AB  - The paper presents the results of synthesis and characterisation of refractory coatings based on various fillers
intended for the protection of metallic structures. Refractory
fillers applied are based on mullite, cordierite, zirconium
silicate, and pyrophyllite. Refractory filler samples are treated
by micronization grinding down to 15 m filler particles.
Methods as XRD, SEM, and optical microscopy are used
for characterisation. Performed tests determined the optimal
composition of protective coatings and manufacturing processes. According to standard ASTM G32 an ultrasonic vibrational method with stationary sample was used for characterising the obtained coatings. The goal of the research was
to determine the coating quality and its applications in
metallic surface protection in conditions of wear, corrosion,
cavitation, and high temperature. All coatings were tested
under the same conditions. A comparison of cavitation resistance is given for tested coatings. Coating quality is evaluated based on cavitation loss rate and on the analysis of
sample surface damage formation and development under
effects of cavitation.
AB  - U radu su prikazani rezultati sinteze i karakterizacije
vatrostalnih premaza na bazi različitih punioca namenjenih
za zaštitu metalnih konstrukcija. Korišćeni su vatrostalni
punioci na bazi mulita, kordijerita, cirkonijum silikata i
pirofilita. Uzorci vatrostalnih punioca podvrgnuti su mikronizirajućem mlevenju na veličinu zrna punioca 15 m. Za
karakterizaciju dobijenih punioca korišćene su metode XRD,
SEM i optička mikroskopija. Ispitivanjem je određen optimalni sastav zaštitnih premaza i postupci njihove izrade. Za
karakterizaciju dobijenih premaza primenjena je ultrazvučna
vibraciona metoda sa stacionarnim uzorkom prema standardu ASTM G32. Cilj ispitivanja bio je određivanje kvaliteta premaza i mogućnosti primene za zaštitu metalnih površina u uslovima habanja, korozije, kavitacije i povišenih temperatura. Svi premazi su ispitivani pod istim uslovima. Prikazan je uporedni pregled kavitacione otpornosti ispitivanih
premaza. Kvalitet premaza ocenjen je na osnovu vrednosti
kavitacione brzine, analize nastajanja i razvoja oštećenja
površine uzoraka pod dejstvom kavitacije.

AB  - In the paper, samples of protective coatings based on pyrophyllite were examined. The initial sample of
pyrophyllite was obtained from the Parsovići deposit, Konjic, Sarajevo, AD Harbi BiH. Pyrophyllite
samples were subjected to micronizing grinding to a filler grain size of 20 μm. XRD, SEM and optical
microscopy methods were used to characterize the obtained fillers based on pyrophyllite. The optimal
composition of protective coatings based on pyrophyllite and the manufacturing process were determined.
The resistance of refractory coatings to the effect of cavitation was experimentally determined using the
ultrasonic vibration method with a stationary sample according to the ASTM G32 standard. Based on the
value of the cavitation rate, the analysis of the formation and development of damage to the surface of the
samples, the possibility of applying a protective coating in the conditions of exploitation in which the
occurrence of corrosion and cavitation is expected was assessed.

AB  - Fluoride ions are increasingly present in the groundwater mainly due to the anthropogenic activity. On the other hand, increased awareness of harmful effects caused by high concentrations of F-in drinking water, leads to severe standards of water quality. Because of this, intensive researches of new methods for fluoride removal from water streams have been made in last decade. This paper examines the potential of aluminum alginate particles as a cheap and efficient biosorbent for F- removal. The adsorbent characterization before and after F- adsorption was performed using FT-IR technique. Adsorption experiments were conducted in a stirring batch mode, varying both concentration of adsorbate and adsorbent dose. Obtained result of 11,40 mg F-/g Al-alginate indicates a high adsorption capacity, while the kinetic parameters show fast removal kinetics.
AB  - Antropogeni faktor uslovio je sve veće prisustvo fluoridnih jona u podzemnim vodama. Sa druge strane, povećana svest o štetnosti visokih koncentracija ovog polutanta u pijaćoj vodi, dovela je do strožijih standarda kada su ovi joni u pitanju. Zato se poslednje decenije vrše intenzivna ispitivanja novih metoda za uklanjanje fluoridnih jona iz otpadnih i pijaćih voda. U ovom radu je ispitana mogućnost upotrebe aluminijum alginatnih čestica, jeftinog i efikasnog adsorbenta, za uklanjanje fluoridnih jona. Detaljna karakterizacija primenjenog adsorbenta urađena je pre i nakon adsorpcije primenom FT-IR tehnike. Eksperimenti su izvedeni u šaržnom sistemu sa mešanjem, pri različitim polaznim koncentracijama adsorbenta i adsorbata. Dobijen rezultat od 11,40 mg F-/g Al-alginata ukazuje na visok kapacitet adsorbenta, a kinetički parametri pokazuju brzu kinetiku uklanjanja ispitivanog polutanta.

