Flocculation studies of natural quartz sample using anionic polyacrilamide
(Akademija nauka i umjetnosti Republike Srpske, 2019)
The waste sludge generated during processing of iron ore in the Omarska mine (Republika Srpska, Bosnia and Herzegovina) is fine-grained (<15μm), containing relatively high concentrations of iron, and quartz as its major ...
Binary oxide ceramics for enhanced phenols degradation under simulated Solar light
(Wiley, Hoboken, 2018)
Solvothermal synthesis of ZrO2-TiO2 binary oxides and pure counterparts at 150 degrees C in water/isopropanol media is presented. Titanium (IV) isopropoxide and zirconium (IV) propoxide were used as precursors. XRD and TEM ...
Preliminary data on the crystal-chemical characteristics of beryl from Cer Mt. (Serbia)
(Scientific Annals, School of Geology, Aristotle University of Thessaloniki, 2010)
A beryl crystal from Cer Mt. (Serbia) studied in this paper was characterized by means of
XRPD and wet-chemical analyses. It has following unit cell dimensions: a = 9.2166(8) Å, c = 9.192(1) Å, V = 676.2(1) Å3 and ratio ...
Chromium, Nickel, and Cobalt in soils of Srem and C. Banat
(Ecological Movement of Novi Sad, 2017)
This paper reports the concentration and sources of chromium, nickel and cobalt in soil samples from the Srem and Central Banat (Vojvodina, Serbia). Different methods were applied to identify the sources of elements and ...
Zirconium dioxide nanopowders with incorporated Si4+ ions as efficient photocatalyst for degradation of trichlorophenol using simulated solar light.
(Amsterdam : Elsevier Science BV, 2016)
We present a hydrothermal method for synthesis of zirconia nanopowders: pure and with incorporated Si4+ ions. Zirconyl chloride and tetraethyl orthosilicate were used as precursors. As prepared powders were annealed at 600 ...
Sonophotocatalytic degradation of dye CI Acid Orange 7 by TiO2 and Ag nanoparticles immobilized on corona pretreated polypropylene non-woven fabric
(Elsevier, 2015)
This study discusses the possibility of using corona pre-treated polypropylene (PP) non-woven fabric as a support for immobilization of colloidal TiO2 and Ag nanoparticles in order to remove dye C.I. Acid Orange 7 from ...
