AB  - In this study, iron oxide nanoparticles immobilized within alginate gel exhibited promising potential for the removal of arsenic (V) ions. The preparation of the polymer-oxide composite  was achieved by the ionic crosslinking of an alginate/iron oxide solution with a calcium (II)ions solution. The maximum amount of arsenic adsorbed by the investigated composite under the experimental conditions was slightly above 26 mg/g in 120 min. The results indicated that arsenic adsorption by this composite material follows a fast kinetic profile, adhering to a pseudo-second-order model. The adsorption process occurs in multiple stages, as suggested by the Weber-Morris model, with external diffusion dominating initially, followed by intraparticle diffusion. Importantly, the results confirmed that the use of alginate gel does not significantly impact the adsorption process, preserving the adsorption capacity of the metal oxides. Overall, the investigated composite successfully removed arsenic (V) from the solution, addressing a critical issue in water treatment.

AB  - Peach stones, a valuable agro-industrial by-product available in many countries worldwide,
comprise a renewable resource, which can be widely applied for multifunctional purposes.
Its important advantages such as high-energy value, low ash content, low price and wide
abundance, make peach stones an ideal fuel for energy production, but also for new
materials synthesis. Although peach stones exhibit adequate combustion properties,
allowing their direct use with minimal physical/chemical treatment, they often need further
modification in order to improve their thermal properties, where slow pyrolysis is frequently
used. This study aims to provide a practical and effective solution to the revalorization of
waste biomass originating from the fruit processing industry, through slow pyrolysis in order
to convert this waste into carbonaceous material – biochar. The thermo-chemical conversion
of raw biomass resulted in a stable material with excellent fuel properties, with higher mass
energy density and grinding ability, providing biochar with properties, in energy sense,
similar or even better than a coal. Biochar has a higher fixed carbon content and a higher
energy potential than biomass itself, and its application as a biofuel might reduce emissions
of greenhouse gases, as it reduces the amount of waste landed and increases the share of
energy generated from renewable sources.
AB  - Koštice breskve, otpadna biomasa poreklom iz industrije prerade voća, dostupna u mnogim zemljama širom sveta, predstavlja obnovljivi resurs koji može imati različitu primenu. Prednosti koje se ogledaju u velikom energetskom potencijalu, malom sadržaju pepela, niskoj ceni i širokoj rasprostranjenosti, čine koštice breskve idealnim resursom za proizvodnju energije, ali i za sintezu novih materijala.

Biočađ poseduje znatno veći energetski potencijal od same biomase, i njegova primena kao biogoriva može redukovati emisiju gasova sa efektom staklene baste, pri čemu se istovremeno smanjuje količina deponovanog otpada ali i povećava udeo energije generisane iz obnovljivih izvora.

AB  - In this study, the use of low-cost, widely available waste biomass of sour cherry stone (CS) was
used for the production of biochar (CSB), and used as an alternative to the expensive removal
techniques for removing toxic dye Brilliant green (BG) from wastewater. Produced CSB was
characterized using Fourier Transform Infrared spectroscopy with attenuated total reflectance
(FTIR-ATR) and Thermogravimetric method (TG-DTG). FTIR-ATR results indicated the
evolution of aromatic functional groups replacing aliphatic groups of CS. The effects of various
operational parameters (pH, contact time, initial dye concentration, adsorbent dosage and
temperature) were investigated and optimal conditions were determined. According to the results,
optimized parameters were: pH 6, contact time of 120 min, initial dye concentration of 50 mg/L,
adsorbent dosage of 2 g/L, and temperature of 35 ℃. These parameters were used for kinetic and
isothermal investigations. The adsorption of BG was evaluated using two kinetic reaction models
(pseudo-first-order and pseudo-second-order). The results showed that the pseudo-second-order
model fitted better the experimental data, indicating chemisorption involving valence forces
through the exchange of electrons between the dye and CSB. According to the adsorption isotherm
analysis, the Langmuir isotherm model better fits experimental data than the Freundlich and Sips
models. The maximum monolayer adsorption capacity of BG on CSB was found to be 109.25
mg/g. The RL value (0.392) verifies that the BG adsorption on CBS is a feasible process. Using
CS as a raw material for biochar production, the problem of waste disposal, its decomposition and
secondary pollution might be solved. In the same time, this waste materials would gain not only
ecological but also significant economic value. These findings demonstrated that CSB, which is
made from waste biomass, can be used as a promising and affordable adsorbent for removing dyes
from aqueous solution.

