AB  - The pattern recognition approach, explored by this study, applies the principal component
analysis (PCA) as the most widely used statistical method with the aim of assessing the initiation
and propagation of the cracks and defects that appear on the surface of material exposed to the
cavitation. The experiment was performed in four stages: (a) synthesis of two ceramic materials
(cordierite and zircon); (b) subjecting the samples to the cavitation; (c) using image analysis
software for collecting the data about morphological characteristics that describe defects; (d)
principal component analysis as a pattern recognition tool in order to characterize the defects at
the material surface. Besides that, according to standard, cavitation erosion was monitored by
determining material mass loss during the cavitation. Large experimental datasets collected from
morphological descriptors by image analysis are multivariate and difficult to interpret, thus are
processed by principal component analysis as the most informative technique for extracting
possible differences. The performed approach proved that this method has a great potential for
better assessment of induced defects by proper distinguishing among them at different levels and
that can be considered a very efficient and cost-effective one.

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  - Stabilization of heavy metals, especially copper, from acidic mine wastewater is performed by their solidification into sulfur polymer concrete as an environmentally acceptable building material. The procedure is carried out by heating the aggregate in an amount of 56 mass % in a reaction vessel with continuous mixing up to a temperature of 160 °C. Subsequently 5 mass % of fly ash from the thermal power plant is added as a filler and 6 mass % of fly ash pellets with absorbed heavy metals from mine waters. Finally, 33 mass % of the sulfur modified binder, that is mixed melted elemental and modified sulfur in the mass ratio of 98.2 % : 1.8 % is added to the homogenized solid mixture. Modified sulfur is prepared by mixing the elemental sulfur that is by-product of oil refining with dicyclopentadiene at a temperature of 132-141 °C. After the homogenization of the sulfur polymer concrete mixture for 2-5 minutes, the resulting melted mixture is poured into the molds pre-heated to 120 °C and vibrated for 10 seconds. Thus obtained surface of the sulfur polymer concrete mixture is flattened and leave to harden in the mold at room temperature. The samples were removed from the mold after 3 hours of hardening and then cured at room temperature for another 24 hours. After characterization, obtained building material showed satisfactory properties required for all application areas of conventional concrete. By this process, heavy metals from mine wastewater were eliminated, industrial by-products (fly ash and sulfur) were used thus reducing their landfills, while the obtained material does not lead to secondary environmental pollution and therefore is considered as environmentally friendly.

Nakon 3 časa očvršćavanja uzorci se vade iz kalupa i neguju na sobnoj temperaturi tokom 24 časa. Dobijeni materijal je nakon ispitivanja pokazao zadovoljavajuće karakteristike potrebne za sve oblasti primene konvencionalnih betona. Ovim postupkom eliminisani su teški metali iz otpadnih rudničkih voda, korišćeni su industrijski nus-proizvodi (leteći pepeo i sumpor), čime su smanjene njihove deponije dok dobijeni materijal ne dovodi do sekundarnog zagađenja životne i stoga se smatra ekološki prihvatljivim., Stabilization of heavy metals, especially copper, from acidic mine wastewater is performed by their solidification into sulfur polymer concrete as an environmentally acceptable building material. The procedure is carried out by heating the aggregate in an amount of 56 mass % in a reaction vessel with continuous mixing up to a temperature of 160 °C. Subsequently 5 mass % of fly ash from the thermal power plant is added as a filler and 6 mass % of fly ash pellets with absorbed heavy metals from mine waters. Finally, 33 mass % of the sulfur modified binder, that is mixed melted elemental and modified sulfur in the mass ratio of 98.2 % : 1.8 % is added to the homogenized solid mixture. Modified sulfur is prepared by mixing the elemental sulfur that is by-product of oil refining with dicyclopentadiene at a temperature of 132-141 °C. After the homogenization of the sulfur polymer concrete mixture for 2-5 minutes, the resulting melted mixture is poured into the molds pre-heated to 120 °C and vibrated for 10 seconds. Thus obtained surface of the sulfur polymer concrete mixture is flattened and leave to harden in the mold at room temperature. The samples were removed from the mold after 3 hours of hardening and then cured at room temperature for another 24 hours. After characterization, obtained building material showed satisfactory properties required for all application areas of conventional concrete. By this process, heavy metals from mine wastewater were eliminated, industrial by-products (fly ash and sulfur) were used thus reducing their landfills, while the obtained material does not lead to secondary environmental pollution and therefore is considered as environmentally friendly.",

