AB  - Environmental management demands innovative techniques for its protection and
treatment. The essential agreement of the modern world is to overcome every issue in a
sustainable way. The two major financial problems in this area are water pollution and
material corrosion. Persistent, organic compounds such as pesticides have devastating effects
on the water ecosystem. This problem can be solved by applying advanced treatment processes
(ATPs) like membrane separation and photocatalysis. Additionally, the corrosion of metal
materials needs to be prevented to preserve natural resources and reduce environmental
concerns. Therefore, researchers are trying to develop tunable, multifunctional materials
with broad applications. Employed materials in these operations must fulfill high criteria, like
durability, stability, and chemical and optical activity, to make specified processes efficient
and viable. Electroconductive polymers (ECPs) can meet the aforementioned standards. The
most used ECP is polyaniline (PANI), due to its catalytic and electrochemical performances.
These two properties are beneficial for both water purification and anticorrosion applications.
The objectives of the paper are to represent various PANI-based composites utilized in the
removal of different classes of pesticides during wastewater treatment by adsorption or
photocatalytic degradation. Further corrosion inhibition, utilizing PANI-based inhibitors, will
be discussed as well.

AB  - In the proposed study, agro-waste biomass oat straw (OS) was considered a potential adsorbent for Cu(II), Zn(II), and Se(IV) removal from aqueous solutions. In order to obtain material with better adsorption abilities, the OS was modified by a deep eutectic solvent (DES). Structural changes caused by the applied modification route were considered by pHpzc, SEM, FTIR, and DSC/TG analysis. These methods discovered that lignocellulosic biomass degradation and material functionalization were achieved by DES treatment. Preliminary adsorption tests showed an over fourfold increase in capacity upon modification. The kinetic parameters implied that adsorption on modified material followed the pseudo-second-order kinetic model. Different isotherm models were applied to experimental data, while the Sips isotherm model best describes the equilibrium of the adsorption process on the tested modified material. According to this isotherm model, the maximum achieved adsorption capacities of Cu(II), Zn(II), and Se(IV) were 48.21, 55.06, and 87.85 mg/g, respectively. The summarized experimental results revealed that the adsorption process of selected cations on modified OS was predominantly caused by chemisorption, while, in addition to chemisorption, electrostatic forces were also responsible for Se(IV) removal. Desorption test showed that the prepared material could be reused for at least 3 cycles, with minimal efficiency loss. Briefly, this study reinforces that DES-modified agro-waste biomass could be used as a promising adsorbent for cations and oxyanions from wastewater.

AB  - Worldwide consumption of pesticide active ingredients reaches 2.7 million tons per
year [1]. After being released into the environment significant portion of applied pesticides
ends up in surface water bodies affecting nontarget organisms. Due to high environmental
pollution, improvement in technological practices for water treatment has been a demand,
and advanced oxidation processes stand out as a prominent method. In this study,
photocatalytic degradation of a fungicide difenoconazole was investigated and residual
toxicity was assessed using zebrafish embryos (Danio rerio).
Difenoconazole has been subjected to photocatalytic degradation in presence of the
TiO2 Degussa P-25 catalyst and artificial illumination (Osram Ultra Vitalux 300 W).
Influence of different anions (carbonate, sulphate and nitrate), concentration of pesticide and
mass of catalyst, on degradation process has been assessed. Decrease in absorbance
(Shimadzu 1800 UV spectrophotometer) served as an indicator of the pesticide
concentration in the reaction system. The environmental acceptability of the specified
degradation process was assessed for optimal circumstances of total photodegradation.
Residual toxicity of degradation product was assessed on the basis of toxicity comparison
of initial, partly and completely degraded samples, according to OECD 210 [2].
Embryotoxicity assays were performed in triplicate and were terminated 120 hours post
fertilization (hpf).
According to the results of assays engaged in assessment of the influence of the ions
on photocatalytic processes, it was found that all ions have comparable catalytic effects on
the kinetics of the difenoconazole degradation process. The presence of sulphates and
carbonates had the greatest catalytic effect, while the nitrate ions showed the lowest catalytic
capacity (Fig. 1). The most suitable conditions for photodegradation were obtained by using
0.2 g/l of TiO2 and 5 mg/l of difenoconazole solution at atmospheric conditions. The
embryotoxicity assays followed the analytical examination. Comparison of results obtained
in embryotoxicity assays of the initial solution, partly and completely degraded samples
confirmed suitability of applied degradation method. Significant decrease in toxicity,
compared to the initial solution, was registered in both degraded samples. Based on
cumulative mortality (120 hpf), medium lethal concentration (LC50) of difenoconazole is 1.4
mg/l, while the same parameter could not be determined in partly and completely degraded
samples, due to the lack of mortality (Fig. 2).
According to the obtained results it can be concluded that engaged photocatalytic
degradation process is suitable for pesticide contamination water management.