AB  - The presence of arsenic in drinking water above the permissible limits is one of the current problems facing modern
engineers in the field of separations and it has not yet been satisfactorily resolved, because the permissible concentrations
of arsenic in drinking water are constantly reduced by the World Health Organization (WHO). Among the various
processes for arsenic removal, adsorption has a special place as one of the most efficient and cheap process. Many natural
and artificial materials are tested for adsorption processes, and adsorption on metal powders is particularly interesting
because they represent adsorbents with fast kinetics and relatively high adsorption capacities. However, the application
of powder adsorbents is difficult due to their separation from the mixture after adsorption. In order to solve that problem,
metal powders may be immobilized into particles obtained by gelling natural polymers. In this way, it is easier to separate
the adsorbent from the mixture, however this must be achieved without losing the adsorption capacity and rate compared
to pure metal powders.
In this study, the use of metal oxide (iron oxide nanoparticles) immobilized within the alginate gel showed good potential
for arsenic (V) ions removal. The obtained results showed that arsenic adsorption by obtained composite has fast kinetic,
following pseudo-second-order model, and that it is conducted in several steps, according to the Weber-Morris model. It
was suggested that external diffusion is the dominant mechanism at the beginning of the arsenic adsorption, followed by
intraparticle diffusion. The obtained results confirmed that gelling with alginate did not significantly affect the adsorption
process, that is, it does not interfere with the adsorption capacity of metal oxides, which is a very important factor. Arsenic
(V) removal was successfully performed using the investigated composite.

AB  - In this study, slow pyrolysis was employed for the thermochemical conversion of peach stones (PS), lignocellulosic waste (LCW) from food industry, to prepare biochar (PS-B), a new and efficient sorbent for the removal of toxic dye, brilliant green (BG), from aqueous solution. Detailed characteristics of PS and PS-B were analysed using pH suspension, pHPZC, zeta potential, particle size distribution, thermogravimetric method (TG-DTG), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM–EDX), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The results revealed that material loss during slow pyrolysis not only altered the chemical structure of the samples, but also induced the volume shrinking phenomenon, resulting in production of a rougher, porous structure with decreased crystallinity. Also, five times less total organic carbon (TOC) release was demonstrated by biochar compared to native material. Comparison of experimental results for BG sorption by PS and PS-B showed that sorption capacity increased after pyrolysis and that sorption kinetic was significantly improved. The BG sorption by both sorbents followed the pseudo-second-order reaction kinetic model, with the intraparticle diffusion model within pores controlling the adsorption rate in PS-B. Isotherm equilibrium modelling revealed that the Sips isotherm provided the best model fit with maximum sorption capacity of 82.53 and 101.11 mg/g for PS and PS-B, respectively. A possible sorption mechanism of BG was achieved through pore filling (porous diffusion), hydrogen bonding, electrostatic attraction and π-π interactions. The results demonstrated that biochar derived from peach stones can be used as a promising green material for removing BG from contaminated waters.

The results demonstrated that biochar derived from peach stones can be used as a promising green material for removing BG from contaminated waters.",

AB  - Annually, around 1.4 billion tonnes of food worldwide is classified as waste. This waste,
usually disposed at landfills, poses a serious threat to both the environment and human
health. With appropriate modifications, food waste can be converted into value-added
products for the removal of organic and inorganic contaminants from aqueous solutions. In
this study food waste (peach, cherry and plum stones) were modified with MgCl2 and
pyrolyzed to produce biochar, a multifunctional highly porous carbon rich material with
improved properties for phosphate (PO43-) removal. The samples were categorized using the
Fourier transform infra-red (FTIR-ATR) technique, point of zero charge (pHpzc) and pH
suspension (pHsus). The experimental sorption results revealed that the modified plum stone
biochar (PSB-M) has higher sorption capacities than other materials. Kinetic adsorption
experiments demonstrated that the pseudo-second-order model was the most suitable one for
PO43- adsorption on PSB-M. The production of such a sorbent can be affordable considering
that the raw material is regarded as waste. Therefore, the findings of this research can be a
foundation for the synthesis of an effective phosphate sorbent, whose properties and
maximum sorption capacity should be further researched.

