AB  - In this work, SrO and TiO2 were mechanochemically activated for 520 minutes. The X-Ray Diffraction Analysis determined that strontium titanate was obtained. The starting components reacted in an amount of 99.1%. Phase changes during the reaction were analyzed and the dynamics of mechanochemical synthesis were defined. The occurrence of an intermediate compound (activated complex) on the reaction path from the reactant to the stable product of the reaction was assumed and experimentally proven. The rate constant of the mechanochemical neutralization reaction between strontium oxide and titanium oxide is defined. A mathematical relation with the basic thermodynamic and other physicochemical parameters of the process was established.

AB  - This research evaluates the effects of the acid environment on sulfur-polymer composite. For this purpose, a morphology investigation consisting of mathematical morphology analysis and SEM analysis was performed. Based on the obtained results, insignificant changes in the pore system of sulfur-polymer composite in terms of deterioration, pore distribution, and homogeneity were observed. Namely, no signs of severe damage were detected at the surface and inside the samples. With increasing the acid exposure time, the material exhibited further changes in the direction of homogenization and drowning of the aggregate in the sulfur binder compared with the starting structure. These facts indicate that sulfur-polymer composite can be effectively used as a construction material in an acid environment.

By activating zeolite from natural mines in the Kopaonik area, it was determined that the activated zeolite becomes a calcium and magnesium donor.

AB  - In order to investigate the possibility of obtaining magnesium titanate, oxides of magnesium
and titanium were mechanochemically activated. Mechanical activation was performed for
1000 min in a high-energy vibro mill (engine power is 0.8 kV). The optimal amount of
powder activated in the mill is 50-100 g, so according to the stoichiometric calculation, the
composition of the starting mixture was 20.2 g (0.5 mol) MgO and 39.9 g (0.5). mol) TiO2.
X-ray diffraction analysis of samples taken from the reaction system was performed after 60,
180, 330 and 1000 min of mechanical activation. Atomic absorption spectrophotometry was
used to analyze the current chemical composition of the system, depending on the time of
activation. Based on the results of X - ray diffraction analysis, it can be concluded that the
greatest changes in the system occurred at the very beginning of mechanical activation due to
disruption of the crystal structure of the initial components. X-ray diffraction analysis of the
sample after 1000 min of activation showed complete amorphization of the mixture, but no
diffraction maxima characteristic of magnesium titanate was identified. Therefore, the
mechanical activation experiments were stopped. The fact is that the invested energy was not
enough to overcome the energy barrier for the formation of a new chemical compound -
magnesium titanate. The inability to synthesize magnesium titanate is explained by the low
negative Gibbs energy value of -25.8 kJ / mol (despite the theoretical possibility that the
reaction will occur), as well as the amount of mechanical energy that entered the system
during activation that is insufficient to obtain the reaction product. Although the synthesis of
MgTiO3 has not been achieved, significant results have been obtained that identify models for
further research into the possibility of mechanochemical reactions of alkaline earth metals and
titanium dioxide.

AB  - Bakar je jedan od najzastupljenijih metala u industriji zbog svoje najšire primene u poređenju sa ostalim obojenim metalima. Tokom procesa eksploatacije bakra stvara se velika količina rudničkih otpadnih voda. Zbog toga postoji sve veće interesovanje za rešavanje ekoloških pitanja industrije rudnika bakra. Hemijski sastav rudničkih otpadnih voda je složen i zavisi od hemijskog sastava rude koja se izlužuje tokom eksploatacije. Leteći pepeo je vrsta industrijskog otpada koji može da izazove višestruke ekološke probleme. S druge strane, zbog velike poroznosti i specifične površine, kao i drugih jedinstvenih karakteristika, leteći pepeo se takođe može koristiti kao jeftin i visoko efikasan adsorbens za prečišćavanje rudničkih otpadnih voda. U ovom radu leteći pepeo iz termoelektrane bez prethodnog tretmana i peletiziran korišćen je za sorpciju bakra iz otpadne vode. Rezultati su pokazali da je leteći pepeo efikasan sorbent bakra pri čemu su pelete imale tri puta veći adsorpcioni kapacitet u odnosu na mikronizirani pepeo.
AB  - Copper is one of the most present industrial metals due to its wide application compared to other non-ferrous metals. During the mining process of copper exploitation, large amount of mine waste water is generated. Therefore, there is a growing interest in solving the environmental issues of the copper mine industry. The chemical composition of these mine waste waters is complex and depends on the chemical composition of the ore that leaches during the exploitation. Fly ash is a type of industrial waste that can cause multiple environmental problems. On the other hand, owing to its high porosity, large specific surface area, and other unique characteristics, fly ash can also be used as a low-cost and high efficient adsorbent for treatment of mine waste waters. In this paper, fly ash from a thermal power plant without prior treatment and pelletized was used for sorption of copper from wastewater. The results showed that fly ash was an efficient copper sorbent, whereby the pellets had three times higher adsorption capacity compared to micronized fly ash.

The results showed there is increased content of iron in the form of Fe2O3, which reduces the clay quality.

lattice by the diffraction method. The analysis of the results showed a significant increase in the free

AB  - This paper covers the results of pelletizing fly ash in order to obtain pellets, with satisfied mechanical properties, that can be used in wastewater treatments. Serbian fly ash from “Nikola Tesla” power plant was used as a low cost sorbent. Fly ash was subjected to elementary and XRD analysis. Portland cement was used as a pelletizing agent along with the plastification agent. The mechanical properties of pellets were investigated using different methods such as: pressure resistance, impact resistance, resistance to abrasion, and disintegration in water. The best results were obtained with the addition of 10 % of cement along with the plasticizer.
