Cobalt supported chitosan-derived carbon-smectite composite for catalytic activation of peroxymonosulfate in water
(Society of Physical Chemists of Serbia, 2021)
In this work cobalt supported on chitosan-derived carbon-smectite composite catalyst was synthetized using impregnation-carbonization method (Co/cCh-S). The carbonization temperature was 400 °C. The obtained catalyst was ...
Kinetic and thermodynamic study of nicotine degradation by oxone® activated by cobalt based catalyst
(Society of Physical Chemists of Serbia, 2022)
Acid activated montmorillonite was impregnated with Co2+ ions, calcined at 450 , and used as
catalyst for Oxone® activation in catalytic oxidative degradation of nicotine. Catalytic tests were
performed in temperature ...
The Briggs-Rauscher oscillatory reaction method as a “fingerprint” for bentonite clays
(Serbian Ceramic Society, 2022)
The oscillatory Briggs-Rauscher (BR) reaction was applied on solid insoluble materials -
bentonite clays from different deposits: Wyoming (Swy-2), Texas (STx-1b), Idaho (SbId-1),
Arizona (SAz-2), Bogovina and Mečji Do, ...
Application of mechanochemically activated sodium carbonate in environmental protection
(University of Belgrade, Technical faculty in Bor, 2021)
Sodium carbonate samples were mechanically activated in a vibro mill. The increase in the free surface area of the activated samples was monitored by the BET method and the state of the crystal lattice by the diffraction ...
Manufacture and characteristics of shape memory alloys for electronic purposes
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
Among the variety of advanced materials with exceptional properties and applications, shape
memory alloys (SMAs) have a unique ability to return to previously defined shapes or sizes if subjected to the relevant thermal ...
Neat and loaded CaO-based catalysts from natural or waste sources for the triacylglycerols methanolysisis reaction
(Serbian Ceramic Society, 2022)
In recent decades, especially in recent years, more and more attention is focused on energy
consumption, energy efficiency, fossil fuels emission and depletion, and alternative energy
sources and uses. Biofuels, such ...
An Unusual Behavior of the Briggs-Rauscher Oscillatory Reaction with Addition of Bentonite Clays
(Belgrade : Serbian Ceramic Society, 2021)
The Briggs-Rauscher (BR) reaction is visually the most interesting oscillating reaction, in which the oxidation of malonic acid by a mixture of hydrogen peroxide and iodate is catalyzed by Mn2+metal ion in acidic solution. ...
Removal efficiency of pb(II), Zn(II) and Cu(II) in mono- and multimetal systems by alkali treated apricot shells biosorbent
(Society of Physical Chemists of Serbia, 2022)
The mutual interaction of metal ions (lead, zinc and copper) on removal efficiency in binary and
ternary systems, by biosorbent based on alkali treated apricot shells (Prunus armeniaca L.) was
examined. The evaluation ...
Development and validation of HPTLC method for determination of sugar profiles of honey and its syrup adulterants
(Croatian Chemical Society, 2021)
Honey is a natural sweet product of honeybees widely consumed by people as both a food and
a medicine. It is mainly composed of carbohydrates, primarily fructose and glucose, followed by
sucrose and other oligosaccharides ...
Electrochemical investigation of 2-thiohydantoin derivatives as corrosion inhibitors for mild steel in acidic medium
(Institute for Information Technologies, University of Kragujevac, Serbia, 2021)
Four 2-thiohydantoin derivatives were synthesized and their corrosion inhibition properties on mild
steel (MS) in 0.5M HCl solution was evaluated using usual gravimetric and electrochemical methods (weight loss, potentiodynamic ...