AB  - Peach stones, a valuable agro-industrial by-product available in many worldwide countries,
comprise a renewable resource, which can be widely applied for multifunctional purposes. Its
important advantages such as high-energy value, low ash content, low price and abundance, make
peach stones an ideal fuel for energy production, but also for new materials synthesis. Although
peach stones pose properties, which allow them to be used with minimal physical/chemical
treatment, they often need further modification in order to improve their thermal properties, where
slow pyrolysis is frequently used. This study aims to provide a practical and effective solution to the
revalorization of wasted biomass originating from the fruit processing industry, through slow

AB  - Serious environmental problem worldwide are effluent waters from many industries, such
as mining, refining ores, pesticide, batteries, paper industries, etc., containing toxic
components, mostly heavy metals, which are not treated properly in many cases. These
pollutants pose serious threat to environment and human health because of their toxicity,
persistence and bioaccumulation tendency. There are plenty of conventional methods for
heavy metal removal, but in most cases, they are too expensive for removing low, but still
toxic present concentrations, with high operational cost/energy demand, or they create large
quantities of toxic sludge which request further processing. The application of low cost,
mostly waste materials as a heavy metal sorbent are a potential alternative to the existing
conventional technologies for the removal/recovery of metal ions from aqueous solutions.
The major advantages of sorption by renewable biomass over conventional treatment
methods include low cost and abundance of biomaterials, high efficiency with minimum
sorbent treatments, minimization of sludge generation and feasible regeneration with
possibility of metal recovery. At the same time, application of renewable waste materials
contributes to carbon sequestering and climate change mitigations, avoiding land usage and
negative impact of landfilled material onto environment. The revalorization of this kind of
sorbents also contributes to resource conservation and circular economy in its broadest
sense. In this research, lignocellulosic waste material from food industry (sour cherry
stones) has been applied as a sorbent for treatment of polluted water with various heavy
metals. The sour cherry stones are widespread, locally available waste with considerable
potential for sorbents development. This lignocellulosic material was grinded into particle
size of approximately 0.5 mm, marked as CSP, and investigated for removal of heavy metal
content in contaminated water containing highly toxic metals: Cd2+, Cu2+, Ni2+, Zn2+, and
Pb2+. Sorption experiments were performed in an isothermal batch system with stirring
under specified operational conditions, avoiding metal precipitation. The removal
efficiency of investigated metals reduced in order Pb2+ > Cd2+ > Cu2+ > Zn2+ > Ni2+ using
CSP as a sorbent. The CSP characterisation included: contact pH (pHsus), point of zero
charge (pHpzc), Scanning Electron Microscopy (SEM) and energy-dispersive X-ray
spectroscopy (EDX). Structural characterization of the CSP surface was performed using
Fourier transform infrared spectroscopy (FTIR), which disclosed the presence of specific
functional groups (hydroxyl, carbonyl and carboxyl) responsible for the removal of heavy
metals ions. The obtained results suggest that the application of the raw CSP is an
economic and environment feasible strategy for removing heavy metals from water polluted
streams.

AB  - Current demand on adsorbent materials is in constant growth, hence scientific society is in ceaseless
research subjecting cheap and optimal adsorbent. Abundant raw materials which may be utilized as
adsorbent of cation species are mica minerals, and vermiculite as one of them is widely examined.
Since wastewater may contain anion or/ and non-ionic pollutants it is needed to functionalize
adsorbent so it may attract those species as well. Goethite and ferrihydrite are potential candidates
for such modification since they: have large specific surface area (SSA), possess hydroxide group
and they are not toxic to the environment. Goethite/ expanded vermiculite (Goe/EV) and ferrihydrite/
expanded vermiculite (Fer/EV) are successfully prepared and those composites have showed better
adsorption related chemical properties than expanded vermiculite (EV) itself. Utilizing BET
methodology, it is determined that Fer/EV possess five-time larger SSA than EV, while Goe/EV is
two times larger. Measuring cation exchange capacity (CEC) it is determined that modified samples
have only ~10% smaller values of CEC. Summary, both composites have shown higher affinity
toward cationic dye, malachite green and also showed their adsorbent potential toward anionic dye,
tartrazine. Thanks to facile preparation of such materials and its cost, it may be concluded that they
are prospective choice as adsorbents, in first order of heavy metals and dyes.

