AB  - A low-cost waste biomass generated from a food industry, apricot shells, was subjected to alkali modification in order to compare morphology, crystalline structure and thermal stability of native and modified biomass, accompanied by their cellulose-rich fractions. The surface morphology and structure of compared samples were analysed by the scanning electron microscopy (SEM) and mercury porosimetry. Furthermore, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermal analysis (TG/DTA) were applied. The results have shown that after alkaline treatment, inter- and intra-particle porosity in the material rises, resulting in increase of the total surface area. The XRD diffractograms showed that crystallinity index increased together with crystallite size, suggesting that modified sample has more ordered crystalline structure than native sample (also confirmed by the FTIR analysis). Although the cellulose-rich fraction extracted from the alkali-modified sample showed higher thermal stability, the overall thermal analysis revealed that alkali-modified biomass has lower thermal stability than the native sample. This indicates that this type of modification will improve the fuel properties of this lignocellulosic biomass and imply its possible application in energy recovery process.

AB  - This paper focuses on lignocellulosic waste biomass originating from food industry, which should find its further application in order to fulfill demands of circular economy. Therefore, here are presented some of the chemical and physical properties that affect combustion process, as well as thermochemical reaction kinetics for lignocellulosic biomass wastes. The biomass investigated was peach stone particles originating from food industry. The results have showed that peach stones can be characterized as good energy alternative renewable material, with properties that allow its safe thermochemical conversion. Kinetic analysis of this biomass was performed using Thermogravimetric Analysis (TGA) with a simple reaction model applied, namely n-th order reaction model. The obtained results have confirmed the complex nature of this material and the need for further modelling.

AB  - The goal of this study is to evaluate the quality of seven natural mineral water sources in the Vrnjačka Banja area used in the treatment of various diseases. The 24 macro- and microelements were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The results show that element content was within allowed limits of concentration, except for B, As, and Se. The evaluated content of these elements can be associated with geological and anthropogenic factors. The sample S6 contains more than twice the concentration of As, meaning that the use of water from this source should be limited due to the negative impact of this element on human health. The calculated values of weekly (EWI) and oral (OI) intakes as well as the acute hazard quotient (HQA) of selected toxic and potentially toxic elements indicate no health risks to the consumers. The highest hazard quotient (HQL) observed for As in sample S6 (2.0·10−1) demonstrated a significant risk of carcinogenic diseases in long-term consumption from this source. The estimated non-carcinogenic (DIA) and carcinogenic (DIL) dermal intakes with acute (HQA) and long-term (HQL) hazard quotient values for sample S3 show that there is no health risk to those who use the water from this thermal source for bathing. The presence of aerobic mesophilic bacteria at 22 °C and 37 °C in samples S3, S6, and S7 as well as sulphite-reducing Clostridia species in sample S5 were detected, potentially indicating some non-faecal or faecal contamination.

AB  - Adsorption is one the best commonly used technique for treatment of petroleum contaminated water. The biosorption potential of waste biomass (peach shell, agro-industrial waste) as a low-cost biosorbent for petroleum hydrocarbon from aqueous solution was explored. Biosorption experiments were carried out using a shake-flask technique with a constant amount of (bio) sorbent of 1 g mixed with 100 ml of water contaminated with petroleum hydrocarbons at concentrations of 4 mg/L, 12 mg/L, 18 mg/L, 24 mg/L, 30 mg/L, 40 mg/L and 80 mg/L. The obtained results show that waste biomass is efficient in the removal of petroleum pollutants from the water solution. Biosorption is a potentially alternative technique for wastewater treatment. Their major advantages are low cost, high efficiency, renewability.
AB  - Adsorpcija je jedna od najčešće korišćenih tehnika za tretiranje voda zagađenih naftom i njenim derivatima. U radu je ispitivana mogućnost primene otpadne biomase (koštice breskve, agroindustrijskog otpada), kao jeftinog biosorbenta, za uklanjanje nafnih zagađivača iz vodenog rastvora u stacionarnim uslovima. Biosorpcioni eksperimenti su obavljeni u erlenmajerima na na orbitalnom šejkeru u kojima je konstantna količina biosorbenta od 1 g mešana sa 100 ml vode kontaminirane naftnim ugljovodonicima u koncentacijama 4 mg/L, 12 mg/L, 18 mg/L, 24 mg/L, 30 mg/L, 40 mg/L and 80 mg/L. Dobijeni rezultati pokazuju da je otpadna biomasa efikasna u uklanjanju naftnih polutanata iz vodenog rastvora. Biosorpcija je potencijalno alternativna tehnika za prečišćavanje otpadnih voda. Njene glavne prednosti su niska cena, visoka efikasnost i obnovljivost.

