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  - Hydrothermal carbonization (HTC) was employed for the conversion of the spent mushroom substrate (SMS) into a carbonaceous hydrochar. The effect of operating temperature (180, 200, 220, 240, and 260 ?C) on the physicochemical, structural, and combustion properties of the obtained hydrochars was analyzed. The HTC treatment caused the increase of the higher heating value (HHV) and the lower heating value (LHV) of hydrochars for 58 % and 65 % in comparison with SMS, respectively. Analysis of morphology and functional groups showed the formation of microspheres and cracks on the hydrochar surface, which are predominantly dominated by aromatic and oxygen-rich functional groups. Thermal and kinetics analysis showed that HTC treatment improves the combustion behavior of the obtained solids. Combustion kinetic parameters of SMS and hydrochars were determined by the methods of Kissenger-Akahira-Sunose (KAS) and Flynn-Wall-Ozawa (FWO). The thermodynamic parameters and pre-exponential factors reveal a complex mechanism of SMS and hydrochars decomposition process.

AB  - The lack of clean water and waste generation are problems that exist in many parts all over the world. Different industries: electroplating, smelting and alloying could discharge cadmium pollutants into water body. Cadmium as toxic metal must be properly removed from wastewaters because it may lead to: kidney damage, respiratory insufficiency, hypertension, cancer, gastrointestinal disorder and osteoporosis.

Globally depletion of natural and nonrenewable resources has induced need for application of renewable sources in environment protection practices; such as renewable biomass. Biosorption has emerged as an economically feasible alternative for the environment cleanup using naturally occurring, abundant, waste biomass. Application of biosorbents in the form of powder have difficulties associated with their powder properties, indicating need for suitable form with adequate mechanical strength (e.g. beads) for easily manipulation and further use in flow systems.

The waste biomass which is tested as biosorbent of cadmium is cosmopolitan invasive aquatic weed - waste Myriophyllum spicatum immobilized as beads in natural polymer matrix-alginate – (MsA-B). M.spicatum grows on five continents and based on its widely negative effects on the environment in the whole world, this weed has been categorized as Category 1 Weed. M.spicatum used for preparation of beads originates from Sava Lake (Belgrade, Serbia) where it is regularly harvested by public company "Ada Ciganlija”. Ratio M. spicatum and alginate in beads is 2:1.

This biosorbent (MsA-B) was characterized by Scanning-Electron-Microscopy-EnergyDispersive-X-Ray-Spectroscopy (SEM-EDX). EDX spectra showed: Ca, Mg, Na, K and Cl. Large amount of calcium originate from the water environment in which this aquatic weed lives. The surface of (MsA-B) is different from the surface of aquatic weed because the alginate covered the characteristic rectangular openings. The beads are not spherical, but more ovoid shape. The surface is wrinkled and clearly layered. After Cd(II) sorption, reduced peaks of Ca as well as a new peak of Cd(II) are observed

The effect of the Cd(II) concentration on adsorption was studied at pH 5.0 in the concentration range from 20 to 750 mg/L as batch biosorption tests with 2 g/L MsA-B. Experimental results were fitted by six isotherm models: Langmuir, Freundlich, Sips, Redlich and Peterson, Toth, Temkin. After biosorption experiments, beads didn’t change its shape, size or colour. They have been easily separated from the solution by decanting. Comparison of models was made on the basis of the coefficients of determination R2 and comparison value of biosorption capacities experimented and calculated by models. Order of best fit isotherm models: RP>L>S>Th>T>F. MsA-B showed high capacity for Cd(II) removal q=82,5 mg/g which is 33% higher capacity then capacity of dry biomass M.spicatum. During the biosorption experiments with MsA-B, changes of pH were insignificant. That is very important because there is no need to control pH, no demand for chemicals which greatly simplifies the process and makes it cheaper. Easy application and manipulation, much easier than other biosorbents simplify further investigations and applications of this aquatic weed beads – MsA-B in industrial wastewaters and also in the next step of the biosorption processes: flow systems and reactors.

