AB  - The corrosion of the transport tank materials made of stainless steel 316Ti is investigated in a solution containing 12–15% of the commercial sodium hypochlorite solution. Using the electrochemical techniques, weight loss measurements, and optical microscope, it is shown that corrosion occurs due to the metastable pitting. It is proposed that formed metal oxides corrosion product could catalyzed chemical decomposition of hypochlorite solution to oxygen, which provokes the positive shift of the corrosion potentials into the region of metastable pitting.

AB  - Globalno zagrevanje i porast prosečne temperature doveli su do pojave cijanobakterija posebno u stajaćim vodama. Posebnu opasnost za zdravlje su toksini koje ove bakterije proizvode usled neadakvatnog tretmana. Razni toksini mogu izazvati osip na koži, mogu dovesti do raka jetre, a neki od njih su jaki neurotoksini. Iz ovih razloga neophodno je da se cijanobakterije uklone pre nego dodju u pogon finalne prerade vode. Rezultati laboratorijskih ispitivanja na cijanobakterije posle tretmana cevovoda sprovedeni u Zavodu za javno zdravlje Srbije i laboratorija JKP Beogradski vodovod pokazali su posle izvršenih procesa čišćenja, pranja i dezinfekcije znacajno smanjenje broja cijanobakterija. Pokazano je da je KMnO4 efikasno sredstvo za suzbijanje cijanobakterija u koncentraciji do 25 mg/l.
AB  - It was noticed worldwide that nutrient enrichment and climatic change as global warming and hydrologic changes with periods of more intense droughts strongly affect cyanobacterial growth. Toxigenic cyanobacteria that can produce a wide range of cyanotoxins (hepato-, neuro-, dermatotoxins) are one of the major health risks humans and animals are exposed to via drinking water. Therefore, it is important to remove the cyanobacteria before the water comes to a plant for a final treatment. Results of laboratory examination carried out by National Public Health Institution of Serbia and Belgrade Waterworks and Sewerage shows significant reduction of number of cyanobacteria aftre our treatment with KMnO4. The efficiency of the treament is the highest when concentration of KMnO4 was 25 mg/l.

AB  - U radu je prikazan postupak za čišćenje i dezinfekciju vode u bunarima velikih kapaciteta Beogradskog vodovoda. Tipičan primer bunara velikih kapaciteta je Reni bunar 2 i 4 koji su locirani na 50m od leve obale Save u neposrednoj blizini ušća Save u Dunav. Bunari su dubine oko 30m, prečnika 4 m i sadrže oko 300 m3 vode i sa horizontalnim drenovima dužine 50m. Prezentovan je jednostavan i jeftin način za hiperdezinfekciju bunarskog dna i bunarske vertikale. Takođe je pokušano da se tretiraju i unutrašnjost drenova koji napajaju ovakve bunare.
AB  - We show in this work the treatment procedure utilized for cleaning and desnfection of water in water wells of large capacity as in the case of wells of Belgrade Waterworks. The typical examples of such well of large capacity are Reni wells 2 i 4 located 50m from the left bank of the river Sava and in close geometrical distance of confluence of Save river into the Danube. The depth of wells is around 30 m, diamaeter of around 4 m with approximat content of 300 m3 of water. In this work, we demonstate a simple but innovative approach for the disinfection of the well bottom, vertical areas along the well and inner inlets that pump in the water into the well.