AB  - Numerous factors influence the complexity of environmental and waste management problems, and the most significant goal is the reuse of materials that have completed their “life cycle” and the reduction in the use of new resources. In order to reduce impact of waste slag on the environment, in the present study, waste slag, generated in heating plants after lignite combustion, was characterized in detail and tested for application as a replacement for cement in mortar or concrete production. For physical–chemical characterization of slag, different experimental and instrumental techniques were used such as chemical composition and determination of the content of heavy metals, investigation of morphological and textural properties, thermal analysis, X-ray, and infrared spectroscopy. Physical–mechanical characterization of slag was also performed and included determination of activity index, water requirement, setting time and soundness. A leaching test was also performed. Presented results show that waste slag may be used in mortar and concrete production as a partial cement replacement, but after additional combustion at 650 °C and partial replacement of slag with silica fume in the minimal amount of 12%. The maximal obtained cement replacement was 20% (17.8% slag and 2.2% of silica fume).

AB  - The intent in this paper is to define how the batch equilibrium results of copper removal from a synthetic solution on natural zeolite can be used for prediction of the breakthrough curves in the fixed-bed system for both a synthetic solution and wastewater. Natural zeolite from the Vranjska Banja deposit, Serbia, has been fully characterized (XRD, chemical composition, DTA/TG, SEM/EDS) as a clinoptilolite with cation exchange capacity of 146 meq/100 g. The maximum adsorption capacity (qm) in the batch of the mono-component system (synthetic copper solution) obtained using the Langmuir isotherm model was 7.30 and 6.10 mg/g for particle size below 0.043 and 0.6–0.8 mm, respectively. Using the flow-through system with the 0.6–0.8 mm zeolite fixed-bed, almost double the adsorption capacity (11.2–12.2 mg/g) has been achieved in a saturation point for the copper removal from the synthetic solution, compared to the batch. Better results are attributed to the constant high concentration gradient in flow-through systems compared to the batch. The complex composition of wastewater and large amounts of earth alkaline metals disturb free adsorption sights on the zeolite surface. This results in a less effective adsorption in flow-through systems with adsorption capacity in breakthrough point of 5.84 mg/g (~0.95 × qm) and in a saturation point of 7.10 mg/g (~1.15 × qm).

AB  - Recent investigations are focused on the possibility of waste utilization as potential adsorbents in wastewater treatments. Industrial by-products and wastes are almost zero-cost raw materials and at the same time, their utilization can contribute to the solution of management problem by improving the material efficiency within several industrial activities. Fly ash as a potential hazardous solid waste produced like a by–product in power plants worldwide in a million tons has attracted researches interest for years. Fly ash has potential application in wastewater treatment because of its major chemical components (alumina, silica, ferric oxide, calcium oxide, magnesium oxide, and carbon), and its physical properties such as porosity and large surface area. However, the micron particle size distribution of the fly ash (0.5 μm to 200 μm) that gives fly ash poor hydraulic properties is the one that limits the use of this material in wastewater treatments. This obstacle can be effectively overcome through the agglomeration process such as pelletization.  Fly ash can be efficiently pelletized using cement as a binder. For the production of pellets with satisfying mechanical properties, the required amount of cement as a binder is 10 %.  The dosage of plasticizer up to 3 % in relation to the amount of the cement, additionally improves the mechanical properties. Under the investigated pelletizing conditions, more than 80 % of the obtained pellets are suitable for the application in continuous systems for wastewater purification, form the particle size distribution point of view (1.0-5.0 mm). Obtained pelletized fly ash has been used as a sorbent for copper removal in a batch system. Copper adsorption by fly ash was examined using a range of initial Cu concentrations (25.0 to 600.0 mg/dm3). Solid liquid ratio was 100, and the investigated contact time was 120 min. After equilibration, all suspensions were centrifuged and the concentrations of the remaining Cu in supernatants were determined using AAS. The obtained results indicate that the rise of initial concentration leads to the higher adsorbed amount of the copper. The experimental data were analyzed using the Langmuir sorption model. According to this model, maximum adsorption capacity for copper removal by pelletized fly ash is 25.64 mg/g and this is almost 3 times higher capacity compared to the one non-pelletized (8.85 mg/g). The presence of cement leads to a higher pH value in the reaction solution (5.5-6.0) than in the one with micronized fly ash (4.6-5.1) and this higher pH values noticeably influence the removal efficiency.

