AB  - The minerals with unique properties such as mica minerals have promising approach in
environmental and industrial sphere. In this study, cobalt ferrite/expanded vermiculite (CoFe2O4/EV)
composite was prepared by in-situ method. Both composite and base materials are characterized by FTIR,
XRD and SEM techniques, while the CEC and point of zero charge (pHPZC) was also determined. The
adsorption properties of CoFe2O4/EV and EV have been investigated in a batch system, for the Ni (II)
sorption from water. Adsorption experimental results were fitted by kinetic and adsorption models, and
resulted in ionic exchange mechanism with maximum adsorption capacity of 23.2mg g-1 (298 K).

AB  - Mushrooms are widely investigated and recognized as perspective materials for the removal
of various pollutants from wastewater effluents. In this study, mosaic puffball Handkea
utriformis was tested as a new biodegradable, but relatively stable material for Cd2+
adsorption from aqueous mediums. The fruiting body of Handkea utriformis goes through the
process of autodigestion, during which their inside – gleba is turned into a powdery, sporebearing
mass, and the lower portion of the fruiting body – subgleba, into a dark, dry, spongy
mass. The impurities and spores present on the surface of the subgleba can be removed in a
simple process of purification with acidic and alkaline solutions. The purification decreases
the hydrophobicity of the surface of this material, and therefore increases the number of
surface functionalities, knowing that subgleba consists of sugars, proteins and polymeric
pigments (melanins). The subgleba purified with 0.1M HCl and 0.1M NaOH (Sp) was used
for the removal of Cd2+ from the aqueous solution. The efficiency of the material for
adsorption of Cd2+ was investigated in a batch system under the constant initial concentration
of adsorbate and pH and different concentrations of the adsorbent. Composition and surface
morphology were characterized by using FT-IR spectroscopy, SEM and EDX analysis.
Concentrations of Cd2+, before and after adsorption, were determined by using Atomic
Absorption Spectroscopy (AAS). The Langmuir and Freundlich isotherm models, as well as
kinetic models, were evaluated to correlate experimental data. The results showed that kinetic
data were well fitted by a pseudo-second-order model. Isotherms studies revealed that the
best fit was achieved with the Langmuir isotherm model with a maximum adsorption capacity
of 15.2, 19.1 and 25.0 mg g-1 at 25, 35 and 45ºC, respectively.

AB  - Silanization of the natural and synthetic zeolites as well as their use as adsorbents for removing arsenic(III) oxyanions from wastewater are the topic of this paper. Two types of zeolite were used: natural zeolite-clinoptilolite from Zlatokop deposit, Vranjska Banja, Serbia,
previously converted to H + -form and synthetic zeolite, mordenite. The modification was
performed with solution (3-aminopropyl) triethoxysilane (APTES). The presence of APTES
on the surface of zeolite was confirmed using TG/DSC and FTIR analysis. The results showed
that natural aminosilane-modified zeolite has a higher adsorption capacity for arsenic(III)
oxyanions compared to mordenite prepared in the same way. The kinetic data follow the
Lagergren pseudo-second-order model. This model implies a chemical interaction between
As 3+ - ions and functional groups on the silanized zeolite surface.

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  - 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  - Expanded vermiculite (EV) is clay, a typical 2:1 phyllosilicate which may be
easily produced from the mineral vermiculite. After expansion EV withholds vermiculites
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  - The industries of leather-tanning, mining and textile dyeing, generate large amounts of
chromium-containing wastewater. Hexavalent Cr(VI) is highly poisonous and extremely
mobile in the surface-water and groundwater in a broad pH range and therefore it has
been identified as a potentially carcinogenic substance. The aim of the presented work
was to develop cellulose-based membrane functionalized with magnetite, which could
be used as an efficient adsorbent for the removal of hexavalent chromium Cr(VI) ions
from aqueous solutions. Cellulose-based filter (CF) was functionalized with magnetite
in three-step process. In the first and second step CF surface was modified using
an ethanolic solution of (3-aminopropyl)triethoxysilane (APTES), and
diethylenetriaminepentaacetic acid dianhydride, respectively. The introduction of amino
and carboxylic groups provided successful precipitation of magnetite in the third step.
The obtained cellulose-magnetite membrane (CelMag-M) was characterized by FTIR
and SEM analysis. Adsorption of Cr(VI) onto CelMag-M was studied using batchadsorption
test. Under optimum pH conditions, the maximum experimental adsorption
capacity of CelMag-M for Cr(VI) was found to be 111.2 mg g–1. The adsorption process
was endothermic, the equilibrium adsorption data could be best fitted to the Langmuir
adsorption isotherm model and kinetics was in agreement with the pseudo-second-order
rate equation.

test. Under optimum pH conditions, the maximum experimental adsorption
capacity of CelMag-M for Cr(VI) was found to be 111.2 mg g–1. The adsorption process
was endothermic, the equilibrium adsorption data could be best fitted to the Langmuir
adsorption isotherm model and kinetics was in agreement with the pseudo-second-order
rate equation.",

AB  - Heavy metal presence in aquatic ecosystems has a huge impact on almost all the living [1]. Problem such as this have to be lessened or eliminated if it is possible. Facile and efficient method for decreasing pollutant concentration from water solutions is by adsorption [2]. In this work raw expanded vermiculite (REV) is utilized as carrier of magnetite microcrystals. This modification of the REV was done by ultrasound and consecutive precipitation of magnetite particles on its surface. This composite is characterized using further methods: X–Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transformed Infra-Red (FTIR), specific surface area (using BET methodology) and Cation Exchange Capacity(CEC) and its adsorption properties are checked. Considering the structure, CEC and specific surface area this material has moderate adsorption parameters. For example, batch adsorption on 35 °C adsorbent accomplished capacity of 19 mg Ni/g and 65.8 % removal of Ni for 90 minutes of adsorption is done on 45 °C are done with S/L ratio of 1,33 g/L. Adsorption kinetics followed pseudo–second order, as exceptedwith equilibrium capacity of 14.27 mg Ni/g and rate constant of sorption of 0.00594 g/(mg min). Isotherm showed the best correlation with Freundlich isotherm model and somewhat poor for Langmuir isotherm. Gibbs free energy decreases with temperature increase showed that the adsorption process is endothermic so chemisorption is the mechanism responsible for nickel removal.
