Efficient pollutants removal by amino-modified nanocellulose impregnated with iron oxide
(Srpsko hemijsko društvo, Beograd, 2016)
A novel adsorbent, NC-PEG, obtained by modification of nanocellulose (NC) with PEG-6-arm amino polyethylene glycol (PEG-NH2) via maleic anhydride (MA) linker, was used for removal of Cd2+ and Ni2+ from water. A subsequent ...
Waste Cotton and Cotton/Polyester Yarns as Adsorbents for Removal of Lead and Chromium from Wastewater
(Journal of Natural Fibers, 2022)
The possibility of using waste cotton and cotton/polyester yarns to remove lead and chromium ions from polluted water was investigated in this work. Structural, morphological, and adsorption properties of yarns were ...
The Application of a Natural Zeolite for Acid Mine Drainage Purification
(Japan Inst Metals & Materials, Sendai, 2015)
A natural zeolite from Serbia was employed for the removal of heavy metals from acid mine drainage (AMD) generated in the area of copper mine. The efficiency of the natural zeolite samples was tested on AMD that contained ...
Bisphenol a removal from aqueous solution using fine alpha-fe2o3 particles
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Iron(III) oxide particles (alpha-Fe2O3) were obtained from ferrous chloride (FeCl3 center dot 6H(2)O) precursor using ammonium hydroxide as a precipitating agent and particles were calcined at 700 degrees C for 4 h. ...
Speciation of Hexavalent Chromium in Aqueous Solutions Using a Magnetic Silica-Coated Amino-Modified Glycidyl Methacrylate Polymer Nanocomposite
(MDPI, 2023)
A new magnetic amino-functionalized polymeric sorbent based on glycidyl methacrylate was synthesized and used in the separation of chromium Cr(VI) oxyanions sorption from aqueous solutions in a static batch system. The ...
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 ...
Adsorptive pretreatment of waste cooking oil using quicklime for fatty acid methyl esters synthesis
(Association of the Chemical Engineers of Serbia, 2023)
Synthesis of biodiesel from various plant oils is realized by the transesterification of triglycerides with methanol or by a reaction usually defined as methanolysis. The usage of low-quality oils, such as waste cooking ...
Use of Natural Clinoptilolite in the Preparation of an Efficient Adsorbent for Ciprofloxacin Removal from Aqueous Media
(Minerals, 2021)
The adsorption of the antibiotic ciprofloxacin (CIP) from an aqueous solution by natural zeolite, the calcium-rich clinoptilolite (CLI), and magnetite-coated CLI (MAG-CLI) was investigated. Both CLI and MAG-CLI showed a ...
Lignin Microspheres Modified with Magnetite Nanoparticles as a Selenate Highly Porous Adsorbent
(MDPI, 2022)
Highly porous lignin-based microspheres, modified by magnetite nanoparticles, were used for the first time for the removal of selenate anions, Se(VI), from spiked and real water samples. The influence of experimental ...
Advances in the Applications of Clinoptilolite-Rich Tuffs
(MDPI, 2024)
Adsorptive, catalytic, and antibacterial properties of clinoptilolite-rich tuffs (ZT) are presented here. ZT transformed into Fe-containing ZT (Fe-ZT) removes various organic and inorganic anions from water. Fe-ZT, which ...