AB  - Adsorbenti na bazi oksida Fe3+ i Cr3+predmet su brojnih istraživanja. Interkalacioni sloj
vermikulita koristan je medijm za taloženje nanočestica. Zbog svoje relativno velike površine,
kapaciteta katjonske izmene i prirodnog obilja vermikulita, ovaj liskunski mineral i njegovi kompoziti
mogu biti valorizovani kao potencijalni adsorbenti. U ovoj studiji kompozit oksida
Fe3+/Cr3+/ekspandirani vermikulit (Fe2O3 / Cr2O3 / EV) pripremljen je metodom in-situ. Kompozitni
i osnovni materijal karakterisan je Furijeovom transformacijom infracrvene spektroskopije (FTIR),
rendgenskom difrakcijom (XRD), skenirajućom elektronskom mikroskopijom (SEM), a određeni su i:
specifična površina BET-om (SBET), kapacitet katjonske izmene (CEC) i pH tačke nultog
naelektrisanja (pHPZC). Adsorpciona svojstva Fe2O3 / Cr2O3 / EV i EV ispitivana su u šaržnom
sistemu na pH blizu pHPZC za uklanjanje Ni (II) iz vode. Uzimajući u obzir parametre procesa kao
što su vreme kontakta, masa adsorbenta i temperatura određeni su tip adsorpcije, termodinamički i
izotermski parametri (Lengmir i Frojndlih) i parametri brzine adsorpcije. Rezultati kinetičkih studija
dali su dobre korelacije sa modelom pseudo - drugog reda i Veber - Morisovim modelom. Uzimajući
u obzir činjenicu da je EV imao niske vrednosti CEC i specifične površine, dobijeni kompozit ima
umerenu adsorpcionu sposobnost (22,9 mg/g).

abstract = "Adsorbenti na bazi oksida Fe3+ i Cr3+predmet su brojnih istraživanja. Interkalacioni sloj
vermikulita koristan je medijm za taloženje nanočestica. Zbog svoje relativno velike površine,
kapaciteta katjonske izmene i prirodnog obilja vermikulita, ovaj liskunski mineral i njegovi kompoziti
mogu biti valorizovani kao potencijalni adsorbenti. U ovoj studiji kompozit oksida
Fe3+/Cr3+/ekspandirani vermikulit (Fe2O3 / Cr2O3 / EV) pripremljen je metodom in-situ. Kompozitni
i osnovni materijal karakterisan je Furijeovom transformacijom infracrvene spektroskopije (FTIR),
rendgenskom difrakcijom (XRD), skenirajućom elektronskom mikroskopijom (SEM), a određeni su i:
specifična površina BET-om (SBET), kapacitet katjonske izmene (CEC) i pH tačke nultog
naelektrisanja (pHPZC). Adsorpciona svojstva Fe2O3 / Cr2O3 / EV i EV ispitivana su u šaržnom
sistemu na pH blizu pHPZC za uklanjanje Ni (II) iz vode. Uzimajući u obzir parametre procesa kao
što su vreme kontakta, masa adsorbenta i temperatura određeni su tip adsorpcije, termodinamički i
izotermski parametri (Lengmir i Frojndlih) i parametri brzine adsorpcije. Rezultati kinetičkih studija
dali su dobre korelacije sa modelom pseudo - drugog reda i Veber - Morisovim modelom. Uzimajući
u obzir činjenicu da je EV imao niske vrednosti CEC i specifične površine, dobijeni kompozit ima
umerenu adsorpcionu sposobnost (22,9 mg/g).",

