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 ...
Isotherm, Thermodynamic and Kinetic Studies of Elemental Sulfur Removal from Mineral Insulating Oils Using Highly Selective Adsorbent
(MDPI, 2023)
Elemental sulfur (S8) is a corrosive sulfur compound which was found to be extremely reactive to silver, causing intensive silver sulfide (Ag2S) deposition on on-load tap changer (OLTC) contacts in power transformers. A ...
Plant waste materials from restaurants as the adsorbents for dyes / Iskorišćenje sirovog otpada iz restorana za adsorpciju boja
(Association of Chemical Engineers of Serbia, 2015)
This paper has demonstrated the valorization of inexpensive and readily available restaurant waste containing most consumed food and beverage residues as adsorbents for methylene blue dye. Coffee, tea, lettuce and citrus ...
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 ...
Adsorption of Metformin on Activated Carbon Produced from the Water Hyacinth Biowaste Using H3PO4 as a Chemical Activator
(MDPI, 2022)
Water hyacinth biomass was used for the synthesis of activated carbons in the process of chemical activation with H3PO4, followed by controlled carbonization. The study investigates the effect of various impregnation weight ...
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 ...
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 ...
The thermal stability of poly(sec-butyl methacrylate) / Termička stabilnost poli(sec-butil metakrilata)
(Društvo inženjera plastičara i gumara, Beograd, 2000)
The thermal stability of a series of poly(sec-butyl methacrylate)(PsBMA) samples was investigated by non-isothermal thermogravimetry (TG). The PsBMA samples were synthesised by bulk radical polymerization in the presence ...
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) ...
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 ...
