Nonlinear FR-ZLC method for investigation of adsorption equilibrium and kinetics
(Springer, New York, 2008)
A new method for investigation of adsorption equilibrium and kinetics, named Nonlinear Frequency Response-Zero Length Column (NFR-ZLC) method, is introduced. It combines the advantages of the Nonlinear FR method (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, ...
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 ...
The thermal degradation kinetics of dextran and pullulan
(John Wiley & Sons Ltd, W Sussex, 1993)
The effect of molar mass and, in the case of dextran, of the degree of branching on the thermal degradation kinetics of dextran and pullulan was studied in the presence and absence of oxygen. Although the initial mass loss ...
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, ...
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 ...
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) ...
Factors influencing the removal of divalent cations by hydroxyapatite
(Elsevier, Amsterdam, 2008)
The effect of pH, contact time, initial metal concentration and presence of common competing cations, on hydroxyapatite (HAP) sorption properties towards Ph2+, Cd2+, Zn2+, and Sr2+ ions was studied and compared using a ...
