AFCF and clinoptilolite use in reduction of Cs-137 deposition in several days' contaminated broiler chicks
(Elsevier Sci Ltd, Oxford, 2007)
The objective of this study was to investigate the binding efficiency of AFCF and clinoptilolite, mixed to the feed and administered orally using gastric tube to chronically Cs-137 alimentary contaminated broiler chicks. ...
Određivanje arsena u rudama i jalovinama / The determination of arsenic in ores and tailings
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2007)
Arsen se pojavljuje kao prateći element sulfidnih ruda ležišta gvožđa, olova i drugih metala. Njegovo prisustvo u rudama je katkad u dovoljnim količinama da je ekonomski opravdano razmišljati o njegovoj eksploataciji. Kao ...

Competitive adsorption of polycyclic aromatic hydrocarbons on organo-zeolites
(Elsevier, Amsterdam, 2007)
Sorption of polycyclic aromatic hydrocarbons on organo-zeolites was investigated to determine sorbent-sorbate interaction. The hydrophobic character of the surface of the organo-zeolites was studied using in water vapor ...
Rare Pb-Bi sulfosalt mineralization from the Boranja orefield (Podrinje district, Serbia)
(E Schweizerbartsche Verlags, Stuttgart, 2007)
Pb-Bi sulfosalts are uncommon minerals in the deposits and mineralization of Boranja orefield (West Serbia), one of the less-known Serbian ore deposits. In the Kram locality the Pb-Bi sulfosalts occur typically in skarns ...
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 ...
