Hydro- and solvothermally-prepared ZnO and its catalytic effect on the photodegradation of Reactive Orange 16 dye
(Srpsko hemijsko društvo, Beograd, 2014)
In this work, zinc oxide powders were obtained by two different techniques: hydro- and solvothermal synthesis starting from Zn(NO3)(2) and Zn(CH3COO)(2), respectively. The influence of synthetic procedure on the structural, ...
Modification of natural clinoptilolite for nitrate removal from aqueous media
(Srpsko hemijsko društvo, Beograd, 2014)
Natural zeolitic tuff from the Zlatokop mine (Vranjska Banja deposit, Serbia) was investigated as the starting material to obtain a low cost adsorbent for the removal of nitrate from aqueous media. The tuff rich in zeolite, ...
Optimization of electrochemical decolorization of certain arylazo pyridone dyes
(Srpsko hemijsko društvo, Beograd, 2014)
Electrocatalytic decolorization of arylazo pyridone dyes was investigated in the presence of sodium chloride using a DSA Ti/PtOx electrode in dilute sodium hydroxide. The decolorization could be attributed to the indirect ...
Modeling of density and calculations of derived volumetric properties for n-hexane, toluene and dichloromethane at pressures 0.1-60 MPa and temperatures 288.15-413.15 K
(Srpsko hemijsko društvo, Beograd, 2015)
Densities data of n-hexane, toluene and dichloromethane at temperatures 288.15-413.15 K and at pressures 0.1-60 MPa, determined in a previous article, were fitted to the modified Tait equation of state. The fitted ...
Densities, refractive indices and viscosities of the binary mixtures of dimethyl phthalate or dimethyl adipate with tetrahydrofuran
(Srpsko hemijsko društvo, Beograd, 2014)
Densities, refractive indices and viscosities of the binary mixtures of dimethyl phthalate (or dimethyl adipate) + tetrahydrofuran have been measured at eight temperatures (288.15 to 323.15 K) and atmospheric pressure. All ...
Prediction of excess molar volumes of selected binary mixtures from refractive index data
(Srpsko hemijsko društvo, Beograd, 2014)
The excess molar volumes of twenty two binary mixtures containing various groups of organic compounds: alcohols (ethanol, 1-propanol, 1,2-propanediol, 1,3-propanediol and glycerol), ketone (acetone), ester (butyl lactate), ...
Liquid mixture viscosities correlation with rational models
(Srpsko hemijsko društvo, Beograd, 2014)
In this paper, twenty two selected rational correlation models for the viscosities of liquid mixtures of organic compounds were tested on 219 binary sets of experimental data taken from the literature. The binary sets ...
Adsorption of Candida rugosa lipase onto alumina: effect of surface charge
(Serbian Chemical Society, 2015)
The impact of the surface charge of alumina supports on the adsorption of Candida rugosa lipase was investigated in terms of the zeta potentials of the adsorption partners. The lipase adhered onto alumina with similar ...
A microwave approach to the synthesis of certain 4-(substituted phenyl)-6-phenyl-3-cyano-2-pyridones
(Srpsko hemijsko društvo, Beograd, 2014)
A study of the synthesis of 4-(substituted phenyl)-6-phenyl-3-cyano-2-pyridones from ethyl 2-cyano-3-(substituted phenyl) acrylates and acetophenone is presented. The 2-pyridones were obtained using conventional as well ...
Structural, spectral and thermal properties of 2-(2-pyridylamino)pyridinium trihydrogen pyromellitate / Структурна, спектрална и термичка својства 2-(2-пиридиламино)пиридиниjум-трихидрогенпиромелитата
(Srpsko hemijsko društvo, 2014)
The title compound, (Hdipya)(H(3)pyr), where Hdipya is protonated 2,2'-dipyridilamine and H(3)pyr is the monoanion of pyromellitic acid (H(4)pyr), was obtained from a reaction mixture containing Zn(II) ions, dipya, Na(4)pyr ...