AB  - Lignocellulosic waste biomass (LCW) certainly represents a part of the solutions to the lowcarbon
future. LCW could serve as a base for a variety of sustainable fuels and bio based
materials, whose proper implementation could help in economic and environmental growing
world demands. Fruit stones, wastes from food processing industries, are contributing toward
negative effects on the environment systems through the impacts associated with both waste
production and its disposal. This waste type can be converted into value-added products
using thermochemical methods, such as pyrolysis, where the biomass is efficiently converted
into biofuels, biochars and different value added products. In this paper, two LCW materials,
peach (PS) and cherry stones (CS) and their derived biochars (PS-B and CS-B), have been
successfully applied for the removal of the hazardous water-soluble cationic dye, brilliant
green (BG). Functional groups present in LCWs and related biochars were analysed using
Fourier transform infra-red (FTIR) technique. Bio based sorbents were also characterized by
determination of pHsus and pHpzc. The pristine LCWs, PS and CS, were first milled to
desired dimensions, washed and dried at 60 oC. Pyrolysed samples, PS-B and PS-C, were
obtained by heating in oxygen limited conditions from 25 to 500 оС (10 оС/min heat flow),
and kept at 500 °C for 2 h. The contact pH (pHsus) as well as pHpzc were higher in both
cases for the biochar samples, indicating higher –OH content (confirmed also by FTIR
analysis) and favourable surface for cationic sorbate types. The experimental sorption results
indicated that biochars have almost two times higher sorption capacities than the native
materials, under the same operational conditions, while the highest binding was achieved by
cherry stone biochar, 135.3 mg/g (experimental data modelled by Sips isotherm).
Conclusively, the LCWs derived biochars can be efficiently used as an alternative to
conventional sorbents in contaminated water treatment.

AB  - Adsorbents based on magnetic materials are the subject of numerous researches. Beside good magnetism and functional surface, manganese ferrite is unstable and prone to form low mechanical strength agglomerates, which necessitate its deposition on the substrate surface. Expanded vermiculite outer surfac, is a useful medium for the deposition of nanoparticles whereas intercation layer is suitable for holding cation species (distance of 2:1 layers may be greater than 10 Å). Due to its relatively high surface area, cation exchange capacity and natural abundance of vermiculite, this mica mineral and its composites could be valorized as potentially low-cost adsorbents. In this study, manganese ferrite/expanded vermiculite (MnFe2O4/EV) composite was prepared by in-situ method. Deposited manganese ferrite particles on the surface of EV were formed in the solvothermal reaction using suitable reagents. Both composite and base material are characterized by Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) specific surface area (SSA), cation exchange capacity (CEC) and pH point of zero charge (pHPZC) determination. The adsorption properties of MnFe2O4/EV and EV have been investigated in a batch system at pH close to the pHPZC for the removal of Ni (II) from water. Considering process parameters such as contact time, adsorbent dosage and temperature: adsorption type, isotherm parameters (Langmuir and Freundlich) and rate of adsorption parameters were determined. Results of the kinetic studies gave fine correlations with pseudo – second order and Weber – Morris model. Taking into consideration fact that EV had low CEC values and SSA, obtained composite have high adsorption capacity (more than 30 mg Ni g-1). Also, X-ray diffractograms showed alteration of biotite vermiculite (formed during solvothermal action) into phlogopite (formed after adsorption process and aging). The methodology applied in this work may be utilized for the fabrication of other ferrite spinels, perovskites and other oxide systems.

AB  - Expanded vermiculite (EV) was modified by deposition of different spinel ferrite composites on the outer surface of EV 2:1 layers in order to improve its adsorptive properties. Modifications were made by deposition of: magnetite, manganese ferrite, cobalt ferrite and chromium oxide/hematite. The characterization of modified materials was performed by: scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) methodology, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), magnetization measurements, as well as determination of cation exchange capacity (CEC) and pH point of zero charge (pHPZC). Obtained samples were used as adsorbents for Pb2+, Ni(2+)and Cd2+ ions from an aqueous solution in a batch system. Results showed that adsorption capacity was strongly dependent on physical and chemical changes induced by specific chemical modification. Hydrothermally produced manganese and cobalt ferrites caused significant surface changes and altered the interlayer cation balance. Among the others, EV-Mn/Co-ferrite(s) samples possessed the highest adsorption capacity towards Ni2+ (33.06 mg g(-1)), along with an increase of the CEC. Freundlich's adsorption isotherm model provided the best fit of obtained experimental data, while kinetic studies showed that the adsorption rate follows the pseudo second-order model, implying heterogeneous adsorbents surface. Thermodynamic and kinetic parameters indicated that the mechanism of cations removal efficacy was dominantly followed by the ion exchange. This study confirmed that doped ferrites, produced by solvothermal method, improve surface properties of EV and increase adsorption potentials towards heavy metals.

