AB  - Mushroom cultivation and consumption have been steadily increasing in recent decades, however, after mushroom cultivation, a large amount of by-products, known as spent mushroom substrate (SMS), are left behind in open dumps where about 5 kg of SMS are generated for every kilogram of mushroom (Agaricus bisporus). Around 51 million tons of SMS are produced in the world every year. Hydrothermal carbonization (HTC) is a promising technology for the conversion of SMS into a rich carbon product, hydrochar. The hydrochar was synthesized in a hydrothermal reactor at a temperature of 180 °C for a reaction time of 1 h. The characterization of the SMS and its chars was done by FTIR, SEM, and TGA analysis. The FTIR analysis showed that aromatic and oxygen-rich functional groups are dominant on the hydrochar surface. It was noticed that the hydrochar had more visible pores compared to the SMS. The porous structure and oxygen functional groups of hydrochar probably influenced the improvement of adsorption performance, since the adsorption capacity of SMS for Cd2+ ions was 28 mg L-1, while for hydrochar it was 92 mg L-1. On the other hand, the thermal kinetic analysis has shown that hydrothermally treatment upgrades the combustion behavior of hydrochar. The kinetic parameters were determined by Kissinger and Ozawa methods. The hydrochar had notably lower activation energy compared to the SMS, which means that this hydrochar requires a smaller amount of energy to start combustion. The preliminary results show that HTC effectively transforms SMS into alternative solid biofuel and eco-friendly sorbent.

AB  - In this study, the adsorption capacity of Pb2+ removal from aqueous solution was examined by hydrochar of the spent mushroom substrate. In order to improve the adsorption capacity, hydrochar was previously activated with 2M KOH. The obtained results demonstrated that alkally activation increased the sorption capacity from 36 mg g-1 to 74 mg g-1. Structural characterization of activated and inactivated hydrochars were performed by FTIR analysis. Toward to obtained results of FTIR analysis, the increased of the oxygen functional groups (OFG) in activated hydrochars was perceived, which is contributed to the increase in the adsorption capacity of this carbonized material. Results indicated that spent mushroom substrate can be converted into hydrochar as a perspective sorbent for removal of Pb2+.

AB  - Background: Over the years, the mass utilization of fossil fuels causes numerous harmful effects on the
environment. Therefore, great attention is paid to the implementation of technologies that would enable
the production of biofuels from renewable sources. Hydrothermal carbonization (HTC) is recognized as
one of the highly efficient and promising technologies for the production of value-added materials from
wet and waste biomass.
Objective: The main goal of this study is the valorization of waste grape pomace (GP) using HTC
technology. Emphasis will be placed on the examination of the influence of process temperature on the
selected structural and fuel characteristics of the obtained solids (hydrochars).
Methods: For the preparation of hydrochars 10g of GP and 150 mL of ultrapure water were carbonized
using laboratory autoclave (Carl Roth, Model II). Carbonization was carried out at 180, 200, 220, 240
and 260 °C within 1 h. Obtained hydrochars (H180, H200, H220, H240 and H260) were separated from
process water, rinsed and dried to constant weight. Elemental content of solid` (C, H, N, S) was performed
using Vario EL III; C, H, N, S/O Elemental Analyzer, while O contents and HHV were calculated.
Results: Obtained results showed that carbonization temperature significantly influences the structural
characteristics of produced hydrochars. The C content was increased from 48.9% (GP), up to 69.9%
(H260) with the temperature increase, while the content of other elements was decreased. Observed
changes in elemental composition are caused by dehydration and decarboxylation of biomass during the
HTC process. Additionally, the HHV of GP was 21.64 MJ/kg, while it was increased upon carbonization
up to 26.78 MJ/kg (H260).
Conclusion: Preliminary results of this study determined that implementation of HTC technology
improves fuel characteristics of GP and may represent a suitable route for the utilization of waste
biomass.

AB  - A calcium-pyro-hydrochar (Ca-PHC) can be distinguished as a novel sorbent of Pb2+ and Cd2+ from an aqueous solution. It was obtained using hydrothermal treatment of the spent mushroom substrate (SMS), followed by a CaCl2 center dot 5H(2)O activation and pyrolysis. The characterisation of chars before and after modifications was done by scanning electron microscope (SEM), Brunauer-Emmett- Teller (BET) and Fourier transform infrared (FTIR). Batch experiments were performed to examine Ca-PHC's sorption properties and binding mechanisms to selected metal ions. The maximum sorption capacities of Ca-PHC for Pb2+ and Cd2+ were 297 mg g(-1) , and 131 mg g(-1) respectively. The obtained results demonstrated that the sorption of Pb2+ and Cd2+ by Ca-PHC follows a pseudosecond kinetic model and Freundlich isotherm. The binding of the selected metals onto Ca-PHC was enabled by the ion-exchange mechanism, surface complexation, mineral precipitation and cation-pi interaction. Thermodynamic parameters indicate that metal ions binding by Ca-PHC are spontaneous and endothermic. Due to the high adsorption capacities, the obtained Ca-PHC has good potential for application in industrial wastewater treatment. In addition, the demonstrated use of SMS highlights another possibility of applying this specific biomass relevant to sustainable and economical waste management in the growing mushroom industry.

