AB  - The Republic of Serbia generates the majority of its electricity at the thermal power plants (TE) Nikola Tesla, Kolubara, and Kostolac. Coal is extracted from the Kolubara basin, which produces approximately 70% of lignite (an average of 30 million tons per year), and the Kostolac basin, which produces 30% of lignite. Ash, fly ash, and slag are examples of coal combustion residues. Because of the high content of potentially hazardous elements such as As, Pb, Cd, and Cr, environmental pollution with ash and fly ash has been extensively researched. Stable isotopes of lead can be used to trace lead sources. It is possible to monitor the presence, transformation pathways, and environmental impact of Pb by determining its isotopic composition in coal and fly ash. For the first time, the isotopic composition of selected coal samples from the Kolubara and Kostolac mines, as well as fly ash from the Kolubara (A and B), Kostolac (A and B), and Nikola Tesla (TENT A3, A2, B2) thermal power plants, was investigated in this study. The obtained data for 206Pb/207Pb in coal serve as the foundation for ranking domestic coals, whereas the isotopic ratios 206Pb/207Pb and 208Pb/207Pb  in fly ash can be used to monitor and control lead pollution from investigated sources.

AB  - This study investigated the use of different natural raw soil materials as low-cost adsorbents for the removal to remove As(V) and Pb(II) from aqueous systems. It deals with the effect of different soil textures, sandy loam, loam, and loamy sand, on adsorption efficiency. Fourier-transform infrared spectroscopy (FTIR) was used to carry out the comprehensive characterization of materials, as well as scanning electron microscopy (SEM), X-ray diffraction (XRD), and liquid nitrogen porosimetry or the Brunauer–Emmett–Teller (BET). Studies were performed in a batch system; the initial concentration of examined heavy metals was 100 μg·L–1, pH varied in the range of 4–6, and the adsorbent dosage was 5–20 mg/10 mL. Sandy loam was the most efficient adsor-bent for As(V) separation, with a maximum removal efficiency of 47.5%, while the loam was the most efficient for Pb(II) separation, with a maximum removal efficiency of 94.2%. The removal efficiency was affected mainly by the adsorbent characteristics. Performed kinetic studies revealed two steps of adsorption for both investigated ions. Obtained results indicate that natural sorbents used in this work present environmentally sustainable material for As(V) and Pb(II) removal, on the one hand, and the basis for further studies on the simultaneous removal of heavy metals from water and their reduced mobility in soil, on the other. © 2022 Desalination Publications.

AB  - The aim of this study was to examine the possibility of using natural unmodified materialsas adsorbents for efficient removal of Pb2+ions from aqueous solution. Two raw materialscomposed of SiO2, Al2O3 and Fe2O3, were analyzed. According to the textural classification the tested materials belong to sandy loam and loamy sand. In this research, X-ray diffraction analysis (XRD) and Fourier-Transform infrared spectroscopy (FTIR) were used for structural characterization of the materials. The process of adsorption of Pb2+ ions onto natural materials was conducted in a batch system. In order to determine optimal conditions, the mass of the adsorbent and the pH value of the solution were varied. Sandy loam and loamy sand have shown high efficiency for removing Pb2+ions from aqueous solution, without previous chemical modification. The efficiency of removal of lead ions on sandy loam and loamy sand is 88.2% and 80.2%, respectively, under optimal conditions (Ci(Pb2+)=100 μg L-1, mads=10 mg and pH 5). This study confirms that natural materials based on metal oxides can be used as effective adsorbents toremove cationic species of heavy metals from water systems.

AB  - Lead and arsenic represent an important group of inorganic pollutants that can be found in the environment, primarily in aquatic systems. Their removal from water systems is a big environmental problem, but also a significant technological challenge. Therefore, an increasing attention is paid to the development of widely available, efficient and environmentally friendly adsorbents. Natural metal oxide-based materials (SiO2, Al2O3, Fe2O3), such as loam, are effective adsorbents for removal of cationic and anionic species. The adsorption experiments were performed in a batch system, varying the pH value of the initial solution, while the mass of adsorbent, time and temperature were constant. The influence of pH value has a leading influence to the adsorption process so the process efficiency was determined at the pH values set at: 4, 5 and 6. The structural characteristics of the loam was performed using X-ray diffraction analysis (XRD), Fourier-Transform Infrared Spectroscopy (FTIR) and scanning electron microscopy (SEM). The concentration of ions after their removal was determined using inductively coupled plasma mass spectrometry (ICP-MS). The maximum removal of lead ions was obtained at pH 5 (94.2%), while for arsenic ions, it was at pH 6 (35.1%).