AB  - The investigations in scope of this doctoral dissertation were based on the content of a several phytochemicals and it comprised chemical characterization of kernels of 25 peach cultivars/genotypes differing in genetic and geographical origin cultivated under the same climatic conditions in the territory of Serbia within a collection of the „Radmilovac‖ Experimental Station of the University of Belgrade - Faculty of Agriculture. In order to determine the similarities and differences between the individual cultivars/genotypes of the peach, as well as to identify potential biomarkers of their genetic and geographical origin, the research included an analysis of the variability of standard cultivars (originating in the USA and Italy), promising hybrids (created by standard cultivars cross-breeding) and several vineyard peach genotypes as autochthonous cultivars from Serbia. Except from this division, the examined genotypes of the peach differed according to the ripening time. Gas chromatography with flame ionization detector (GC-FID) was used to determine the composition of fatty acids in samples of the peach kernels. Regardless of the difference between genotypes, the peach kernel oil has the similar fatty acid composition, which the most consists of unsaturated fatty acids, oleic and linoleic acids. Variation between varieties/genotypes of peach is only seen in the difference in the percentage concentrations of the most abundant fatty acids. The kernel oil has a low total saturated fatty acid content less than 15%, which is mainly composed of palmitic and stearic acids. The phenolic profile of peach kernels was determined by ultra-high-perfomance liquid chromatography coupled with a hybrid mass spectrometer (UHPLC-LTQ OrbiTrap MS/MS). In samples of peach kernels, different classes of phenolic substances and several organic acids with small number of C atoms were detected. Among phenolic compounds, the most abundant in peach seeds were catechin and six phenolic acids: protocatechuic, p-hydroxybenzoic, p-hydroxyphenylacetic, chlorogenic, p-coumaric and ferulic acids. The quantification of saccharides was perfomed using high-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD)...

AB  - The apricot stones (KK) were investigated as biosorbent of copper ions from aqueous
solution. The rigidity of lignocellulosic compact molecular arrangement, induce the necessity of its
modification. The aim of this paper was to establish optimal parameters of KK modification in order
to improve low-cost biosorbent with improved biosorption characteristics. The modification
parameters were: initial NaOH concentration, contact time and biomass/base solution ratio. After
sets of experiments, the optimal modification parameters for copper removal were found to be:
initial concentration of modification agent 1.0 mol/L NaOH, solid/liquid ratio 1:20 and 180 minute
of contact time.
The results show that modified apricot shells doubled the binding affinity toward copper ions, and
could be used as an efficient low-cost biosorbent, promoting more sustainable production and to
stop waste disposal at landfill sites.

AB  - Manganese occurs naturally in surface and groundwater due to mineral dissolution
and leaching process, but also as a result of human activities such as manganese
ore mining and processing, different alloys and salts production. It is also used as a gasoline
additive, a component in ceramic/glass manufacturing, some agrochemicals (fungicides and
fertilizers). Manganese is an essential element for the functioning of many enzymes and can
serve as an activator of many others, but manganese is not biodegradable, and its bioaccumulation
in living organisms can cause many diseases and disorders. In the present study,
the biosorption efficiency for the manganese ions from synthetic solution by raw and modified
apricot and peach shells has been investigated. These lignocellulosic materials were
obtained from local juice factory, where they have been discharged as the waste. Removal
of manganese ions was investigated using the following biosorbents: raw apricot shells (KK)
(particle size <0.65 mm), modified KK with mixture of 2% alginate and bentonite (KKAlB),
raw peach shells (particle size <100 μm) modified by: 2% alginate (KBAl), 2 mol/L HNO3
(KBM) and with the mixture of 10% FeCl3×6H2O and 0.1 mol/L KOH (KBFe). Experimental
biosorption parameters were: initial concentration of manganese ions: 35 mg/L; m/V ratio: 5
g/L; contact time: 24h and initial pH value of the solutions: 4.5. The results have shown that
KK is the most suitable and cost-effective biosorbent for the removal of manganese ions
from aqueous solution. As apricot shells are widely available in the Republic of Serbia as
food industry waste, application of this biosorbent can help in minimizing waste disposal and
in water treatment at the same time.

AB  - Increasing fossil fuel depletion that leads to air pollution and global warming have become serious environmental problem. For this reason, a numerous of alternative biofuels have been developed and investigated as potential energy sources to substitute them. One of promising and highly effective technology for conversion of wet and waste biomass into multi-functional materials is a hydrothermal carbonization. In this study grape pomace was hydrothermally carbonized at different temperatures (180, 200 and 220 °C). Produced hydrochars were characterized in order to investigate its potential application as an alternative and energy-efficient renewable fuels. The carbon, fixed carbon, sulphur and volatile matter contents were determined in all hydrochar samples. Obtained results showed that temperatures play significant role on the structural characteristics of produced materials. As expected, the carbon content and fixed carbon content in hydrochars were increased with temperature increasing. Higher yields of carbon and fixed carbon observed in hydrochars indicated that intensive carbonization of biomass occurred. On the contrary, sulphur and volatile matter content were decreased. Observed reduction may be a result of dehydration and decarboxylation of grape pomace during hydrothermal treatment. These reductions are highly beneficial and improve the efficiency of solids' direct combustion. Decreased volatile matter content can potentially reduce the release of inorganic vapours and pollutant emission during combustion, while decreased sulphur content preventing generation and emission of harmful sulphur oxides, SOx, compared to the parent biomass. The present study showed that hydrothermal carbonization mproved fuel qualities and potential of grape pomace hydrochars among different reaction temperatures.