The obtained results demonstrated that the sorption of Pb2+ and Cd2+ by Ca-PHC follows a pseudosecond kinetic model and Freundlich isotherm. The binding of the selected metals onto Ca-PHC was enabled by the ion-exchange mechanism, surface complexation, mineral precipitation and cation-pi interaction. Thermodynamic parameters indicate that metal ions binding by Ca-PHC are spontaneous and endothermic. Due to the high adsorption capacities, the obtained Ca-PHC has good potential for application in industrial wastewater treatment. In addition, the demonstrated use of SMS highlights another possibility of applying this specific biomass relevant to sustainable and economical waste management in the growing mushroom industry.",

AB  - In this study, raw corn silk was considered for the removal of cadmium ions from aqueous solutions. In order to improve adsorption characteristics, the KOH treatment was applied as a route to obtain modified materials. Both materials before and after metal adsorption were characterized by pH(PZC), SEM-EDX and FTIR analysis. SEM images and FTIR spectra revealed that alkali modification caused some structural changes that could improve the adsorption properties of the investigated material. The experimental results and the ion-exchange study revealed that the biosorption process of cadmium ions on to raw and modified corn silk was caused predominantly by the ion-exchange mechanism, followed by chemisorption. The kinetic parameters implied that there are three stages in the biosorption process. In addition, the cadmium adsorption on both materials is very fast and is followed by the pseudo-second-order kinetic model. The experimental results were fitted by two and three parameter isotherm models, while the Sips isotherm model best describes the biosorption process on both materials. According to the Sips isotherm model, the maximum adsorption capacity of cadmium adsorbed on modified materials was 49.06 mg g(-1), which is 2.23 times greater in comparison to the raw material (21.96 mg g(-1)). Furthermore, the mechanisms of cadmium adsorption onto the investigated materials are summarized in order to better understand the modification influence on the adsorption properties of corn silk. In order to examine reusability of the investigated material, diluted nitric acid was used for regeneration. A desorption study was performed in three adsorption-desorption cycles. A high desorption efficiency (>85%) indicated that MCS after Cd adsorption can be efficiently recovered and reused for a new adsorption cycle.

AB  - A carbon-rich product, hydrochar, was synthesized by hydrothermal carbonization (HTC) of spent mushroom substrate (SMS), at temperature of 260 °C. The thermal kinetic analysis has shown that hydrothermally treatment improve the combustion behavior of hydrochar. The kinetic parameters were determined by Kissinger and Ozawa methods. The SMS-260 had a significantly lower activation energy compared to the SMS, which means that this hydrochar needs a smaller amount of energy to start combustion. Generally, the preliminary results show that HTC is an effective way to transform SMS into alternative solid biofuel.

In recent decades, the massive exploitation of fossil fuels, with a detrimental impact on the environment, caused a growing demand for the production of energies from renewable sources. One of the researchers' solutions was the application of waste biomass, but there are many disadvantages of its direct utilization, that include high moisture content, low energy content, high volatiles content, etc. In order to overcome these disadvantages, attention has been focused toward development of technologies for conversion of biomass into a multi-functional products. Hydrothermal carbonization (HTC) has recognized as highly effective technology for production of carbon rich material, hydrochar, from wet and waste biomass. Hydrochar possess a great potential for application as an energy source, for environmental protection, in agriculture. In this paper, three selected biomasses (corn cob (CC), Paulownia leafs (PL) and olive pomace (OP)) were hydrothermally carbonized at different temperatures (180, 220 and 260°C). The main goal of this study was to examine the influence of temperature on the structure and fuel characteristics of the obtained products and to compare it with the precursor. The results showed that the solid yiels decreases significantly with increasing temperature in all samples. On the other hand, C content increase upon temperature increment and reach the highest values in hydrochars obtained at 260°C (69.30% for CC, 64.54% for PL and 70.97% for OP). Also, a decrease in O/C and H/C atomic ratios with increasing temperature was observed. The results are shown in the Van Krevelen diagram, which reveals the transformation of precursors during carbonization from the biomass to the lignite region. Furthermore, with decrease of O/C and H/C ratio, higher heating value (HHV) was increasing and reaches the maximum values for hydrochars prepared at 260°C (27.33 MJ/kg for CC, 28.06 MJ/kg for PL and 30.55 MJ/kg for OP). The same trend is noticeable with ED contents. Also, the content of volatile matter (VM) was determined in all samples. VM decreases (from 90.45 to 55.42% for CC, from 76.70 to 62.10% for PL, from 82.86 to 66.77% for OP) with temperature contributes to less evaporation and pollutant emission during direct combustion. According to results, can be concluded that temperature has a great influence on the structure and characteristics of the obtained products, that dehydration and decarboxylation during HTC provoke intensive biomass carbonization and that hydrochars obtained at higher temperatures have significantly enhanced fuel properties and less volatiles compared to the biomass."