AB  - Magnetic particles (MAG), obtained by standard procedure of coprecipitation of Fe2+ and Fe3+ in an excess of ammonia, and polyaniline modified magnetic particles MAG-PANI were used as carriers for immobilization of α-amylase from Bacillus licheniformis. The formation of a polyaniline layer (PANI) on MAG particles was achieved by chemical polymerization of aniline. Immobilization was carried out by adsorption, as a simple, inexpensive and fast method that allows retention of a large portion of the initial activity of the immobilized enzyme. FTIR spectroscopy was used to characterize the obtained particles and to confirm changes dueto formation of a PANI layer and conjugation of α-amylase on the particle surfaces. Particle size distribution was bimodal and three-modal for MAG and MAG-PANI, respectively. Appearance of a fraction of smaller MAG-PANI particles than MAG particles could be attributed to the formation of PANI particles without the MAG core. Measured values of Zeta potential for MAG-PANI were higher as compared to MAG indicating stabilization of particles in the presence of PANI. Relevant kinetic parameters for immobilized enzyme were determined from the Hanes plot. The apparent Km constant was 1.91 and 1.48 g L–1 for MAG-A and MAG-PANI-A, respectively, while Vm was 0.19 g L–1 min–1 for MAG and 0.32 g L–1 min–1 for MAG-PANI. The obtained values of Km indicated that modification of MAG by PANI enhanced kinetic properties of the immobilized enzyme. Moreover, the modification of MAG by PANI showed the increase in both pH and thermal stabilities of the immobilized enzyme. Studies of the operational activity of the immobilized enzyme on MAG-PANI have shown that 98.8% of starch was hydro-lyzed over 20.0 min. In the first cycle in the packed bed reactor operated in a recycling mode, but approximately five times longer period was required to hyd-rolyze 93.5 of starch in the fifth cycle. In the continuous packed bed reactor without recycling, the degree of starch hydrolysis was not changed significantly during 4 h and was 88.8±1.6%, whereas the half-life of the biocatalyst was 6.2 h. Although coating MAG particles with a polyaniline offers many advantages, the main disadvantage is possible appearance of residues of aniline monomers and dimmers. The potential toxicity of these residues requires precise composition analysis of the product of starch hydrolysis catalyzed by α-amylase adsorbed onto MAG-PANI. © 2018, Association of Chemists and Chemical Engineers of Serbia.

AB  - The electrochemical oxidation of the urea in near neutral pH is investigated on platinum electrode. It is shown that oxidation reaction is practically inhibited up to the potentials of ∼0.9 V. The same reaction is investigated onto electrochemically obtained titanium dioxide nanotubes modified by hematite using facile, low-cost successive ion layer adsorption and reaction (SILAR) method. It is shown that such system possesses electrocatalytic activity at very low potentials, and activity can be further improved by the illumination of the electrode in the photo-assisted reaction. The possible application of the photoactive anode is considered in the application of urea based water electrolysis and urea based fuel cell.

AB  - An environmentally friendly cell using polypyrrole-air regenerative cathode and zinc as anode is investigated in the 3% sodium chloride solution. The cell can operate in different charge and discharge mode. Polypyrrole can be reoxidized (doped) with chloride anions either by using dissolved oxygen or by an external power supply, e.g., small photovoltaic cell. In that way, after discharge, capacity retaining can be achieved by using seawater as the electrolyte. During low discharge rate, the delicate balance between solid state diffusion-controlled dedoping and chemical oxidation of polypyrrole produced by hydrogen peroxide is achieved, generating stable voltage plateau. The cell is proposed to operate as a power supply for different sensor devices in two modes. In the low discharge mode (10–20 mA g−1), it can be used for data acquisition, and at the fast discharge mode (up to 2 A g−1) for collecting data transmission.

AB  - Poly(aniline-co-(m-aminobenzoic acid)) was synthesized electrochemically at graphite electrode under galvanostatic conditions. Aqueous electrolyte for synthesis was consisted of HCl and different amount of aniline and m-aminobenzoic acid. The presence of the meta positioned carboxylic group in m-aminobenzoic acid influenced higher co-polymerization potential, different morphology and electrochemical behavior of copolymers compared to polyaniline. Electrochemical activity is achieved by proton exchange in neutral environment that can result in a faster charge/discharge process, which is in the case of PANI limited by slow anion exchange, making this material promising for consideration in super-capacitors and in biological system.

AB  - Novel TiO2-PANI core-shell nanocomposite, prepared by in situ oxidative polymerization of aniline in the presence of TiO2 nanoparticles surface modified with vitamin B6, was used to reinforce epoxy resin. The size of prepared TiO2 nanoparticles and TiO2-PANI nanocomposite were determined by a transmission electron microscopy (TEM). The surface modification of TiO2 nanoparticles was confirmed by FTIR and UV–vis spectroscopy, while the morphology of PANI and TiO2-PANI nanocomposite was investigated by scanning electron microscopy (SEM). The influence of TiO2-PANI nanocomposite on glass transition temperature, dielectric and dynamic mechanical properties, thermooxidative stability, mechanical and anticorrosion properties of epoxy based nanocomposites was investigated and compared to the properties of epoxy/PANI nanocomposites. It has been observed that the glass transition temperature of epoxy resin increases after introduction of PANI and TiO2-PANI nanocomposite, as well as with increasing their content. Prepared nanocomposites exhibited higher value of dielectric constant than pure epoxy resin. Epoxy based coating containing TiO2-PANI nanocomposite showed lower dielectric loss, higher hardness and better anticorrosion properties than pure epoxy resin and epoxy/PANI nanocomposite.