AB  - In this study, the sorption capacity of Cd (II) removal from aqueous solution was investigated using
hydrochar obtained from substrate for cultivating mushrooms. In order to increase the adsorption
capacity, hydrochar was previously modified with 2M KOH. The obtained results showed that alkally
modification increased the sorption capacity from 41.5 mg/g to 53.5 mg/g. Structural
characterization of alkally modified and unmodified hydrochars were performed by Fourier transform
infrared spectroscopy (FTIR). According to obtained results of FTIR analysis, the increased of the
oxygen functional groups (OFG) in alkally modified hydrochars was observed, which is contributed to
the increase in the adsorption capacity of this hydrochar. Results indicated that substrate for

abstract = "In this study, the sorption capacity of Cd (II) removal from aqueous solution was investigated using
hydrochar obtained from substrate for cultivating mushrooms. In order to increase the adsorption
capacity, hydrochar was previously modified with 2M KOH. The obtained results showed that alkally
modification increased the sorption capacity from 41.5 mg/g to 53.5 mg/g. Structural
characterization of alkally modified and unmodified hydrochars were performed by Fourier transform
infrared spectroscopy (FTIR). According to obtained results of FTIR analysis, the increased of the
oxygen functional groups (OFG) in alkally modified hydrochars was observed, which is contributed to
the increase in the adsorption capacity of this hydrochar. Results indicated that substrate for
cultivating mushrooms can be converted into hydrochar as a sorbent for sorption of Cd (II), and the
presence of OFGs play important role in the hydrochar’s high adsorption capacity.",

AB  - Recently, there is a growing interest in the utilization of waste biomass to curb its potential negative impact on the environment, which includes CO2 emission and various types of soil pollution. Simultaneously, the development of thermochemical technolo gies for conversion of waste biomass into valuable materials becomes very attractive. Hydrothermal carbonization is proposed as a promising and highly effective technology in this field.
In this paper, grape pomace was hydrothermally carbonized at 220 and 240°C to explore the potential application of derived hydrochars (HC-220 and HC-240, respectively) for removal of Cd(II) and Al(III) from aqueous solutions. Obtained preliminary results showed that adsorption capacities achieved using the HC-220 were 65.25 mg/g for Cd(II) and 17.13 mg/g for Al(III). On the other hand, the HC-240 showed smaller capacities for both examined materials (24.25 mg/g for Cd(II) and 9.0 for Al(II)). Differences in the structural properties of hydrochars produced at different carboniza- tion temperatures could be a reason for this observation. Literature data states that higher temperature causes the formation of energy-dense coal-like hydrochars with dominant aromatic structure. Therefore, material obtained at 240°C had less functional
group on its surface and more aromatic structure compared to the HC-220, and thus
less electron donating sites for metal ions adsorption.
Results from this paper suggest that the grape pomace could be a promising precursor for the production of low-cost hydrochars for adsorption of Cd(II) and Al(III) from wastewaters. Besides, results can be further used for the optimization of the HTC
process parameters to find the most adequate reuse of the waste grape pomace.

AB  - Increasing fossil fuel depletion that leads to air pollution and global warming have become
serious environmental problem. For this reason, a numerous of alternative biofuels have been developed
and investigated as potential energy sources to substitute them. One of promising and
highly effective technology for conversion of wet and waste biomass into multi-functional materials
is a hydrothermal carbonization. In this study grape pomace was hydrothermally carbonized at different
temperatures (180, 200 and 220 °C). Produced hydrochars were characterized in order to
investigate its potential application as an alternative and energy-efficient renewable fuels. The carbon,
fixed carbon, sulphur and volatile matter contents were determined in all hydrochar samples.
Obtained results showed that temperatures play significant role on the structural characteristics of
produced materials. As expected, the carbon content and fixed carbon content in hydrochars were
increased with temperature increasing. Higher yields of carbon and fixed carbon observed in hydrochars
indicated that intensive carbonization of biomass occurred. On the contrary, sulphur and
volatile matter content were decreased. Observed reduction may be a result of dehydration and
decarboxylation of grape pomace during hydrothermal treatment. These reductions are highly beneficial
and improve the efficiency of solids’ direct combustion. Decreased volatile matter content
can potentially reduce the release of inorganic vapours and pollutant emission during combustion,
while decreased sulphur content preventing generation and emission of harmful sulphur oxides,
SOx, compared to the parent biomass. The present study showed that hydrothermal carbonization
mproved fuel qualities and potential of grape pomace hydrochars among different reaction temperatures.