AB  - The objective of this study was to investigate corncob as biosorbent for heavy metals removal from aqueous solutions. All biosorption experiments were performed in batch system. The biosorbent were caracterized by thermal analysis (DTA/TGA), Scanning Electron Microscopy and Energy Disperzive X-Ray analysis (SEM-EDX) and Fourier Transform Infrared Spectroscopy (FTIR) analysis. FTIR analysis of corn cob before and after Pb2+, Cu2+ and Zn2+ removal from aqueous solutions showed that ion exchange and chemisorption were involved in biosorption process of metal ions on to corn cob. Experimental data were fitted by Langmuir and Freundlich isotherm models. Maximum adsorption capacity of corn cob for Pb2+, Cu2+ and Zn2+ were 5,59; 2,62 i 1,23 mg/g, respectively. Desorption study showed that metal adsorbed corn cob can be effectively regenerated by HNO3 solution. Results from this study indicated that corn cob can be used as potential biosorbent for Pb2+, Cu2+ and Zn2+ removal from aqueous solutions.
AB  - Cilj ovog rada je ispitivanje mogućnosti upotrebe oklaska kukuruza za uklanjanje teških metala iz vodenih rastvora. Svi biosorpcioni eksperimenti izvođeni su u šaržnom sistemu. Karakterizacija biosorbenta izvršena je termijskom analizom (DTA/TGA), metodom skenirajuće elektronske mikro-skopije i energijsko-disperzivne rendgenske analize (SEM-EDX) i infracrvenom spektroskopijom sa Furijeovom transformacijom (FTIR). Na osnovu FTIR analize oklaska kukuruza pre i nakon uklanjanja Pb2+, Cu2+ i Zn2+ jona, ustanovljeno je da jonska izmena i hemisorpcija učestvuju u procesu biosorpcije jona metala na oklasku kukuruza. Eksperimentalni rezultati obrađeni su Lengmirovim i Frojndlihovim modelom izotermi. Maksimalni adsorpcioni kapacitet oklaska kukuruza za Pb2+, Cu2+ i Zn2+ iznosi 5,59; 2,62 i 1,23 mg/g, respektivno. Nakon ispitivanja procesa desorpcije zaključeno je da se adsorbovani joni metala na oklasku kukuruza efikasno i lako mogu ukloniti rastvorom HNO3.

AB  - In this study, carbonization products of grape pomace (hydrochar and process water) have been thoroughly characterized in order to assess its fuel properties, physico-chemical composition and to optimize its production. The obtained detailed insight into transformations of the biomass during hydrothermal conversion between 180-220 degrees C revealed that the hydrochar obtained at 220 degrees C exhibits a considerable energetic potential, increased porosity and re-adsorption abbility. Hydrothermally induced structural changes in the obtained hydrochars were unveiled by thermal and morphology analysis, FTIR and NIR spectroscopy. Temperature increment caused a decrease in antioxidative capacity, anthocyanin and organic acid content in process water and simultaneous increase in total phenolic and individual organic components content. The overall effect of the reaction temperature on products characteristics was assessed by multivariate data analysis. Obtained results substantiated the suitability of hydrothermal conversion of grape pomace into highly valuable fuels and versatile products.

AB  - Rapid techno-economic development, without adequate protection of the environment, caused a number of emergence problems: pollution, waste, loss of biodiversity, introduction of invasive species, release of o genetically modified organisms etc. Protection, conservation of natural resources and biodiversity requires an integrated approach to sustainable management. One approach is to stimulate the development of new biotechnology with an aim of saving and balanced usage of biodiversity. An increased industrial activity has intensified more environmental problems such as deterioration of several ecosystems due to the accumulation of pollutants. A vast array of biological materials, especially bacteria, algae, yeasts and fungi have received increasing attention for heavy metal removal due to their good performance, low cost and large available quantities. Biosorption has been defined as the property of certain biomolecules (or types of biomass) to bind and concentrate selected ions or other molecules from aqueous solutions. Biosorbents, unlike mono functional ion exchange resins, contains variety of functional sites. Advantages of these materials are their efficiency and low cost and application of biosorbents is good solution for removing metals, especially heavy metals from aqueous solutions. Different types of biosorbents that were considered for waste are getting a new application with extending product life cycle. Biosorption needs a multidisciplinary approach from the point of chemical, microbiological and process engineering, and allows a wider range of remediation techniques in relation to the ion exchange. This paper presents an overview of trends in biosorption and application of biosorbents for removing the pollutants (heavy metals and radionuclides) from contaminated effluents and water. .
AB  - Ubrzan tehno-ekonomski razvoj, bez adekvatne zaštite životne sredine, je prouzrokovao pojavu velikog broja problema: zagađenje, otpad, gubitak biodiverziteta, uvođenje invazivnih vrsta, oslobađanje genetski modifikovanih organizama, itd. Zaštita i očuvanje prirodnih dobara i biodiverziteta zahteva integralni pristup u održivom upravljanju. Jedan od pristupa je i stimulisanje razvoja novih biotehnologija u funkciji očuvanja i uravnoteženog korišćenja biodiverziteta. Povećana industrijska proizvodnja je dovela do ozbiljnih problema u životnoj sredini uzrokujući starenje nekoliko ekosistema zbog akumulacije polutanata. Veliko interesovanje u svetu postoji za biološkim materijalom, bakterijama, algama, kvascima i gljivama, kao biosorbentima za uklanjanje teških metala, zbog njihove niske cene, dobrih performansi i dostupnosti u većim količinama. Biosorpcija se može definisati kao sposobnost određenih biomolekula (ili tipova biomase) da vežu ili koncentrišu određene jone ili druge molekule iz vodenih rastvora. Biosorbenti za razliku od monofunkcionalnih jonoizmenjivača, sadrže različite funkcionalne grupe. Ovi materijali, kao jeftini ali efikasni adsorbenti, predstavljaju dobro rešenje za uklanjanje metala, posebno teških metala iz vodenih rastvora. Različite vrste biosorbenata koje su smatrane za otpad dobijaju novu primenu i produžava im se životni ciklus.