AB  - Due to the rapid development of industry and growth of population, water consumption is increased.
Beside this, releasing of xenobiotics, which represent significant pollutants into watercourse, like
heavy metal ions, pesticides, paints, and solvents, made this problem much bigger. Therefore, they
can enter into aquatic organisms directly from industrial plants or into human bodies indirectly
through agricultural products. New technologies, including photocatalytic decomposition, are
necessary for wastewater treatment as a highly efficient and low-cost process. Photocatalysis implies
the degradation of various types of harmful organic substances to simple molecules such as CO2, SO2,
ions, and water. The applied process has no detrimental effect on the environment and does not require
additional chemicals for precipitation of the products. In this work, photodegradation of the pesticide
difenoconazole (DFC) using a TiO2-based photocatalyst was examined using doubled wall
thermoregulated quartz reactor. As a replacement for UVC radiation, solar imitated Ultra Vitalux
(UV) lamp (300W) was used. Determination of DFC concentration was performed using a UV
method. Degradation kinetics follows pseudo-first order. After 120 minutes, the DFC was completely
degraded. Chemical oxygen demand (COD) also confirmed that successfully indicating that this
process can be used in treating of industrial wastewater.

AB  - Elderberry (Sambucus nigra) pith was modified with polyethyleneimine (PEI) in order to improve the adsorption properties. Characterization of both dried Sambucus nigra pith (DSNP) and amino modification of elderberry pith with branched PEI (PEI/DSNP) was performed by: Fourier-transform infrared spectroscopy (FTIR), optical microscopy, and porosity determination. The amine and ester number, as well as acid value, were determined on DSNP and PEI/DSNP samples using standard volumetric methods. The samples were used as adsorbents for Pb2+ ions from an aqueous solution in a batch system. The obtained results were fitted using suitable equilibrium isotherm and kinetic models. The maximum adsorption capacity for Pb2+ ions on DSNP and aminated sample, obtained using Langmuir adsorption isotherm at 298 K, are 18.9 and 47.8 mg g(-1), respectively. Based on the kinetic studies, the adsorption process follows the pseudo second-order model. Thermodynamic parameters showed that the adsorption process is endothermic and spontaneous. In general, the overall adsorption process was improved by modifying starting material with branched PEI modifier by introducing large numbers of amino functionalities having high affinity to cations.

AB  - During a fire, passive fire protection systems are designed to prevent the spread of flames, smoke, and toxic gases. The new fire-retardant (FR) material, used for passive fire protection, is created by combining copolymers (VC-co-VAc) (Slovinyl KV 173) and PVC K70 with expanded graphite and plasticizers/modifiers such as diisononyl phthalate - DINP, diisononyl terephthalate - DINTP, dioctyl adipate - DOA, as well as plasticizers that are synthesized based on tertiary recycling of waste poly(ethylene terephthalate) (PET), 1-hexadecene, azodicarbonamide (ADC), tri(p-cresyl phosphate), epoxidized soybean oil (ESO) and acrylate emulsion (DH50, Ecrylic, or Flexryl, etc.). The obtained material's morphology was examined using an emission scanning electron microscope (FESEM) field. Tensile testing was used to determine the mechanical properties of the obtained samples, as well as Shore A hardness and toughness using the Charpy impact test. All samples obtained were tested according to non-flammability standards. To conform to the new trend of "green economy," the development of novel eco-friendly FRs with improved thermal and mechanical properties will include careful consideration of environmental protection and sustainable development.

