tissue. Thus, the determination of accumulated concentrations of heavy ...
