Surfactant modification and adsorption properties of clinoptilolite for the removal of pertechnetate from aqueous solutions
(Springer, Dordrecht, 2016)
Natural clinoptilolite modified with a cationic surfactant stearyldimethylbenzylammonium chloride (SDBAC) was used as an adsorbent for the removal of pertechnetate from aqueous solutions. Adsorption studies were performed ...
Značaj valorizacije i načini prerade sekundarnih sirovina obojenih metala / The valorization impact and methods for treatment of non ferrous secondary raw materials
(Savez inženjera i tehničara Srbije, Beograd, 2017)
Proizvodnja obojenih metala iz sekundarnih sirovina daleko je jeftinija od njihove proizvodnje iz primarnih sirovina, prvenstveno zbog manje potrošnje energije. Pored toga, reciklažom obojenih metala iz sekundarnih sirovina ...
Dissolution of copper from smelting slag by leaching in chloride media
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2017)
Leaching of copper smelting slag in chloride media was studied. The lixiviants used were aqueous solutions of hydrochloric acid (0.5-2.0 M HCl) as well as hydrogen peroxide and hydrochloric acid (0.5-3.0 M H2O2, 1.0 M HCl). ...
Vermiculite enriched by Fe(III) oxides as a novel adsorbent for toxic metals removal
(Elsevier Sci Ltd, Oxford, 2021)
Expanded vermiculite (EV) was modified by deposition of different spinel ferrite composites on the outer surface of EV 2:1 layers in order to improve its adsorptive properties. Modifications were made by deposition of: ...
Removal of Pb2+ ions by raw corn silk (Zea mays L.) as a novel biosorbent
(Elsevier, Amsterdam, 2016)
There is no data about the corn silk usage as adsorbent for lead removal. In the present study, the corn silk (CS), without any modification, was investigated for adsorption of Pb2+ ions from aqueous solutions. The CS ...
Polymetallic mineralization of the Boranja orefield, Podrinje Metallogenic District, Serbia: zonality, mineral associations and genetic features
(Edizioni Nuova Cultura, Rome, 2013)
The Serbo-Macedonian Metallogenetic Province, part of the Alpine metallogenic belt, hosts several ore deposits in mainly three geotectonic units: the Vardar Zone, the Serbo-Macedonian massif, and to a lesser extend the ...
The adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto natural zeolites and clays: Clinoptilolite, bentonite and kaolin
(Elsevier, Amsterdam, 2013)
In this study, adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto clinoptilolite modified with sorbed metallic cations (Cu(II), Zn(II), Ni(II) or Mn(II)) have been probed. Natural ...
Some novel insights into the binding of oseltamivir and zanamivir to H5N1 and N9 influenza virus neuraminidases: a homology modeling and flexible docking study
(Srpsko hemijsko društvo, Beograd, 2009)
In the context of the recent pandemic threat by the worldwide spread of H5N1 avian influenza, novel insights into the mechanism of ligand binding and interaction between various inhibitors (zanamivir - ZMV, oseltamivir - ...
Uticaj sorpcije organskog katjona na tačku nultog naelektrisanja prirodnog zeolita / Influence of organic cations sorption on the point of zero charge of natural zeolite
(Savez hemijskih inženjera, Beograd, 2009)
U radu su prikazani rezultati modifikovanja površine prirodnog zeolita različitim količinama (2, 5 i 10 mmol M+/100 g) oktadecildimetil benzil amonijum jona (ODMBA). Dobijeni organozeoliti su označeni kao OZ-2, OZ-5 i ...
Uranium distribution in broiler organs and possibilities for protection
(Springer, New York, 2014)
The aim of the present study was to investigate the distribution of uranium (uranyl nitrate hexahydrate, UN) in muscle and organs (kidney, liver, and brain) of broilers, after a 7-day contamination with UN and administration ...
