AB  - The accumulation of mine tailings in the mining area of Majdanpek represents a serious environmental problem. A strong impetus for the development of sustainable methods for the recovery of metals from mine tailings is given by the importance of heavy metal recovery and the economic benefits of precious and base metals. Currently, researchers are working to develop metals recovery from tailings through bioleaching, which is a more sustainable method compared to traditional metallurgical methods. Biotechnologies for leaching heavy metals from old flotation tailings (Majdanpek, Serbia) with fungus Aspergillus niger (A. niger) are discussed in this paper. The subject of this research is iron ions, since the tailings are the richest in this metal. With a simple bioleaching process, which is based on the cultivation of A. niger in the basic growth medium and then challenging it with tailings, 5% iron was released in 35 days. The transformation of mine tailings morphology was also confirmed by optical microscopy. Processes by which A. niger extracts metals from
tailings include acidolysis, complexation, alkaloysis and biosorption. Also, in addition to metabolites, these fungi produce spores and mycelium that can destroy material and transform it to the soil. Given that Serbia is abundant with agricultural
waste, as well as waste from the food industry, in future studies cheap waste should be used as an energy input source for A. niger and transformation of tailings.

AB  - Unappropriated disposing of unused drugs leads to an increase in their concentration in the
environment. Furthermore, wastewater treatment plants are not sufficient to prevent the
transport of drugs. Microplastics (MPs), which are also recognized as important pollutants,
can be divided into primary and secondary. The primary MPs are produced for commercial
purposes, while the secondary MPs are formed by the decomposition of plastic residues.
The hydrophobic nature and large specific surface area of MPs facilitate pollutants
binding. Animals misunderstand MPs for food and consume it, which could have harmful
health impacts because both MPs and adsorbed pollutants are ingested. In this paper, the
adsorption of the selected drugs - azithromycin, carbamazepine, sulfamethoxazole, and
diclofenac on low-density polyethylene (LDPE), polyamide (PA), and poly(ethylene
terephthalate) (PET) microplastics are presented. The experiment showed that drugs bind
best to PA and that azithromycin has the highest binding affinity.

Eksperiment je pokazao da se lekovi najbolje vezuju za PA, kao i da azitromicin ima najveći afinitet vezivanja.

AB  - Carbon materials of different structural and textural properties (multi-walled carbon nanotubes, carbon cryogel, and carbonized hydrothermal carbon) were used as adsorbents for the removal of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from aqueous solutions. Chemical modification and/or activation were applied to alter surface characteristics and to increase the adsorption and desorption efficiency of carbon materials. Surfaces of treated and untreated carbon materials were characterized through the examination of the textural properties, the nature of surface functional groups, and surface acidity. It was found that the adsorption capacity of tested carbon materials is not directly proportional to the specific surface area and the content of surface oxygen groups. However, a high ratio of surface mesoporosity affected the adsorption process most prominently, by increasing adsorption capacity and the rate of the adsorption process. Adsorption of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol followed pseudo-second-order kinetic model, while the equilibrium adsorption data were best fitted with the Langmuir isotherm model. Calculated mean adsorption energy values, along with the thermodynamic parameters, indicated that removal of selected hormones was dominated by the physisorption mechanism. High values of adsorption efficiency (88-100 %) and Langmuir adsorption capacities (29.45-194.7 mg/g) imply that examined materials, especially mesoporous carbon cryogel and multi-walled carbon nanotubes, can be used as powerful adsorbents for relatively fast removal of estrogen hormones from water.

abstract = "Carbon materials of different structural and textural properties (multi-walled carbon nanotubes, carbon cryogel, and carbonized hydrothermal carbon) were used as adsorbents for the removal of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from aqueous solutions. Chemical modification and/or activation were applied to alter surface characteristics and to increase the adsorption and desorption efficiency of carbon materials. Surfaces of treated and untreated carbon materials were characterized through the examination of the textural properties, the nature of surface functional groups, and surface acidity. It was found that the adsorption capacity of tested carbon materials is not directly proportional to the specific surface area and the content of surface oxygen groups. However, a high ratio of surface mesoporosity affected the adsorption process most prominently, by increasing adsorption capacity and the rate of the adsorption process. Adsorption of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol followed pseudo-second-order kinetic model, while the equilibrium adsorption data were best fitted with the Langmuir isotherm model. Calculated mean adsorption energy values, along with the thermodynamic parameters, indicated that removal of selected hormones was dominated by the physisorption mechanism. High values of adsorption efficiency (88-100 %) and Langmuir adsorption capacities (29.45-194.7 mg/g) imply that examined materials, especially mesoporous carbon cryogel and multi-walled carbon nanotubes, can be used as powerful adsorbents for relatively fast removal of estrogen hormones from water.",

AB  - U ovom radu biće prikazano dobijanje različitih adsorbenata na bazi polimernih mreža i gelova sa dodatkom nanočestica i njihova primena za prečišćavanje otpadnih voda od metala. Polimerne mreže i hidrogelovi kao adsorbenti predstavljaju novu alternativu za sistem tretmana otpadnih voda, ako se uzme u obzir da se mogu lako sintetisati sa željenim osobinama, i to od dostupnih i jeftinih sirovina. Dodatkom nanočestica u takvu polimernu
matricu nastaju nove klase multifunkcionalnih nanokompozitnih materijala, koji vrlo efikasno uklanjaju teške metale, radioaktivne elemente, boje, fenole i pesticide. U poređenju sa konvencionalnim adsorbentima, ovakvi superabsorbenti imaju niz prednosti kao što su visoki adsorpcioni kapacitet, velika brzina adsorpcije, mogućnost primene u širokom opsegu pH vrednosti, a potom i mogućnost desorpcije i ponovne upotrebe.
AB  - In this paper, the preparation of various adsorbents based on polymer networks
and gels with the addition of nanoparticles and their application for metal wastewater tre atment will be shown. Polymer networks and hydrogels as adsorbents represent a new alte rnative to the wastewater treatment system, given that they can be easily synthesized with thedesired properties, from available and inexpensive raw materials. The addition of nano particles to such a polymer matrix creates new classes of multifunctional nanocomposite
materials, which very efficiently remove heavy metals, radioactive elements, dyes, phenols and pesticides. Compared to conventional adsorbents, such superabsorbents have a number of advantages such as high adsorption capacity, high adsorption rate, the possibility of application in a wide range of pH values, and then the possibility of desorption and reuse.

AB  - The frequent usage of plastics in the consumer lifestyle has caused a problem that 
inventors of these polymers could not have foreseen. The discovery of microplastics as a pollutant present in the environment has become a global concern and has resulted in intensive research in this area. Microplastic is defined as any part of plastic with a diameter of 100 nm to 5 mm. Microplastics are all around us, in cosmetics, fibers of our clothes, water, and food, and it is even found in arctic ice. This review will describe why wastewater treatment plants (WWTPs) are suspected to be significant point sources of microplastic discharges into the aquatic environment.