AB  - Fluoride ions (F-)might be found in drinking or wastewaters in too high concentrations either due to the
anthropogenic activity or some natural sources. Due to their negative effects on human health, allowed concentrations
for F- content in drinking water have been decreased. Therefore, in the last decade, investigations into researches in
new materials/techniques for fluoride removal from water streams have been intensified. This paper examines the
potential of hydroxyapatite loaded aluminum gelled alginate particles as an efficient and cheap sorbent 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 concentration of adsorbate. Obtained results indicate
good adsorption capacity and removal efficiency, while FTIR spectra analysis point to the increased stability of
investigated adsorbent compared to Al-alginate without HAP.

physical structure but becomes far more porous than vermiculite which is
accredited to the huge increase in the intercalation layer thickness. This feature in
conjunction with the fact that the intercalation layer enriched by intercalation cations
and water was the initial motive for this research, which opened a novel method
for spinels synthesis. Intercalation layer of the EV is utilized as a reaction medium
for the synthesis of Fe3O4, MnFe2O4, CoFe2O4, and FeCrFeO4. While magnetite
is synthesized using the co-precipitation method, others are synthesized using
hydrothermal co-precipitation method. Composites are then characterized by XRD
(X-ray diffraction), FTIR (Fourier transformed infrared spectroscopy), SEM/EDS
(scanning electron microscopy with energy dispersing microscopy) that confirmed
the presence of the ferrite spinels inside the intercalation layer. After performed
synthesis of the spinels, further parameters were determined: the isoelectric point
(IEP), the capacity of cation exchange (CEC) and specific surface area (SSA) is
calculated using Brunauer–Emmett–Teller (BET) adsorption isotherm of each
composite together with matrix material (EV). The composites could be used as
potential adsorbents of heavy metals and/or organic pollutants, and this synthesis
method could be used for producing numerous compounds that are mainly being
produced by solvothermal method or co-precipitation method.

AB  - Point of zero charge (PZC) is one the most valuable parameter of adsorbent preparation process, in
wastewater management. Although, this parameter may be determined measuring the electrokinetic potential (zetta
potential) as the function of pH; material engineers oftenrely on pH PZC value which may be easily determined and
can give usefuladsorbent properties duringexploitation. Samples from previous study are characterized and their pH
PZC values are determined. Provided results are such intriguing since they brought conclusions that those values can
be explained by process parameters of the particular sample preparation. Sample marked as Cr2O3/Fe3O4/EVer have
lowest pH PZC value (4.75) and sample marked as MnFe2O4/EVer highest pH PZC value (7.47). Another study in this
paper showed that pH PZC value could be easily increased or decreased by simple base or acid treatment, respectfully.
As expected, samples treated with bases or prepared in alkali medium have greater adsorption capacity towards
cation species, up to 20 % more than base material in the case MnFe2O4/EVer.

AB  - Finding the raw material which can be used as adsorbent of heavy metals from water solution without any modification would be beneficial for solving the capital issue of water pollution. Heavy metal water pollution is a problem of almost every single country, so in the near future huge amounts of adsorbents would be needed to reduce the level of water pollutants. Considering this fact it is necessary to find available, abundant and cheap raw material which can be utilized as adsorbent as is or with minor processing. A plenty of mineral raw material fulfil all requirements of the potential cheap adsorbent. Aim of this paper is to determine potential of volcanic rock found in Etna valley as an adsorbent of heavy metals in anionic form (chromates, arsenates and selenates). Characterization of the volcanic rock was done with chetnical methods (AAS, AES, gravimetric analysis, XRF) and physicochetnical methods (XRD, FTIR, SEM). Also maximal adsorption capacity was determined. All the results of adsorption capacity were satisfying considering the mineral composition, granulation and porosity.

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  - 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.