AB  - Pesticides are substances designed to protect plants
from various types of diseases and pests [1]under UV irradiation
is studied using synthesized Zinc oxide (ZnO.
Synthetic organic pesticides, in addition to the high
efficiency, have led to frequent adverse environmental
impact, as a consequence of their high accumulation
and toxicity. Due to the increased pollution of water
with mixture pesticides, it is necessary to use different
processes for their removal and degradation. Therefore,
oxidative processes have been developed, commonly
named as Advanced Oxidation Processes (AOPs).
Among them, special attention was attributed to photocatalysis,
as a process that enables the degradation
of difficult-to-decompose organic molecules under the
action of UV radiation in the presence of catalysts [2].
In this study the photocatalytic degradation of thiophanate-
methyl (TM) in the presence of the TiO2 Degussa
P-25 catalyst was investigated. Different experimental
conditions were varied, such as the concentration of
the pesticide solution, the mass of the catalyst and the
influence of the anions (chloride, sulphate, nitrate, etc.).
The pesticide concentration in the reaction system was
monitored based on the decrease in system absorbance
using a Shimadzu 1800 UV spectrophotometer. For optimized
conditions of complete photodegradation, the
environmental acceptability of the defined degradation
process was examined. The toxic effect of the TM solution
before and after degradation was examined using
the embryotoxicity test with Danio rerio, in order to
prove the reduction of toxicity and the success of the
degradation process [3]which raises the issue of potential
influence of different formulation types on herbicide
toxicity. The present study evaluated the toxicity and
teratogenic effects of the active ingredient clomazone
and its two formulations (Rampa® EC and GAT Cenit
36 CS, both containing 360 g a.i./l of clomazone.
Comparing the obtained results of the influence of
ions on the processes of photocatalysis, it was noticed
that all ions have catalytic effects on the kinetics of the
degradation process of TM. The presence of sulphates
and carbonates had the greatest catalytic effect, while
hydrogen phosphates and bicarbonates showed the lowest
catalytic capacity.
The optimal experimental conditions were obtained
using 0,2 g/L of TiO2 and 5 mg/L of TM solution. In
addition, the embryotoxicity test followed the analytical
examination. Comparison of results obtained in embryotoxicity
assay testing of the initial solution, partly
and completely degraded samples confirmed suitability
of applied degradation method. Increase in toxicity,
compared to the initial solution, was registered in partly
degraded sample. This observation can be attributed to
increase in concentration of carbendazim (TM metabolite)
more toxic than parent substance. Finally, completely
degraded sample caused no mortality or adverse
effects in D. rerio embryos after 120 h exposure. Toxicity
of samples, in decreasing order is half degraded >
initial >completely degraded sample.
Based on the obtained results it can be concluded
that used photocatalytic degradation process can be successfully
applied in pesticide contaminated water management.

AB  - With the development of the industry and growth of
the population, there is an increasing amount of waste,
which, due to inadequate treatment, pollutes water. The
group of the most dangerous pollutants present in water
includes heavy metals, such as As, Cd, Pb, Ni, Hg, Cr,
etc. [1]. Heavy metal ions are highly toxic and not biodegradable,
but are prone to accumulation in the body in
certain tissues and organs [2].
In recent years, natural materials, originating from
waste or renewable sources, have been increasingly
used as adsorbents in the removal of heavy metal ions
from water, due to their low cost, high prevalence and
beneficial impact on the environment [3]. Lignin, cellulose
and hemicellulose are the main polymers of wood
biomass [4]. Lignin is represented as a by-product in the
paper and pulp industry [5]. Chemical modification of
lignin was performed using acrylate derivatives (L-AC).
Modified lignin microspheres (LMS) were synthesized
by inverse suspension copolymerization using L-AC,
trimethylolpropane triacrylate (TMPTA) and methacryl
functionalized magnetite modified with MEMO silane
or with methacryloyl chloride (MACM1 or MACM2).
The procedure of inverse emulsion-suspension copolymerization
developed by Popović et al. [6] was used. In
a summary, disodium laureth sulfosuccinate (surfactant)
was stirred in water solution for 30 min at 80 °C. Afterwards,
TMPTA, L-MAC, MACM1 or MACM2 and the
initiator AIBN (1 wt. %) were added, followed by the
mixture of pore-forming solvents (tetradecanol and toluene),
stirred for 18 h at the same elevated temperature.
LMS microspheres were characterized by zero
charge point determination, FT-IR and SEM. The efficiency
of pollutants (chromium(VI) and arsenic(V)
ions) removal was analysed in terms of varying the
experimental conditions: the mass of adsorbent, the pH
of solution, the temperature of reaction and the contact
time. The best sorption was observed for the pH between
5.0 and 7.0. Synthesized bio-adsorbents showed
high efficiency, with capacities of 35.5 and 54.0 mg g-1
for the LMS adsorbents loaded with magnetite modified
using methacyl functionalized silane (LMS-1) or
methacryloyl chloride (LMS-2), respectively, obtained
according to Freundlich isothermal model. Adsorption
kinetics are described according to a pseudo-second
order model. Based on the obtained results, both adsorbents
showed excellent adsorption abilities.
Thermodynamic parameters, including the Gibbs
free energy (ΔGΘ), enthalpy (ΔHΘ) and entropy (ΔSΘ),
proved that adsorption is viable, spontaneous and endothermic
process (LMS-1) and exothermic process
(LMS-2) at temperatures between 25 and 45 °C.