The open circuit voltage of 0.52 V and short circuit current of ∼3.6 µA/cm2 are obtained, with the maximum specific power of ∼1 µW/cm2. The influence of internal resistance of the cell is discussed. Decolorization is investigated under open circuit potentials, and under external load of 3.3 kΩ conditions. In both cases, 40% of decolorization is achieved, but are three times faster under external load conditions. Specific energy during decolorization in such cell is estimated to ∼5 mWh/m2.

AB  - The immobilization of α-amylase via adsorption on magnetic particles coated with polyaniline was studied. The support was characterized by field emission scanning electron microscopy (FESEM). The obtained magnetic particles were agglomerates of nanoparticles with sizes below 100 nm. The effects of various factors on immobilization, including time, the initial enzyme concentration, pH, and temperature, were examined. The optimum pH, temperature, and time for immobilization were established to be 7, 45°C and 75 min, respectively. The maximum amount of adsorbed α-amylase of 10/100 mg support was determined at the 5 mg/mL enzyme concentration. It appeared that α-amylase was stabilized in terms of pH and temperature by adsorption on magnetic particles coated with polyaniline. The good agreement of the equilibrium data with the Langmuir isotherm model confirmed the monolayer coverage of enzyme molecules on the surface of magnetic particles, and the maximum adsorption capacity was found to be 55.6/100 mg support at 25°C. The biocatalyst retained 55.5 ± 1.63% of its initial activity after nine cycles of reuse in starch hydrolysis at 60°C in a batch reactor. The immobilized enzyme also showed very good storage stability.

AB  - Due to unique properties of intrinsically conducting polymers (ICP) such as: electrical conductivity, reversible electrochemistry, optical activity, biocompatibility, environmental and corrosion stability, they still represent a base for both theoretical and practical studies. The mentioned properties open up possibilities for practical application in the field of electrochemical systems for energy storage and conversion, sensors, biosensors, antistatic coatings, magnetic shielding, active corrosion protection etc. Bearing in mind that nanostructurization of materials lead to improvement of physical and chemical properties, there is a growing interest in the development of nanosized ICP. Nanosized ICP can be prepared by both chemical and electrochemical procedures. Although chemical synthesis is a common approach, there are also not a few studies of electrochemical synthesis of ICP. The aim of this paper is to review literature dedicated to electrochemical formation of nanostructured ICP with special attention dedicated to polyaniline and polypyrrole as the most popular ICPs.
AB  - Interesovanje za elektroprovodne polimere kako u teorijskom tako i praktičnom smislu utemeljeno je u jedinstvenim svojstvima ovih materijala, kao što su: kontrolisana električna provodljivost, reverzibilna oksidacija redukcija (dopovanje/dedopovanje), optička aktivnost, bio-kompatibilnost, korziona postojanost itd. Ova svojstva otvaraju mogućnosti praktične primene u oblasti elektrohemisjkih primarnih i sekundarnih izvora električne energije, elektrohemijskih kondenzatora, senzorima, biosenzorima, aktivnoj zaštiti od korozije. Imajući u vidu da nanostrukturizacija materijala dovodi do značajnog poboljšanja fizičkih i hemijskih svojstava materijala postoji veliko interesovanje za proučavanje nanostruktuirasnih elektroporvodnih polimera. Nanostruktuirani elektroprovodni polimeri mogu se dobiti hemijskim i elektrohemijskim postupcima sinteze. Iako je hemijska sinteza zastupljenija, u literaturi može se naći značajan broj radova posvećen elektrohemisjkom formiranju nanostruktuiranih elektroprovodnih polimera, pa je upravo i ovaj tekst posvećen toj probelmatici, u prvom redu elektrohemisjkom formiranju nanostruktura polianilina i polipirola kao najznačajnijih predstavnika elektroprovodnih polimera.

