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 ...
Kinetic properties of the Ti-Ni intermetallic phases and alloys for hydrogen evolution
(Elsevier Science Sa, Lausanne, 1997)
The kinetics and mechanism of hydrogen evolution at Ti-Ni alloy electrodes prepared by are-melting and mechanical alloying methods has been studied by means of AC impedance spectrum measurements. The electrode, prepared ...
Radical polymerization of monoethyl itaconate / Radikalna polimerizacija monoetil itakonata
(Association of Chemical Engineers of Serbia, 2003)
The radical polymerization of monoethyl itaconate (MEI) was investigated in bulk and in solution at 60°C using a,a'-azobisisobutyronitrile as initiator. It was established that the obtained polymer poly(monoethyl itaconate) ...
The non-oxidative thermal degradation of poly (Di-2-chloroethyl itaconate)
(John Wiley & Sons Ltd, W Sussex, 1993)
The non-oxidative thermal degradation of poly (di-2-chloroethyl itaconate) (PD2CEI) was studied by TG and by analysing the thermal products. The major processes occurring during thermal analysis are crosslinking, ...
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, ...
Removal of copper(II) ion from aqueous solution by high-porosity activated carbon
(Water Research Commission, Pretoria, 2013)
The removal of copper(II) ion from aqueous solution by the granular activated carbon, obtained from hazelnut shells (ACHS) (Corylus avellana L. var. lunga istriana), was investigated. The ACHS was prepared from ground dried ...

This work presents the laboratory testing results of kinetics the oxidation process and sample processing of the sulphide polymetallic concentrate Blagojev Kamen. The aim of investigation is recovery of these types of raw ...
The mechanism and kinetics of the tungsten (vi)-oxide reduction in the vertical tube reactor
(Editura Stiintifica Fmr, Bucharest, 2012)
Presented study shows the analysis of the process of reduction of WO 3 powder with hydrogen in the vertical tube reactor, representing a new approach in comparison to the conventional methods in the horizontal tube reactor. ...
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 ...
Methacrylate-Based Polymeric Sorbents for Recovery of Metals from Aqueous Solutions
(MDPI, 2022)
The industrialization and urbanization expansion have increased the demand for precious and rare earth elements (REEs). In addition, environmental concerns regarding the toxic effects of heavy metals on living organisms ...