AB  - A simple sol-gel method and external gelatinization method of hollow alumina spheres synthesis were developed in this study. The spheres were modified with polyethyleneimine (PEI) producing PEI-Al2O3 via (3-glycidyloxypropyl)trimethoxy-silane, GLYMO, linker. Characterization results, obtained using XRD and SEM microscopy revealed spherical geometry with a hollow core of PEI-Al2O3 adsorbent. Introduction of a large number of the amino group, 6.9 mmol g(-1), contributes to achieving high adsorption capacities, q(m), of 95.6, 124.9, 61.3, and 125.9 mg g(-1) for Cd2+, Pb2+, As(V), and DCF, respectively, which is obtained by using the Langmuir model. Thermodynamic studies indicated feasible adsorption and higher spontaneity with temperature increase. The kinetic study conveniently modeled using pseudo-second-order (PSO) and Weber-Morris kinetic model, as well as single resistance mass transfer model, indicated a change of the contribution of diffusional processes during adsorption with a dominance of intra-particle diffusion. The fixed-bed column adsorption data, fitted using Bohart-Adams, Clark, Yoon-Nelson, and Thomas models, showed lower capacity in comparison to batch study, and thus clear potential applicability of PEI-Al2O3 was deduced even at a high loading of feed water.

AB  - In-depth kinetic and column adsorption study for diclofenac, DCF, heavy-metal and oxyanions adsorption on highly effective amino-functionalized lignin-based microsphere adsorbent (A-LMS) is examined. The A-LMS was synthesized via inverse suspension copolymerization of industrial kraft lignin with the amino containing grafting-agent (polyethylene imine), and an epoxy chloropropane cross-linker. The batch adsorption results indicated process spontaneity and feasibility of a high removal capacity: DCF(151.13) >>Cd2+(74.84)>Cr(VI)(54.20)>As(V)(53.12)>Ni2+(49.42 mg g(-1)). The quantum chemical calculated interaction energies reveal stabilization of the A-LMS/DCF complex through the electrostatics and van der Waals interactions. The results from the pseudo-second order and Weber-Morris fitting indicate a fast removal rate; thus, column tests were undertaken.

abstract = "In-depth kinetic and column adsorption study for diclofenac, DCF, heavy-metal and oxyanions adsorption on highly effective amino-functionalized lignin-based microsphere adsorbent (A-LMS) is examined. The A-LMS was synthesized via inverse suspension copolymerization of industrial kraft lignin with the amino containing grafting-agent (polyethylene imine), and an epoxy chloropropane cross-linker. The batch adsorption results indicated process spontaneity and feasibility of a high removal capacity: DCF(151.13) >>Cd2+(74.84)>Cr(VI)(54.20)>As(V)(53.12)>Ni2+(49.42 mg g(-1)). The quantum chemical calculated interaction energies reveal stabilization of the A-LMS/DCF complex through the electrostatics and van der Waals interactions. The results from the pseudo-second order and Weber-Morris fitting indicate a fast removal rate; thus, column tests were undertaken. The single resistance mass transfer model, i.e. the mass transfer (kfa) and diffusion coefficient (Deff), shows pore diffusional transport as a rate limiting step.

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  - The study of the synthesis of anticorrosive inhibitors, based on chemically modified tannins, and their use in alkyd based coatings to improve anticorrosive properties is presented in this work. Two methods of tannin modification were applied: direct method using ammonium hydroxide, ammonium hydroxide/ammonium chloride buffer or diethylenetriamine (DETA); and a two-step method including tannin modification with epichlorohydrin (ECH) in first step to produce epoxy modified tannin, ET, and further modification with heteroaromatic amines or linseed oil fatty acids (LFA) in second step. The obtained anticorrosive additives were characterized using ATR-FTIR, 1H and 13C NMR spectroscopies and elemental analysis. Epoxy, amino, hydroxyl, acid and iodine values of the synthesized inhibitors were determined according to standard methods. The prepared alkyd coating with tannin inhibitors was tested according to standard SRPS EN ISO 4628 method. Anticorrosive coating containing modified tannin based additive showed increased anticorrosive properties, good adhesion and coverage comparing to the coating with zinc phosphate additive. The alkyd coating films based on ET-LFA and ET modified with 2-amino-5-mercapto-1,3,4-thiadiazole showed best anticorrosive results.

AB  - This paper aims to determine the 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 chemical methods (AAS, AES, gravimetric analysis, XRF), physicochemical methods (XRD, FTIR, SEM, DTA, DTG) and physical methods (porosity measurement, Microscopy in transmitted light). Also, equilibrium adsorption capacity was determined. All the results of adsorption capacity were satisfying considering the mineral composition, granulation, and porosity. The removal efficiency of chromates was the biggest (above 30 %) with adsorption capacity of 15.6 mg Cr g(-1). The lowest adsorption efficiency was with the selenates, approximately 18 %.
