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 ...
Ispitivanje adsorpcionih svojstava ilovače za uklanjanje jona olova i arsena iz vodenih rastvora
(Akademija tehničkih strukovnih studija Beograd, 2021)
Olovo i arsen predstavljaju značajnu grupu neorganskih polutanata koji su prisutni u
životnoj sredini, pre svega u vodenim sistemima, pa je njihovo uklanjanje veliki tehničkotehnološki izazov. Zbog toga se sve više pažnje ...
Structural Characteristics and Adsorption Properties of Alkali Activated Blends Ashes/Metakaolin
(Skopje : Society of Chemists and Technologists of Macedonia, 2023)
The aim of this paper is to show the possibility of using waste materials, blends of (wood ash, fly ash, from thermal power plant, and metakaolin) for the production of alkali activated materials that can be used to purify ...
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 ...
Sawdust based hydtrothermal carbon as adsorbent for removal of sterols from water
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2020)
Nowadays, various types of inexpensive, sustainable and renewable lignocellulosic waste materials are
increasingly being utilized as precursors for carbon adsorbents production. The usage of the lignocellulosic
wastes ...
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 ...
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 ...
Screening for factors affecting cellulose adsorption from solutions by modified coffee residues
(International Conference on Civil, Biological and Environmental Engineering (CBEE-2014), 2014)
In the present study, the modified coffee residues were used as low cost adsorbent for immobilization of cellulase enzyme. In the batch model for adsorption, the experimental parameters: the temperature, the initial cellulase ...
BIOSORBENTI ZA PREČIŠĆAVANJE OTPADNIH VODA IZ TEKSTILNE INDUSTRIJE / TEXTILE INDUSTRY WASTE WATERTREATMENT
(Beograd : Beogradska politehnika, 2019)
Jedna od najaktuelnijih tema u svetu je ekologija i zagađenje
životne sredine. Ispuštanje toksičnih materija iz raznih industrijskih
pogona u neposrednu okolinu dovodi do zagađenja vode, vazduha i zemljišta.
U pogonima ...