AB  - Locally available apricot (Prunus armeniaca L.) shells classified as a waste product from fruit processing, were alkali activated in order to develop an efficient heavy metal ions sorbent for water purification. To examine the changes occurred after alkali treatment, raw (SH) and modified apricot shells (SHM) were thoroughly characterized in terms of their chemical composition and surface properties. Chemical analysis revealed that alkaline treatment causes the disintegration of hemicellulose (its content decreased from 19.2 to 3.5%), which was in accordance with FTIR results. SEM micrographs and the mercury intrusion porosimetry revealed a larger surface area and porosity of SHM. Bohem's acid-base titration method indicated that the most of the SHM surface carboxylic groups were in sodium salt form and together with the pH of points of zero charge showed increase of surface alkalinity after modification. Treatment with NaOH enhanced the adsorption capacity by 154, 61 and 90% for Cu2+, Zn2+ and Pb2+, respectively. The amount of cations released from SHM was almost equal to the amount of adsorbed metal ions, suggesting ion exchange mechanism. The pseudo-second order kinetic indicated that the heavy metals cations were bound predominantly by complexation. In order to establish the effectiveness of the biosorbent in real wastewater sample, SHM was employed for cleaning-up of drain water emanating from atomic adsorption spectrophotometer. The SHM showed high removal efficiency towards multiple metal ions. The amounts of Fe, Pb, Cu and Cr ions were reduced by 97, 87, 81 and 80%, respectively, while Ni and Zn amounts were reduced for 33 and 14%. Used biosorbent SHM can be successfully regenerated with HCl (desorption > 95%) and after regeneration biosorbent can be reused or it can be safely disposed.

Chemical analysis revealed that alkaline treatment causes the disintegration of hemicellulose (its content decreased from 19.2 to 3.5%), which was in accordance with FTIR results. SEM micrographs and the mercury intrusion porosimetry revealed a larger surface area and porosity of SHM. Bohem's acid-base titration method indicated that the most of the SHM surface carboxylic groups were in sodium salt form and together with the pH of points of zero charge showed increase of surface alkalinity after modification. Treatment with NaOH enhanced the adsorption capacity by 154, 61 and 90% for Cu2+, Zn2+ and Pb2+, respectively. The amount of cations released from SHM was almost equal to the amount of adsorbed metal ions, suggesting ion exchange mechanism. The pseudo-second order kinetic indicated that the heavy metals cations were bound predominantly by complexation. In order to establish the effectiveness of the biosorbent in real wastewater sample, SHM was employed for cleaning-up of drain water emanating from atomic adsorption spectrophotometer. The SHM showed high removal efficiency towards multiple metal ions. The amounts of Fe, Pb, Cu and Cr ions were reduced by 97, 87, 81 and 80%, respectively, while Ni and Zn amounts were reduced for 33 and 14%. Used biosorbent SHM can be successfully regenerated with HCl (desorption > 95%) and after regeneration biosorbent can be reused or it can be safely disposed.

AB  - The aim of this study was to evaluate the content of trace elements and physicochemical properties of water samples in the territories of southern Banat and Zemun (Serbia). The contents of twenty-two macro- and microelements were determined using ICP analysis. Prior to this, the typical parameters were evaluated using standard analytical methods. The contents of elements in all studied samples were within the maximum allowed concentrations established by national regulations on the water quality for human use of examined elements, except for Na, Fe, B, Mn, As and Co. The most of elevated metal concentrations were recorded in the samples from Zrenjanin area, with special emphasis on increased concentrations of arsenic. Besides, the higher concentrations of iron and manganese were found in samples S03 and S04, respectively. The increased concentrations of iron, arsenic and manganese in the samples from southern Banat area could be explained by the presence and reductive dissolution of some iron minerals in the subsurface which could contain As or Mn as trace elements. Increased concentration of boron could be the consequence of its leaching from ground caused by the adequate pH value. The obtained results indicate that geology of terrain might be the main cause of elevated concentrations of iron, boron, arsenic and manganese in the study region. Potential human weekly and long-term health risk was determined and expressed through exposure risk assessment. It has been found that only arsenic in sample S07 represents a great weekly risk. On the long-term basis, consumption of waters with elevated concentrations of boron/S05-08/ and manganese/S04, S07 and S08/ can be considered as high health risk. Our study indicates that both risk assessments need to be done, in order to better understand the real risk of increased concentrations of harmful elements on human health.

AB  - Procedures for solubilization of phosphorus from insoluble phosphates by acidophilic autotrophs and heterotrophs are considered to be research subjects of great importance in sustainable soil management, and could become, in the future, an alternative to current expensive methods of industrial fertilizer production. Furthermore, this biological production of fertilizer can be considered to be more environmentally friendly than current production methods. The object of this study was to investigate the possibility of phosphorus leaching from phosphate rock apatite using sulphuric acid generated from pyrite by iron-oxidizing Acidithiobacillus sp. B2, and to test the possible application of the mixture of these two minerals to produce a natural phosphate fertilizer. Iron-oxidizing Acidithiobacillus sp. B2 was isolated from copper sulphide mine wastewater (Lake Robule) in Bar, Serbia. The bacterium was identified by 16SrDNA oligonucleotide sequence and characterized using matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy (MALDI-TOF MS). The leaching experiment was carried out in laboratory conditions at 28 degrees C for a period of four weeks. The results showed that up to 34.5% of the inorganic phosphorus was leached from the test mixture when in suspension with iron-oxidizing Acidithiobacillus sp. B2, while at the same time, the degree of leaching from a control suspension (without iron-oxidizing Acidithiobacillus sp. B2) was only up to 3.8%. Due to its low cost and environmental acceptance, treatment of soil with phosphate minerals in combination with pyrite and acidophilic iron- and sulphur-oxidizing bacteria could become an attractive and alternative way to improve the quality of alkaline soils.

