Dissolution behavior of a polyphosphate glass in simulated body fluid
(Srpsko hemijsko društvo, Beograd, 2017)
In this work, the dissolution behavior of a polyphosphate glass, with the composition 45P(2)O(5) center dot 3SiO(2) center dot 25K(2)O center dot 15CaO center dot 10MgO center dot ZnO center dot MnO (mol %), in simulated ...
Kinetics of heterogeneous methanolysis of sunflower oil with CaO·ZnO catalyst: Influence of different hydrodynamic conditions / Kinetika heterogene metanolize suncokretovog ulja sa CaO·ZnO kao katalizatorom - uticaj različitih hidrodinamičkih uslova
(Association of the Chemical Engineers of Serbia, 2014)
The kinetics of heterogeneous methanolysis of sunflower oil was studied at 60 °C using mechanochemically synthesized CaO·ZnO as catalyst. The influence of agitation speed, catalyst amount, and methanol-to-oil molar ratio ...
Biodiesel synthesis and kinetic analysis based on MnCO3/Na silicate as heterogeneous catalyst
(Srpsko hemijsko društvo, Beograd, 2018)
The MnCO3/Na silicate (Mn/Na/Si mole ratio of 4.65:1:1.65) catalyst in the form of solid particles with diameter of 0.99-1.99 mm was used as a catalyst for transesterification of soybean oil in batch autoclave at different ...
The effect of K2O on the crystallization of niobium germanate glasses
(International Institute for the Science of Sintering, Beograd, 2011)
The effect of K2O content on the crystallization of niobium germanate glasses with 22.7- 24.27 wt% of GeO2 and 54.59-57.48 wt% of Nb2O5 was examined. The glasses crystallize by primary crystallization and the formed ...
Lead(ii) removal from aqueous solutions by Serbian zeolitic tuff
(Gheorghe Asachi Technical University of Iasi, Romania, 2017)
The present study was aimed at examining the ability of the natural zeolitic tuff from the Zlatokop deposit in Serbia to remove Pb(II) ions from aqueous solutions under various conditions. It has been found that the ...
Crystal growth of K2TiGe3O9 in the glass / Rast kristala K2TiGe3O9 u staklu
(Serbian Chemical Society, Belgrade, 2010)
The kinetics and mechanism of isothermal crystal growth of K2TiGe3O9 from a glass of the same stoichiometric composition were studied. The crystal growth rate, U, in the range 1x10-11-1.27x10-10 m s-1 was experimentally ...
Sorption of Cu2+ and Co2+ from aqueous solutions onto sepiolite: An equilibrium, kinetic and thermodynamic study / Sorpcija jona bakra i kobalta iz vodenih rastvora na sepiolitu, ispitivanje ravnoteže, kinetike i termodinamike sorpcije
(Serbian Chemical Society, Belgrade, 2011)
The efficiency of natural sepiolite for the removal of Cu2+ and Co2+ from aqueous solution was determined using the batch method. The sorption experiments were performed as a function of the initial metal concentration, ...
The thermal degradation kinetics of poly(chlorethylmethacrylates)
(John Wiley & Sons Ltd, W Sussex, 1992)
The thermal degradation kinetics of poly(2-mono-, 2,2-di- and 2,2,2-trichlorethyl methacrylate) and of the non-chlorinated poly(ethyl methacrylate) were studied by TG in the absence and presence of oxygen. The overall ...
Kinetics of the zinc anodic dissolution reaction in near neutral EDTA solutions / Kinetika anodnog rastvaranja cinka u blisko neutralnim rastvorima EDTA
(Serbian Chemical Society, Belgrade, 2003)
Polarization curves of the anodic dissolution reaction of zinc were determined in EDTA solutions of different total molar concentrations (0.05 0.10, 0.15 and 0.20 mol dm-3), the pH values of which were systematically varied ...
