Functionalized macroporous copolymer of glycidyl methacrylate: The type of ligand and porosity parameters influence on Cu(II) ion sorption from aqueous solutions / Funkcionalizovani makroporozni kopolimer na bazi glicidilmetakrilata - uticaj liganda i parametara poroznosti na sorpciju Cu(II) jona iz vodenih rastvora
(Association of Chemical Engineers of Serbia, 2009)
The removal of heavy metals from hydro-metallurgical and other industries' wastewaters, their safe storage and possible recovery from waste- water streams is one of the greater ecological problems of modern society. ...
Ethylene oxide removal by sorption on aluminium oxide / Uklanjanje etilen oksida sorpcijom na aluminijum oksidu
(Association of Chemical Engineers of Serbia, 2009)
The dynamics of ethylene oxide sorption and desorption on Al2O3 sorbent were investigated. The investigations of ethylene oxide sorption on Al2O3 show that significant sorption appeared above 125°C. The removal of sorbed ...
Planar chromatography of cholic acid-derived cis-trans isomeric bis-steroidal tetraoxanes
(Journal of Planar Chromatography - Modern TLC, 2009)
Seven pairs of cis-trans isomers of bis-steroidal tetraoxanes have been examined by both normal-phase (NP) and reversed-phase (RP) planar chromatography. Unmodified silica gel was used with ethyl acetate-toluene and ethyl ...
The state of nickel in the silver modified NiMg/SiO2 vegetable oil hydrogenation catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Two series of silver modified Ni-Mg materials were synthesized by precipitation-deposition on SiO2 support derived from two silica sources: diatomite activated at 800°C (Series a; Mg/Ni = 0.1 and SiO 2/Ni = 1.07) and ...
Fishnet-Based Metamaterials: Spectral Tuning Through Adsorption Mechanism
(Polish Academy of Sciences, 2009)
In this work we consider the tuning of spectral reflectance of fishnet metamaterials with circular or elliptic apertures due to the presence of dielectric analyte adsorbed within the pores of the dielectric part. We simulated ...
Crystal structure of 2-{1-[(1-(2-pyridinio)ethylidene)hydrazono]ethyl} pyridinium diperchlorate, the product of template condensation in the presence of Cr(III)
(Journal of Chemical Crystallography, 2009)
In an attempt to synthesize a Cr(III) complex of 2′-[1-(2-pyridinyl) ethylidene]oxamohydrazide an azine product 2-{1-[(1-(2-pyridinio)ethylidene) hydrazono]ethyl}pyridinium diperchlorate was obtained by an electrophilic ...
Characterization of volatile compounds of "Drenja", an alcoholic beverage obtained from the fruits of cornelian cherry / Karakterizacija isparljivih komponenti 'Drenje', alkoholnog pića dobijenog iz plodova drenjine (Cornus mas)
(Serbian Chemical Soc, Belgrade, 2009)
In this study, volatile compounds were analyzed in five samples of home-made spirit beverage made by the distillation of fermented fruits of cornelian cherry (Cornus mas L.). The major volatile compounds, besides ethanol, ...
