Kinetic and Isotherm Non-Linear Study of Cr(VI) Sorption onto Amino-Modified Macroporous GMA Based Copolymer
(Skopje : Society of chemists and technologists of Macedonia, 2023)
Hexavalent chromium, Cr(VI), is one of the most notorious pollutants with
health and environmental impacts due to carcinogenic, teratogenic, and mutagenic
effects on the human organism.1 Therefore, treating wastewater ...
Pulverized river shellfish shells as a cheap adsorbent for removing of malathion from water: Examination of the isotherms, kinetics, thermodynamics and optimization of the experimental conditions by the response surface method
(University of Defence in Belgrade, 2021)
Introduction/purpose: In this study, we investigated the possibility of removing the organophosphorus pesticide malathion from water using a new adsorbent based on the biowaste of river shell shards from the Anodonta ...
Leaching of copper(I) sulphide by sulphuric acid solution with addition of sodium nitrate
(Elsevier, Amsterdam, 2003)
Finely grained samples of copper(I) sulphide were leached by H2SO4 solution with added NaNO3. The occurrence probability of chemical reactions was analysed based on literature data and products which were formed during the ...
Hydrogen evolution reaction from EDTA solutions
(4th Conference of the Yugoslav Materials Research Society, 2002)
An attempt was made to investigate the mechanism and kinetics of hydrogen evolution reaction on zinc and platinum wire electrodes from solutions containing ethylene diamine tetraacetic acid (EDTA). EDTA is a tetra-basic ...
Kinetics and sintering mechanisms of hydro-thermally obtained hydroxyapatite
(Elsevier, 2008)
In this paper, the kinetics and sintering mechanism of hydro-thermally synthesized hydroxyapatite in the temperature range 900-1100 degrees C are presented. It was found that at 900 degrees C, the sintering process is very ...
Catalytic incineration of ethylene oxide in the packed bed reactor
(Elsevier, 2006)
Investigations of catalytic incineration of ethylene oxide (ETO) over Pt/Al2O3 catalyst have been conducted on laboratory and pilot scale level. The measurements of the reaction rate conducted under gradientless conditions ...
The kinetics of the hydrogen evolution reaction on zinc in EDTA solutions in the pH 3-10 range
(Elsevier Science Sa, Lausanne, 2003)
Polarization curves of the hydrogen evolution reaction on zinc were obtained in Ethylenediaminetetraacetic acid (EDTA) solutions of different total molar concentrations (0.05, 0.10, 0.15 and 0.20 mol dm(-3)), the pH values ...
The Extraction of Copper from Chalcopyrite Concentrate with Hydrogen Peroxide in Sulfuric Acid Solution
(MDPI, 2023)
Research on chalcopyrite leaching represents a great challenge, given its importance as one of the most abundant copper minerals and its significant role in global copper extraction. This study aimed to evaluate the effects ...
Removal of lindane from aqueous solution by glycidyl methacrylate based chelating macroporous copolymer: kinetics and mechanism
(Banja Luka : University in Banjaluka, Faculty of Technology, 2023)
Lindane belongs to the persistent organic pollutants (POPs) group, which can cause carcinogenic,
endocrine, and neurological problems in an organism. The widespread presence of lindane in the
environment demands efficient ...