AB  - The potential characteristics of graphite felt electrodes, modified by iron oxide, for oxygen reduction are evaluated. Modification is carried out by Successive Ion Layer Adsorption and Reaction (SILAR) method, using a solution of ferric nitrate in methanol for the adsorption of ions, and a solution of sodium hypochlorite for reaction. The reaction activity of the oxygen reduction from the air, in sodium sulfate based solution varying the number of SILAR cycles, as well as the influence of pH is investigated. By comparing the activity with pure platinum, similar activity is obtained at pH = 9.2, as well as good electrode stability. Possible mechanism of the oxygen reduction on the graphite felt modified by iron oxide is discussed.

Successive ion adsorption and reaction (SILAR) is applied to decorate an electrochemically formed TiO2 nanotube electrode. The anodic photoelectrochemical behavior of pure TiO2-NT’s and modified electrodes are investigated in a sulfate containing solution at pH = 9.2. It is shown that such a modification leads to an increase of anodic photoactivity, as well as that at the same current density, the photoelectrochemical cell with a modified electrode operates at a voltage lower by 0.7 V. The band gap and flat band potentials are estimated, and the structure of the band gap and possible charge transfer reactions and mechanism are discussed.

AB  - Polypyrrole enzyme electrode was formed by immobilization of glucose oxidase via glutaraldehyde into electrochemically synthesized polypyrrole on glassy carbon electrode. Electrochemical synthesis was performed in 0.5 mol dm(-3) HCl and 0.2 mol dm(-3) pyrrole at constant current density of 2 mA cm(-2). Chronopotentiometric curves of polypyrrole enzyme electrode were recorded at current density of 42 nA cm(-2) for different glucose concentrations. The determined value of the apparent Michaelis-Menten constant was 0.045 mmol dm(-3) which is significantly lower than that of free enzyme indicating enhanced enzyme efficiency when it is immobilized into electroconducting polymer matrix.

AB  - The electrochemically synthesized polypyrrole and lead-lead sulfate is examined as a potential electrodes for battery-type hybrid supercapacitors in acidic solution. The device exhibits battery-type behavior at low discharge rate, e.g. <0.5 A g−1, and supercapacitors-type behavior at a higher discharge rate. Discharge in the specific current range of ∼0.6–2.27 A g−1 based on the active masses, can deliver capacity of 90–72 Ah kg−1, energy of 58–40 Wh kg−1 and power of 40–1350 W kg−1, with the specific capacitance of the cell in the range of 300–250 F g−1. The experimentally obtained values are compared with theoretical.

AB  - Electrochemical formation of polyaniline (PANI) modified electrode was performed galvanostatically from aqueous solution of 1.0 mol dm-3 HCl containing 0.2 mol dm-3 aniline at current densities ranging from 0.5-3.0 mA cm-2. The morphology of PANI electrode consisted of highly developed nanofibrous network with electrocatalytic features towards oxidation of ascorbic acid, reflected in increase of the peak current ~ 2.5 times and shift of the oxidation potential by 0.32 V to less positive values. Response of PANI modified electrode was obtained from anodic LSV curves. Current peak potentials decreased with increase of pH with slope of ~ 32 mV pH-1, indicating two electron charge transfer process with liberation of one proton characteristic of an electrochemical reaction followed by a chemical step. © 2015 The Authors.

AB  - The protective abilities of composite coatings based on electrochemically and chemically formed polyaniline powder against the corrosion of mild steel were investigated. A polyaniline powder has been prepared in the form of an emeraldine base and benzoate salt through chemical dedoping and doping. The composite coatings using polyaniline powders, which were obtained through different routes, and base coatings, which were not corrosion-resistant, with different formulations were prepared and applied on mild steelsamples. The corrosion was investigated using an electrochemical impedance technique in 3% NaCl, andthe atmospheric corrosion was assessed in a humidity chamber. Emeraldine-benzoate salts, which area chemically synthesized polyaniline, offer the best protection with an optimal polyaniline concentration of approximately 5 wt%. The different corrosion behaviors were assessed relative to the presence of aniline oligomers in the samples after characterization using UV-vis spectrophotometry. Upon comparison between the corrosion behavior in 3% NaCl with commercial primer paint for iron and that with apaint containing 5 wt% PANI, the composite coating has superior anticorrosion characteristics. The mech-anism for the protection of mild steel from corrosion through composite polyaniline coatings was also considered. © 2014 Elsevier B.V. All rights reserved.