AB  - Phosphorus solubilization from insoluble phosphate ores by acidophilic autotrophs and heterotrophs is a research of significant interest, because of potential use of these ores as fertilizers, which are economically and ecologically more acceptable than industrial phosphate fertilizers. The object of this paper was to examine the possibility of phosphorus leaching from phosphate ore from Lisina deposit (Bosilegrad), by bacterially generated sulfuric acid, in laboratory conditions. The experiments were carried out with bacterium Acidithiobacillus (At.) ferrooxidans, which is isolated and selected from the copper sulphide mine in Bor. The main goal of the experiment was to confirm if it is possible to use phosphate ore in combination with examined bacterial culture, as a natural fertilizer. Results obtained show that phosphorus has been leached up to 24,5 % in suspension with At. ferrooxidans, and in the same time, degree of leaching in control suspension (without At. frrooxidans) was up to 7,2 %. Influence of At. ferrooxidans on phosphorus solubilization has been confirmed, so the future perspective of our investigations should be directed to examination of microbiological leaching of apatite mixtures with sulphide substrates, and their potential use in quality improvement of alkaline soils.
AB  - Postupci rastvaranja fosfora iz nerastvornih fosfatnih ruda pomoću acidofilnih autotrofa i heterotrofa spadaju u veoma bitna istraživanja, zbog moguće primene ovih ruda kao đubriva, čija je upotreba ekonomski i ekološki prihvatljivija od industrijskih fosfatnih đubriva. Predmet ovog rada je bio da se ispita mogućnost rastvaranja fosfora iz fosfatne rude sa ležišta Lisina (Bosilegrad), u laboratorijskim uslovima, dejstvom sumporne kiseline generisane pomoću bakterijske kulture Acidithiobacillus (At.) ferrooxidans, izolovane i selekcionisane sa jalovišta površinskog kopa rudnika bakra u Boru. Cilj eksperimenta je da se utvrdi da li je moguće rudu sa navedenog ležišta u kombinaciji sa ispitivanom bakterijskom kulturom koristiti kao prirodno đubrivo. Dobijeni rezultati pokazuju da se tokom eksperimenta rastvara fosfor iz ispitivane rude pod uticajem At. ferrooxidans i da je stepen rastvaranja 24,5 %, dok je rastvaranje fosfora u kontrolnoj suspenziji (bez At. ferrooxidans) iznosilo 7,2 %. Uticaj At. ferrooxidans na rastvaranje fosfora je potvrđen, tako da dalja istraživanja treba usmeriti na ispitivanja mikrobiološkog luženja mešavina apatita sa sulfidnim supstratima, zbog eventualne primene vezane za poboljšanje kvaliteta alkalnih zemljišta.

abstract = "Phosphorus solubilization from insoluble phosphate ores by acidophilic autotrophs and heterotrophs is a research of significant interest, because of potential use of these ores as fertilizers, which are economically and ecologically more acceptable than industrial phosphate fertilizers. The object of this paper was to examine the possibility of phosphorus leaching from phosphate ore from Lisina deposit (Bosilegrad), by bacterially generated sulfuric acid, in laboratory conditions. The experiments were carried out with bacterium Acidithiobacillus (At.) ferrooxidans, which is isolated and selected from the copper sulphide mine in Bor. The main goal of the experiment was to confirm if it is possible to use phosphate ore in combination with examined bacterial culture, as a natural fertilizer. Results obtained show that phosphorus has been leached up to 24,5 % in suspension with At. ferrooxidans, and in the same time, degree of leaching in control suspension (without At. frrooxidans) was up to 7,2 %. Influence of At. ferrooxidans on phosphorus solubilization has been confirmed, so the future perspective of our investigations should be directed to examination of microbiological leaching of apatite mixtures with sulphide substrates, and their potential use in quality improvement of alkaline soils., Postupci rastvaranja fosfora iz nerastvornih fosfatnih ruda pomoću acidofilnih autotrofa i heterotrofa spadaju u veoma bitna istraživanja, zbog moguće primene ovih ruda kao đubriva, čija je upotreba ekonomski i ekološki prihvatljivija od industrijskih fosfatnih đubriva. Predmet ovog rada je bio da se ispita mogućnost rastvaranja fosfora iz fosfatne rude sa ležišta Lisina (Bosilegrad), u laboratorijskim uslovima, dejstvom sumporne kiseline generisane pomoću bakterijske kulture Acidithiobacillus (At.) ferrooxidans, izolovane i selekcionisane sa jalovišta površinskog kopa rudnika bakra u Boru.
