Adsorption of zearalenone on surface modified zeolites – clinoptilolite and phillipsite
(Croatian Zeolite Association, 2015)
Cetylpyridinum chloride (CP) was used to modify the surface of natural zeolites – clinoptilolite (Z) and phillipsite (P) and adsorption of zearalenone (ZEN) was investigated. Zeolites were modified with two different levels ...
Modified hybrid cellulose membrane for Nickel(ii) ions removal from industrial wastewater
(Bor : University of Belgrade, Technical Faculty in Bor, 2023)
Nickel pollution of water induces several problems for the environment. The purpose of this paper was to
investigate the adsorption of Ni2+ ions on fabricated biomembranes. The proposed adsorbent was prepared
from epoxy ...
Clay-chitosan-surfactant composites as efficient adsorbents of zearalenone
(Belgrade : Association of Metallurgical Engineers of Serbia, 2023)
In this study bentonite was modified with two chitosans, commercial or chitosan synthesized from mushroom. Obtained
products were subsequently treated with hexadecyltrimethyl ammonium bromide in the amount of 50% of the ...
Copper removal by pelletized fly ash
(Belgrade : University of Belgrade, Faculty of Mining and Geology, 2021)
The increasing levels of industrial wastewater that are released to the environment present a serious
threat to human health, living resources, and ecological systems. Fly ash was tested for removal of Cu2+ from
contaminated ...
Organophillipsite as potential low cost adsorbent for removal of ibuprofen
(Serbian Zeolite Association, 2019)
Zeolite – phillipsite was modified with long chain organic surfactant – hexadecyltrimethyl-ammonium bromide (HB). Two different amounts of HB were used to modify the zeolitic surface (150 % and 200% of phillisite external ...
Adsorpcija uranil-jona na modifikovanim klinoptilolitima / Adsorption of uranyl ion on acid-modified zeolitic mineral clinoptilolite
(Savez hemijskih inženjera, Beograd, 2009)
U ovom radu prikazani su rezultati ispitivanja adsorpcije uranil-jona na zeolitskom mineralu klinoptilolitu modifikovanom tretmanom kiselinama. Adsorpcija je praćena pri različitim količinama čvrste faze u suspenziji kao ...
Fumonisin B-1 adsorption to octadecyldimethylbenzyl ammonium-modified clinoptilolite-rich zeolitic tuff
(Elsevier, Amsterdam, 2007)
Adsorption of fumonisin B-1 (FB1) on natural clinoptilolite-rich zeolitic tuff, modified with different amounts (2, 5 and 10 mmol M+/100 g) of octadecyldimethylbenzyl ammonium (ODMBA) ions, at pH 3, 7 and 9, was investigated. ...
Adsorpcija jona bakra iz rudničkih otpadnih voda na različitim mineralnim adsorbentima / Adsorption of copper ions from mining Wastewater using different mineral adsorbents
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2015)
U ovom radu ispitivana je mogucnost primene prirodnog zeolita-klinoptilolita iz nekoliko ležišta: “Zlatokop” Vranjska Banja, “Igroš Vidojevic” Brus i “Baia Mare” Rumunija za adsorpciju jona bakra iz vodenih rastvora, kao ...
Adsorpcioni efekti mineralnih adsorbenata, III deo - ispitivanje u prisustvu vitamina B6 i mikroelemenata / Adsorpton effects of mineral adsorbents, Part III: Adsorption behaviour in the presence of vitamin B6 and microelements
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2000)
U ovom radu je ispitana in vitro adsorpcija vitamina B6 i mikroelemenata (Cu, Zn, Mn i Co) na mineralnim adsorbentima na bazi zeolita i bentonita. Mineralni adsorbenti na bazi zeolita su pokazali mali indeks vezivanja ...
Adsorption of ochratoxin A on octadecyldimethyl benzyl ammonium exchanged-clinoptilolite-heulandite tuff
(Elsevier, Amsterdam, 2003)
The in vitro adsorption of ochratoxin A (OCHRA) by clinoptilolite-heulandite rich tuff modified with different amounts -20, 50 and 100 mumol M+/g of octadecyldimethyl benzyl ammonium (ODMBA) ion was investigated. The ...
