Eco-chemical status of the Korbevacka River in souht-eastern Serbia
(Parlar Scientific Publications (P S P), Freising, 2007)
The Korbevacka River is located in the south-eastern part of Serbia. This river is a main recipient of all kinds of pollutants from the local Pb-Zn mine "Grot". Determination of the eco-chemical status comprised complete ...
Transition metal complexes with thiosemicarbazide-based ligands. part 37. Synthesis and study of the first thiosemi-carbazide-derived copper(I) complexes: Crystal structure of [2-(diphenylphosphino)benzaldehyde thiosemicarbazonato(-l)] copper(I)nitrate-me
(Taylor & Francis Ltd, Abingdon, 2000)
The preparation and physical characterization of two copper(I) complexes Cu(HL)NO3 and [Cu(HL)(2)]NO3 . MeOH formed with a newly synthesized tridentate [S,N,P] HL = 2-(diphenylphosphino)benzaldehyde thiosemicarbazone ligand ...
Quantitative Structure-Retention Relationships of Mixed Tris-beta-Diketonato Complexes on Polyacrylonitrile Sorbent
(Vieweg, Wiesbaden, 2008)
Quantitative structure-retention relationships models have been developed for thin-layer chromatographic parameters of 30 mixed beta-diketonato complexes. In order to obtain predictive and interpretative models, we ...
A modification of the kinetic determination of pancuronium bromide based on its inhibitory effect on cholinesterase
(Wiley-Liss, Hoboken, 2007)
A modification of the existing spectrophotometric kinetic method for the determination of pancuronium bromide (PCBr), based on pooled human serum cholinesterase (ChE, EC 3.1.1.8 acylcholine acylhydrolase) inhibition, was ...
Preparation of combined extract of cell wall and cytosol antigens of Candida albicans for immunoblot analysis
(Wiley-Liss, Hoboken, 2007)
Immunoblot analysis is not in wide use for diagnosis of invasive candidiasis, mostly because the procedure is not standardized and hence not reliable. This work describes a standardized method for C. albicans antigen extract ...
NaY zeolite: A useful catalyst for nitrile hydrolysis
(Molecular Diversity Preservation International, Basel, 2000)
The NaY zeolite catalysed hydrolysis of nitriles to primary amides is reported. It is found that aryl nitriles with strong electron-withdrawing substituents and cyanopyridines are readily hydrolysed in the water suspension, ...
Screening of selenium absorption ability of mycelia of selected Pleurotus species
(Teknoscienze Publ, Milan, 2006)
Pleurotus species are economically high praised due to their edible and medicinal properties. Selenium is a trace element with antioxidant and anticarcinogenic effects. The aim of our research was to investigate the influence ...
Use of different salt solutions in salting-out TLC of Co(III) complexes on silica gel
(Vieweg, Wiesbaden, 2008)
Saturated aqueous solutions of 28 different salts have been studied as a potential mobile phases for salting-out thin-layer chromatography, on silica gel, of a series of four mixed bis-aminocarboxylato cobalt(III) complexes. ...
Improved procedure for the preparation of cis-2,4-dimethylglutaranhydride
(Taylor & Francis Inc, Philadelphia, 2006)
Addition of 2.5 mol% DBU to a mixture of isomeric 2,4-dimethylglutaric anhydrides in ethyl acetate promotes crystallization-induced transformation, affording the pure cis-2,4-dimethylglutaric anhydride in 87% yield.
Kinetics of Cu2+ binding to the poly(acrylic acid) hydrogel
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Isothermal kinetics of copper (ion) binding to poly(acrylic acid) (PAA) hydrogel at 20, 25, 35 and 45 C was investigated. Isothermal conversions and kinetic curves of Cu2+ binding to the PAA hydrogel were determined. It ...
