AB  - Material SBA-15 with all of its particles in the form of regular spheres was synthesised by template method using
Pluronic P123 (non-ionic triblock copolymer) as a surfactant and tetraethoxysilane (TEOS, 98%) as a source of silica.
The synthesis of spherical SBA-15 was carried out in acidic conditions according to method proposed by Zhao et al.
Instead of expensive commercial cetyltrimethylammonium bromide as a co-surfactant, a spent HCl solution obtained
after the chemical treatment of clay in an aqueous solution of HCl was used. The mixture was aged at a higher
temperature. After that, the spherical SBA-15 was made by drying at room temperature after washing with distilled
water and then calcining in flowing air to decompose the triblock copolymer. The continual presence of spheres
of diameters around 2 μm in the entire SBA-15 was confirmed by scanning electron microscopy. The Energy-dispersive
X-ray spectroscopy confirmed that the spheres consisted only of SiO2 in composition. In addition, X-ray diffraction and
Fourier-transform infrared spectroscopy methods were used to characterise SBA-15 material. To assess the cytotoxic
effects of newly synthesised SBA-15 material, HEK 293 cells were treated with particles and extracts obtained from
particles incubated 24 hours at 37 °C in serum-free DMEM medium and DMEM with 10% serum. Cells were treated
with concentrations of 100, 250, and 500 µg/mL for 72 hours. All treatments reduced cell viability in a concentrationdependent manner (p<0.001). Cytotoxicity was more pronounced in particle treatment, indicating that mechanical
damage was induced in cells, whereas the extraction process influences the level of toxicity since the sera-free medium
had the mildest effect. To acquire safe particles for human use, additional synthesis optimisation is required.

AB  - The template method synthesis of both SBA-15 materials with elongated and spherical particles was performed using a surfactant Pluronic P123. The HCl (p.a.) was used to synthesize material with elongated particles connected in chain structures grouped into shapes resembling sheaves of wheat. In the synthesis of spherical SBA-15 with diameters ranging from 0.5 to 2 μm, a spent HCl solution which was obtained after chemical treatment of clay was used where the dominant presence of the spheres was confirmed by the SEM method. In addition to the methods mentioned above, XRD, EDS and FTIR methods characterize SBA-15 materials.

AB  - The  mining  basin  Kolubara  lies  about  50  km  southwest  of  Belgrade  and  stretches  across  the  river Kolubara from Lajkovac to its mouth in the Sava River. During coal exploitation a huge amount of clay is deposited as separate layer. Clay as a raw mineral material has a high economic potential due to their low price and high abundance.  This  material  is  used  for  various  applications  such  as  filters,  heat  insulators,  absorbents,  catalyst supports,  building  materialn  and  advanced  environmental  applications.  Clay  from  Kolubara  mining  basin  is caracterised  by  inductively  coupled  plasma  spectroscopy  (ICP),  X-ray  diffraction  (XRD),  Scanning  electron microscopy  (SEM).  Also,  activity  concentrations  of 40K,  226Ra and  232Th  in  clay  from  Kolubara  mining,  were determined by gamma ray spectrometry with HP Ge detector.

AB  - Diatomaceous earth is of sedimentary origin consists mainly of accumulated skeletons formed as a protective covering of the diatoms. Usually, high absorption capacity of diatomaceous earth provides its wide use as heat insulation, filter and absorbent material. Starting raw material diatomaceous earth from surface coal mine Kolubara, Serbia, was characterized using, scanning electron microscopy (SEM), X-ray diffraction (XRD). Chemical composition of diatomaceous earth was determined by wet chemical methods. In addition, the absorbed gamma ray dose rates is estimated based on the measured activity concentrations of natural radionuclides in clay were determined by gamma spectrometry. This research shows that this material is environmentally safe for further use.
