Petrological and geochemical composition of lignite from the D field, Kolubara basin (Serbia)
(Elsevier, 2013)
The Upper Miocene lignite from the Main coal seam in the D field, Kolubara basin, is a typical humic coal with huminite, liptinite and inertinite concentrations of up to 83.7 vol.%, 17.2 vol.% and 15.5 vol.%, respectively. ...
Synergic adsorption of Pb2+ and reactive dye-RB5 on two series of organomodified bentonites
(Elsevier, 2013)
Two series of organobentonites (OBs) were synthesized from Na+-exchanged bentonite clay from Bogovina, Serbia. In the first series the starting material was modified using hexadecyltrimethylammonium (HDTMA(+)) ion in the ...
Associations and Pollution Potential of Selected Trace and Major Elements in Filter Lignite Ash from the "Nikola Tesla A" Power Plant (Obrenovac, Serbia) (I) - Leaching Experiments
(Taylor & Francis Inc, Philadelphia, 2013)
Serbia obtains most of its energy from low-quality lignite, thus being one of the world's largest producers of coal ash per capita. In order to examine the distribution of trace and major elements in the ash and the pollution ...