AB  - The present work explored the effectiveness of Parsovići pyrophyllite ore as sorbent material for heavy metals such as Pb, Cu, Zn, Cd and Ni from aqueous solution. The analysis of chemical composition of PIR samples revealed the presence of silica and alumina besides Ca bearing phase; along with FTIR analysis which confirmed presence of hydroxyl groups attached to Si or Al, the composition of the ore sample indicates that this sample might be a prospective source for the effective metal sorbent. The preliminary batch sorption studies supported this hypothesis, indicating that the PIR sample poses highest affinity (mmol/g) in single ion solution towards Pb, followed by Zn, Cu, Ni and Cd. In multi metal solution the sorption of Zn was lowest. The sorption capacity under described operational conditions for Pb (single metal solution) was 47.25 mg/g.

AB  - In this paper, the character of structural changes induced by different mechanical treatments to Prunus persica stones (PSs), and its subsequent effect on biosorption kinetics of Cu(II) were investigated. PSs were processed in vibratory disk mill (PS-V) and ultra-centrifugal mill (PS-C) and characterized by XRD, BET, SEM and FTIR spectroscopy. It was shown that PS-V was smaller and more reactive with less crystallinity index and hydrogen bond intensity compared to PS-C. In opposite, surface area of the PS-C was bigger than that of the PS-V. The total pore volume was about threefold, while the volume of micro pores was 9.29 times higher in PS-Cs than in PS-Vs. The kinetics of Cu(II) biosorption by both PSs was tested through various kinetic models: pseudo-first and pseudo-second order rate equations, Elovich equation, Boyd model, Weber-Morris and Urano-Tachikawa intraparticle diffusion model. For both sample types, Cu(II) biosorption occurred through combination of intraparticle and film diffusion mechanism, while kinetic results were best described by the pseudo-second order kinetic model. At the same time, the results indicated that together with kinetic rate the biosorption capacity of PS-C (21.20 mg g(-1)) was higher than that of PS-V (16.30 mg g(-1)). Mechanical activation like crushing and grinding will change material particle size, specific surface area and porosity, as well as its crystallinity. However, this paper elucidates that such physical structural changes will impact on heavy metal ions removal efficiency. This investigation suggests that the type of size reduction in lignocellulosic biosorbent preparation plays a very important role in overall biosorption performance, so it should be carefully considered every time when the mechanical treatment of material is necessary to be applied.

AB  - Annual production of the sunflower seed in Serbia is between 650,000-720,000 tons. Most of this amount is used in vegetable oil industry. Abundant by-products from this processing are sunflower seed husks. Husks are usually incinerated by vegetable oil producers in order to obtain energy, used as an animal feed, or, unfortunately, landed up at some landfills. In order to promote new, added value for this abundant, renewable resource, the investigation presented in this paper was conducted. For that purpose, adsorption of Cu(II) ions from synthetic solution by unmodified sunflower seed husks was examined. ATR-FTIR was used to identify functional groups as potential active sites for Cu(II) sorption. Zeta potential values were determined to reveal the surface charge, while the cation exchange capacity (CEC) was determined to reveal the amount of exchangeable ions on its surface. ATR-FTIR analysis revealed the presence of specific functional groups (hydroxyl, carboxyl, carbonyl, and amine) responsible for removal of Cu(II) ions. The total CEC of sunflower husk is 47.74 meq/100g and Ca(II) and Mg(II) ions are in dominant exchangeable positions. The study of ion-exchange mechanism involvement was done and results confirmed that this mechanism is not the only mechanism which is involved in copper sorption. Also, the results show that the Cu(II) ions have preference for Mg(II) ions substitution. Sorption experiments were conducted in batch system. The effect of operating parameters (pH, contact time, initial concentration of Cu(II) ions and adsorbent dosage) on the adsorption capacity were investigated. The obtained experimental data were fitted by Langmuir and Freundlich isotherm models. The maximum adsorption capacity for Cu(II) ions calculated from Langmuir adsorption isotherm was 34.89 mg/g which is 15 to 35% higher than the capacity that other researchers reported previously for the same material and pollutant. These results are suggesting that sunflower seed husks have a potential to be applied as an effective adsorbent of copper ions from contaminated waters.