AB  - This study is occupied by using fly ash for copper removal from the acid mine wastewater and a synthetic solution of similar composition. Chemical analysis of mine wastewater proved that the values of Cu, Zn, Fe, and Mn exceed the maximum accepted concentration in a large extent. Serbian fly ash from the “Nikola Tesla” power plant was used as a low-cost sorbent for the removal of copper ions (Cu2+) from aqueous solutions. Fly ash was subjected to elementary and XRD analysis. As a method, a batch sorption procedure was applied. Sorption efficiency was studied as a function of the contact time, and amount of the sorbent. Equilibrium was determined after 90 min for all investigated sorbent dosages.

AB  - Systematic modification of three structurally different minerals (zeolite, mica, and vermiculite) was carried out with the aim of determining the modification mechanism and exposing the hydrophobic surface that can be used as a sorbent for many organic compounds. Mechanism of modification with cationic surfactant depends strongly on the mineral type. In order to identify the influence of aluminosilicates structural differences on the modification process, adsorption experiments with organic matter and water vapor, supplemented with the DTA/TG analysis, were performed. The cation exchange capacity (CEC) value was 1454>560>28meqkg(-1) for zeolite (clinoptilolite), vermiculite, and mica (muscovite), respectively. Despite its CEC value, vermiculite adsorbed three times the amount of organic matter than did clinoptilolite due to the porous structure of zeolite, which acted to limit the adsorption only on the external exchangeable cations. If the loading amount is equal to the CEC or the external cation exchange capacity for clinoptilolite (ECEC approximate to 10% CEC), the monolayer will form while mineral surface will have hydrophobic character. Only one active center exists at the surface of the clinoptilolite that was identified by DTA curves with a sharp and defined peak around 300 degrees C and by the mass loss at the TG diagrams. Two significant and equal active centers were observed in vermiculite, one for the exchange of the surface cations and the other for the interlayer cations and H2O molecules. Muscovite CEC is negligible, and due to the absence of any other functional groups, the modification of this mineral was impossible.

AB  - Diverse industries produce fly ashes as thermal power plants, waste incinerators, and some recycling processes. Though some of these products can be raw materials for diverse applications, their composition can be hazardous due to their content in heavy metals. In addition, mixing fly ashes with the products of neutralization of fumes complicates the products. Then many fly ashes are landfilled in a Portland-cement matrix. However, most of the actual knowledge about their ageing derives from models the validity of which has been established only on the short term, using small sized proofs, at room conditions while matter transfers and reactions are strongly affected by temperatures reaching 80 °C for many years. Ageing leads to a mobility of chlorides, sulphates and lead, alteration of textural properties with formation of microcracks, formation of neo-formed minerals as silicatehydrates (katoite and hibschite, CSH), carbonates, tobermorite, hydrogarnets zeolites,…) that can contribute to bear Pb, Zn, Cr, Cu, in addition to inherited phases (metallic alloys, spinels, glasses, refractory oxides, titanates, phosphates,…). The alkaline hydrolysis of aluminium in saline media decreases the pH and promotes the precipitation of lead species trapped in a hydrocalumite or ettringite matrix.

