A study of the primary crystallization of a mixed anion silicate glass
(Elsevier Science Bv, Amsterdam, 2008)
This paper presents the results of a study of the primary crystallization of a multicomponent mixed anion silicate glass. The primary phase, leucite, and the secondary phase, diopside, were formed by surface crystallization, ...
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 ...
Mineralogy of W-Pb-Bi ores from Rudnik Mt., Serbia
(E Schweizerbartsche Verlags, Stuttgart, 2006)
Polymetallic W-Pb-Bi ores have been found in the Nova jama ore zone of Rudnik Mt., Serbia. They are situated on the contact of quartzlatite dykes and breccias; mostly occur in a stockwork-type form. In this ore zone three ...
Improved materials for environmental application: Surfactant-modified zeolites
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
The surface properties of zeolites A, X, Y and natural zeolite clinoptilolite (CLI) functionalized by cationic surfactants were investigated. The quaternary ammonium type surfactants, such as hexadecyltrimethylammonium ...
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. ...
