Activated carbon materials derived from hemp fibers in pesticide adsorption and water disinfection / Adsorpcija pesticida i dezinfekcija vode aktiviranim ugljeničnim materijalima na bazi vlakana konoplje
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2015)
By varying the parameters of carbonization and activation, different samples of hemp fibers based activated carbon were obtained. Optimal production conditions were selected based on the adsorption properties of activated ...
Hemp (Cannabis sativa) fibers as biosorbents and precursor for carbon sorbent production / Vlakna konoplje (Cannabis sativa) kao biosorbenti i sirovine za proizvodnju ugljeničnih sorbenata
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2015)
Short and entangled hemp fibers, obtained as a waste from textile industry, were used as efficient biosorbent and low-cost precursor for carbon sorbent production. In order to obtain the biosorbents with better sorption ...
Arsenic(III) adsorption from aqueous solutions on novel carbon cryogel/ceria nanocomposite
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2016)
Carbon cryogel/ceria composite, with 10 wt.% of ceria, was synthesized by mixing of ceria and carbon cryogel (CC). The sample was characterized by field emission scanning electron microscopy, nitrogen adsorption and X-ray ...
Separation and determination of dimethylarsenate in natural waters / Razdvajanje i određivanje dimetilarsenata u prirodnim vodama
(Serbian Chemical Society, Belgrade, 2012)
A simple and efficient method for the separation and determination of dimethylarsenate DMAs(V) was developed in this work. Two resins, a strong base anion exchange (SBAE) resin and iron-oxide coated hybrid (HY) resin were ...
Removal of a cationic dye from water by activated pinecones
(Srpsko hemijsko društvo, Beograd, 2012)
Adsorption of a cationic phenothyazine dye, Methylene Blue onto activated carbon prepared from pinecones was investigated. The parameters contact time, dye concentration and pH were varied. The kinetic data were found to ...
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 ...
Applicability of zeolites in potassium and nitrate retention in different soil types
(Srpsko hemijsko društvo, Beograd, 2017)
Environmental protection and sustainable agricultural production require the use of inexpensive and environmentally acceptable soil supplements. Objectives of this study were to investigate the influence of the addition ...
Oxidized and Ethylenediamine-Functionalized Multi-Walled Carbon Nanotubes for the Separation of Low Concentration Arsenate from Water
(Taylor & Francis Inc, Philadelphia, 2013)
In this work multiwalled carbon nanotubes (MWCNTs) modified by oxidation (o-MWCNTs) and by aminofunctionalization (e-MWCNTs) were examined as potential adsorbents for arsenate removal from water. Adsorption characteristics ...
A comparative study of the removal of lead, cadmium and zinc ions from aqueous solutions by natural and Fe(III)-modified zeolite / Uporedna analiza uklanjanja jona olova, kadmijuma i cinka iz vodenih rastvora adsorpcijom na prirodnom i Fe(III)- modifikovanom zeolitu
(Association of the Chemical Engineers of Serbia, 2014)
The main purpose of this research was to explain the differences in the adsorption mechanisms and adsorption capacities of natural and Fe(III)-modified zeolite for Pb2+, Zn2+ and Cd2+. The adsorbents were characterized ...
Fluoride ion adsorption onto Al-alginate particles / Adsorpcija fluoridnih jona na Al-alginatnim česticama
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
Fluoride ions are increasingly present in the groundwater mainly due to the anthropogenic activity. On the other hand, increased awareness of harmful effects caused by high concentrations of F-in drinking water, leads to ...
