The adsorption of sulphate, hydrogenchromate and dihydrogenphosphate anions on surfactant-modified clinoptilolite
(Elsevier Science Bv, Amsterdam, 2000)
The adsorption of sulphate, hydrogenchromate and dihydrogenphosphate anions on surfactant-modified clinoptilolite (SMC) was investigated. The SMCs were prepared by the adsorption of cis-1-aminoctadecen-9 (oleylamine) on ...
Application of different collectors in the flotation concentration of feldspar, mica and quartz sand
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
The potential application of different cation collectors in the flotation concentration of mica, feldspar and quartz sand has been investigated. Raw materials (Bujanovac and Ub) from two localities in Serbia were used. The ...
Hydration of mechanically activated mixtures of Portland cement and fly ash
(University of Chemistry and Technology, Prague, 2007)
Fly ash (FA) can be used in cement mixtures with certain limitations. For experimental purposes, mixtures of Portland cement (PC) and FA were used. The content of FA in the mixtures was either 30% or 50%. The mechanical ...
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 ...
Influences of synthesis methods and modifier addition on the properties of Ni-based catalysts supported on reticulated ceramic foams
(Springer, New York, 2014)
A method of synthesizing Ni-based catalysts supported on alpha-Al2O3-based foams was developed. The foams were impregnated with aqueous solutions of metal chlorides under an air atmosphere using an aerosol route. Separate ...
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 ...
Chemical-technological processing of the complex barite-sulphide ore
(Blackwell Munksgaard, Copenhagen, 2003)
The investigation results of the processing possibilities of the complex barite-sulphide ore from "Bobija" deposit (Serbia) for the sake of lead, zinc and copper extraction are presented in this paper. Through x-ray ...
The nucleation behavior of k2o center dot tio2 center dot 3geo(2) undercooled melt
(University of Chemistry and Technology, Prague, 2009)
The nucleation of K2TiGe3O9 crystals in an undercooled melt of stoichiometric composition was studied. Volume nucleation with spherical morphology of the growing crystals was determined. The nucleation range is in the ...
Influence of Pr3+ and CO32- Ions Coupled Substitution on Structural, Optical and Antibacterial Properties of Fluorapatite Nanopowders Obtained by Precipitation
(MDPI, Basel, 2021)
Coupled substitution of fluorapatite (FAP) crystal lattice plays an important role in the engineering of optically active nanomaterials. Uniform fluorapatite nanopowders doped with praseodymium (Pr3+) and carbonate (CO32-) ...
Adsorption of mycotoxins by organozeolites
(Elsevier, Amsterdam, 2005)
Adsorption of zearalenone (ZEN), ochratoxin A (OCHRA) and aflatoxin B1 (AFB1) on natural zeolite, clinoptilolite, modified with different amounts of octadecyldimethylbenzyl ammonium (ODMBA) ions was investigated. Results ...