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  - In recent decades, massive exploitation of fossil fuels caused a growing demand for the production of energies from renewable sources. Hydrochar obtained from waste biomass via hydrothermal carbonization (HTC) possesses good potentials as a biofuel. Therefore, we performed HTC of corn cob, paulownia leaves, and olive pomace at different temperatures (180, 220, and 260 degrees C). The main goal of this study was to comparatively evaluate the influence of HTC conditions on the structure and fuel characteristics of the obtained solids. The results showed that the yields of hydrochar decrease significantly with increasing temperature in all samples. The carbon content and higher heating value increased and reached the highest values in hydrochars obtained at 260 degrees C, while the content of volatile matter decreased. Furthermore, the Van Krevelen diagram reveals that the transformation of feedstock to lignite-like products upon HTC was achieved. In this study, the results showed that processes of dehydration and decarboxylation during HTC provoke intensive biomass transformation and that hydrochars obtained at higher temperatures have significantly enhanced fuel properties and fewer volatiles compared to the feedstock.

AB  - U ovom istraživanju je korišćena hidročađ istrošenog supstrata gljiva radi ispitivanje njegove
potencijalne primene kao sorbenta, u cilju uklanjanja Pb2+ i Zn2+ iz vodenih rastvora.
Hidročađ je pripremana u hidrotermalnom reaktoru na temperaturi od 200 °C pri reakcionom
vremenu od 1 h. Strukturna analiza istrošenog supstrata gljiva i hidročađi vršena je pomoću
SEM analize, na osnovu koje je uočeno povećanje poroznosti materijala nakon hidrotermalne
karbonizacije. Takođe, povećanje adsorpcionog kapaciteta hidročađi u odnosu na istrošeni
supstrat gljiva se može direktno dovesti u vezu sa formiranjem pora na površini ugljeničnog
materijala.

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 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.

It is based on ability of biological materials to bind and to concentrate various pollutants from the aqueous solutions. Main advantages of biosorption process are efficiency, simplicity and availability of biomass. As bio-adsorbents many materials with biological origin have been investigated and their biosorption capacities have been reported in numerous research papers.

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  - The quality of life on Earth in the future will largely depend on the amount of safe water. Any use of water from numerous sources for different purposes, leads to negative changes in its physical, chemical and biological characteristics, resulting in the formation of wastewater in many forms, as industrial, communal, agricultural or rain. This type of water should be collected, and purified using efficient and economical cost-effective technology, or otherwise pose a serious environmental problem. In order to stop this trend, a large number of countries are undertaking extensive measures and invests large resources in order to stop water pollution and return pure, unpolluted water to nature. In this paper, possible biological procedures for purification of the Ada Huja Lagoon Belgrade, using microorganisms from the genus Bacillus, are presented. The Laguna Ada Huja is the recipient of all the listed types of wastewater and as such represents a serious environmental problem. The experiment was performed in laboratory controlled conditions using two different doses of microorganisms. Measurements of essential parameters (pH value, Ammonium ion, Nitrites, Nitrates, Consumption of KMnO4. Chemical consumption of oxygen, Biochemical consumption of oxygen (BPK), Total organic carbon (TOC)) were performed for 1, 15 and 60 days from wastewater treatment. It has been found that proposed technology, a mixture of heterotrophic, aerobic and optional anaerobic microorganisms produces extracellular enzymes for increased degradation of organic compounds in aforementioned environmental conditions. The use of these microorganisms leads to a decrease of the wastewater BOD/COD content, in addition, it reduces the amount of waste suspensions, reduces the filamentous bacterial reduction of the sludge population, and improves the characteristic of deposits, and therefore wastewater meets the regulated boundaries of the outflows and discharges into the watercourses.