AB  - In this paper the ability of three natural zeolites from different localities (Vranjska banja-VB, Igroš-I and Baia Mare-BM deposits) to remove copper has been investigated. These three zeolites were subjected to the elementary analysis as well as XRDP and DTA/TG analysis due to complete characterization. Cation exchange capacity of VB, I and BM zeolites were 150.1, 169.2, and 176.5 meq/100g. The maximum adsorption capacity for the copper adsorption on VB, I and BM-zeolites were 7.75, 8.51, and 11.18 mg/g. Based on the obtained results the mathematical expression that describes correlation between the CEC and copper adsorption capacity has been developed. This linear dependance has been tested with the vast variety of experimental results. According to this expression it is possible to predict the copper adsorption capacity for different zeolites based only on their CEC value.

AB  - The increasing levels of industrial wastewater released to the environment present a serious
threat to human health, living resources, and ecological systems. Fe-modified zeolites were developed and tested for removal of Cu2+ and Zn2+ from contaminated water. The surfaces of the naturally occurring zeolite, clinoptilolite, were modified with Fe(III) oxyhydroxides using three different methods, denoted I, II, and III (FeCli1 , FeCli2, and FeNaCli1, respectively). The oxyhydroxides were prepared in Method I using 0.1 M FeCl3 · H2O in an acetate buffer (pH = 3.6); in Method II, using 10% FeCl3 · H2O solution in 0.1 M KOH (pH = 10); and Method III was the same as Method I except the clinoptilolite was pretreated with NaCl. Newly synthesized materials from these three methods were then tested for their ability to enhance the sorption capacity for Cu and Zn compared to the natural sample (Cli). Powder X-ray diffraction measurements and the chemical composition of these modified samples confirmed that
clinoptilolite maintained its structure while amorphous Fe3+ species were synthesized. The specific surface area (BET method) of both the natural and modified clinoptilolite increased by 2 and 7.5 times for Methods I and II, respectively. Scanning electron microscopy and energy dispersive X-ray spectroscopy revealed that CaO was formed during Method I (FeCli1). Throughout the adsorption process, the hydrolysis of CaO and the release of OH¯ caused the precipitation of Cu and Zn hydroxide, which made the determination of the sorption capacity of FeCli1 impossible. This phenomenon was avoided in Method III (FeNaCli1) because of the absence of exchangeable Ca2+. The adsorption experiments with method II resulted in
double-enchanced adsoprtion capacity. Laboratory batch experiments have shown that the sorption capacities increased in the following order: Cli < FeCli2 < FeNaCli1, for Cu: 0.121 mmol/g < 0.251 mmol/g < 0.403 mmol/g and for Zn: 0.128 mmol/g < 0.234 mmol/g < 0.381 mmol/g.

abstract = "The increasing levels of industrial wastewater released to the environment present a serious
threat to human health, living resources, and ecological systems. Fe-modified zeolites were developed and tested for removal of Cu2+ and Zn2+ from contaminated water. The surfaces of the naturally occurring zeolite, clinoptilolite, were modified with Fe(III) oxyhydroxides using three different methods, denoted I, II, and III (FeCli1 , FeCli2, and FeNaCli1, respectively). The oxyhydroxides were prepared in Method I using 0.1 M FeCl3 · H2O in an acetate buffer (pH = 3.6); in Method II, using 10% FeCl3 · H2O solution in 0.1 M KOH (pH = 10); and Method III was the same as Method I except the clinoptilolite was pretreated with NaCl. Newly synthesized materials from these three methods were then tested for their ability to enhance the sorption capacity for Cu and Zn compared to the natural sample (Cli). Powder X-ray diffraction measurements and the chemical composition of these modified samples confirmed that
clinoptilolite maintained its structure while amorphous Fe3+ species were synthesized. The specific surface area (BET method) of both the natural and modified clinoptilolite increased by 2 and 7.5 times for Methods I and II, respectively.
