Sinteza i karakterizacija materijala nastalih modifikacijom zeolita (klinoptilolita) i mikroporoznih fosfata sa strukturom zeolita [PDF]
, 2015 In the first part of the dissertation, the possibility of modifying the zeolitic tuff from the mine Zlatokop (near Vranjska Banja) was investigated in order to obtain new adsorbents. The second part presents the possibility of synthesize of new phosphate‐based microporous materials with structural properties of zeolites. The zeolitic tuff modified with

Las zeolitas naturales de España
, 2014 A pesar de su geología tan antigua, compleja y variada, España no posee grandes yacimientos de zeolitas. Los estudios realizados hasta la fecha sólo han revelado pequeños indicios relacionados con las formaciones volcánicas y volcanosedimentarias de la Península Ibérica y del Archipiélago Canario.

Potencijal primjene zeolita kao fungicida
Chemical fungicides are extensively used for the control of phytopathogenic fungi. However, the use of copper-based fungicides has been restricted by a European Commission regulation since 2002, and resistance of certain pathogens to some systemic fungicides has also been reported. Consequently, increasing attention is being given to the application of

Mokro usitnjavanje zeolita u planetarnom mlinu
, 2015 The aim of this work was comminution of the zeolite clinoptilolite to sizes smaller than a micrometer. Micronization increases specific surface area, adsorption capacity and ion exchange capacity of zeolite. Comminution was performed in planetary ball mill at different rotation speed (300, 400 and 500 rpm) at intervals of 10, 20, 30 and 60 minutes. The