AB  - Knowledge of the mobility of heavy metals and radionuclides, such as Pb, Cd, Zn and U, represents one of the goals of protection, regulation, rational use and irrigation of agricultural soils from the aspect of safe food production. The aim of this work was investigation of efficiency of natural mineral materials based on zeolite and apatite from domestic deposits in the mobility of heavy metals and radionuclides in the waters and soils of the different physico-chemical characteristics (pseudogley and chemozem). The affinity, efficiency, zeolite adsorption mechanisms and apatite adsorption precipitation were determined in a constant- pressure column system at 300 mg 1 for different pH values (5.00 and 7.00) of the basic contaminated solution (Pb, Cd, Zn, U) at time intervals of 30, 60, 90, 120, 180 minutes. In all experiments, significant changes in the pH of the filtrate occurred. The most significant changes in the pH of the filtrate, minimal fluctuations in the time interval, at pH = 5.00, recorded the basic solutions of Pb (7.69-7.87) and U (7.77-7.93) during leakage through the column with apatite, while slightly lower changes for Cd and Zn were observed. Changes also occurred in the column with the zeolite, but with a much lower intensity compared to the column of apatite, and with the trend of changes U> Pb Cd Zn. The trend of changes between apatite and zeolite also occurred in the basic contaminated solution with initial pH-7.00. Zeolite and apatite adsorption/precipitation processes successfully immobilized Pb at both tested pH values of stock solution. Our investigation showed that in colonies, apatite better immobilized U, zeolite is better for immobilization of the Cd, while for the Zn both materials showed a very similar affinity. Zeolite and apatite were added in amount of 20 gkg soil to reduce the content of water-soluble and easily accessible forms of Pb, Cd and Zn in uncontaminated and contaminated soil.

AB  - Adsorbents prepared from agricultural and industrial biowaste are being investigated as efficient
material for removal of various pollutants from wastewater. In this study, Paulownia leaves powder
and its hydrochar prepared from hydrothermal carbonization at 200°C was investigated as potential
adsorbents for Pb2+ ions from aqueous solution. Paulownia leaves and hydrochar at 200°C were
characterized by FTIR spectroscopy before and after adsorption of Pb2+ ions. The experimental
results showed that Paulownia leaves had better adsorption capacity (q=34.53 mg/g) than hydrochar
produced at 200°C (q=11.26 mg/g) and could be considered as effective biosorbent for Pb2+ removal
from wastewaters.

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 alternative and energy-efficient
renewable fuels. The carbon, fixed carbon, sulfur 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 (Table 1). Higher
yields of carbon and fixed carbon observed in hydrochars indicated that intensive carbonization
of biomass occurred. On the contrary, sulfur 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 vapors and pollutant emission during combustion, while decreased sulfur content
preventing generation and emission of harmful sulfur oxides, SOx, compared to the parent
biomass. The present study showed that hydrothermal carbonization improved 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
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  - In this study corn cob hydrochar was investigated as potential material for
the biosorption process. The corn cob hydrochar obtained at different carbonization
temperatures (180, 200 and 220°C) were examined as potential adsorbent of Mn2+
from aqueous solution.
The adsorption capacity of corn cob hydrochar obtained at different carbonization
temperatures followed the decreasing order: 220°C > 200°C > 180°C
To enhance adsorption potential, hydrochar with best adsorption abilities obtained
at 220°C (HC) was subjected to cold alkaline modification. The modified
corn cob (M-HC) was prepared through a chemical treatment process using 2M
KOH solution. Preliminary results showed that the M-HC exhibited excellent adsorption
characteristics for Mn2+ removal from aqueous solution. The maximum
adsorption capacity (qmax) of M-HC and HC was 31.83 and 7.83 mg/g, respectively.
It can be concluded that modified corn cob hydrochar can be used as a lowcost,
eco-friendly and promising adsorbent with a good adsorption capacity for Mn
ions removal from aqueous solutions.

AB  - U ovom istraživanju, korišćena je hidročađ supstrata za gajenje gljiva radi ispitivanja mogućnosti njegove primene kao adsorbenta za uklanjanje Cu2+ iz vodenih rastvora. Hidročađ je pripremana procesom hidrotermalne karbonizacije na temperaturi od 180 °C pri reakcionom vremenu od 1h. Strukturna analiza hidročađi vršena je pomoću FTIR-a. Analizom je potvrđeno smanjenje intenziteta kiseoničnih funkcionalnih grupa (KFG) usled adsorpcije Cu2+ što ukazuje da su ove grupe odgovorne za uklanjanje ispitivanog metala iz vodenog rastvora. Vrednost adsorpcionog kapaciteta iznosila je 37.5 mg/g. Dobijeni rezultati pokazuju da se ovaj materijal može koristiti kao efikasan adsorbent bakra.
