AB  - Fly ash (FA) is a by-product created from the burning of coal in thermal power plants. FA mainly consists of mineral compounds that make them naturally caustic. Despite this, research has shown that FA may be utilized as an alternative material in civil engineering, hydrotechnics and agronomy. Leaching tests may provide theoretical validation that FA may be used as an alternative sorbent or additive in construction material. In this paper, the results of up-flow percolation tests performed on raw FA as well as lime and cement modified samples (MFA) are presented. This method was chosen as it yields the most reliable assessment of releasing heavy metals under long-term exploitation. The research has focused on the leaching behaviour of Sb, As and Se in raw, lime and cement MFA samples. Raw FA was found to leach Se, As and Sb metal ions, cement modification did not prevent Sb and Se leachates, while lime-modified MFA was found to be the most stable material.

AB  - Zagađujuće materije iz otpadnih voda mogu se ukloniti različitim naprednim tehnikama prečišćavanja. Proces adsorpcije može se primeniti za uklanjanje teških metala iz otpadnih voda primenom brojnih materijala. U termoelektranama (TE) kao sporedni proizvod procesa sagorevanja uglja nastaju pepeo i šljaka. Cilj ovog rada je ispitivanje adsorpcionih svojstava pepela i šljake dodatkom cementa i kreča za uklanjanje jona teških metala (Cu2+, Zn2+, Pb2+ i Cd2+) iz vodenih rastvora. U radu su predstavljeni rezultati ispitivanja upotrebe modifikovanih oblika pepela i šljake kao adsorpcionog materijala. Najveću efikasnost uklanjanja ispitivanih jona pokazali su uzorci pepela i šljake iz TE Kostolac i TE Morava uz dodatak kreča, dok je uzorak pepela iz TE Kostolac uz dodatak cementa pokazao najmanji stepen izluživanja. Izvršena je selekcija materijala za dalja istraživanja koja obuhvataju optimizaciju procesa adsorpcije i karakterizaciju materijala.
AB  - Pollutants can be removed from wastewater by a variety advanced techniques for wastewater treatment. The adsorption process can be utilized for the removal of heavy metals from wastewater using numerous of materials. Fly ash and bottom ash are produced as a by-products of coal combustion in thermal power plants (TPP). The aim of this work has been to investigate the adsorption properties of a mixture made by adding cement and lime in fly ash and bottom ash to remove heavy metal ions (Cu2+, Zn2+, Pb2+ and  Cd2+) from aqueous solutions. This paper presents the results of a modified form of fly ash and bottom ash used as an adsorbent material. The highest removal efficiency of investigated ions has been found in samples of fly ash and bottom ash from TPP Kostolac and TPP Morava with the addition of lime, while the pattern of ash from TPP Kostolac with the addition of cement showed the smallest leaching level.    A selection of the material needs to be made in order to carry out further research that includs the optimization of the adsorption process and better char acterizing of adsorbent materials.

AB  - Various particles and materials, including pollutants, deposited on urban surfaces are washed off by stormwater runoff during rain events. The interactions between the solid and dissolved compounds in stormwater runoff are phenomena of importance for the selection and improvement of optimal stormwater management practices aimed at minimizing pollutant input to receiving waters. The objective of this research was to further investigate the mechanisms responsible for the partitioning of heavy metals (HM) between the solid and liquid phases in urban stormwater runoff. The research involved the collection of samples from urban asphalt surfaces, chemical characterization of the bulk liquid samples, solids separation, particle size distribution fractionation and chemical and physicochemical characterization of the solid phase particles. The results revealed that a negligible fraction of HM was present in the liquid phase (less than 3% by weight), while there was a strong correlation between the total content of heavy metals and total suspended solids. Examinations of surface morphology and mineralogy revealed that the solid phase particles consist predominantly of natural macroporous materials: alpha quartz (80%), magnetite (11.4%) and silicon diphosphate (8.9%). These materials have a low surface area and do not have significant adsorptive capacity. These materials have a low surface area and do not have significant adsorptive capacity. The presence of HM on the surface of solid particles was not confirmed by scanning electron microscopy and energy dispersive X-ray microanalyses. These findings, along with the results of the liquid phase sample characterization, indicate that the partitioning of HM between the liquid and solid phases in the analyzed samples may be attributed to precipitation processes.
