AB  - Ceria coating is formed on Al from the ceria sol prepared exclusively by forced hydrolysis of Ce(NO3)(4), in order to test their ability to protect Al from corrosion. The characterization of sol-gel-processed ceria coating and coating/Al assembly brings new issues on Al corrosion and protection caused by unique properties of the sol-gel coating. The corrosion behaviour of bare Al and Al/CeO2 is investigated by the electrochemical impedance spectroscopy (EIS) during the exposure to NaCl aqueous solution. The morphology and composition of the samples are examined by scanning electron microscopy and energy dispersive spectroscopy. EIS data showed greater corrosion resistance of CeO2-coated aluminium in comparison to bare Al at long exposure times. CeO2 coating does not hinder completely the corrosion processes on Al. The Al beneath CeO2 coating is subjected to intrinsic formation of a uniform protective coating/Al interphase, cross-linked by AlO(OH) fibre-like structures. They appear created by corrosive medium from the coating reversely gelled by NaCl solution. As the fibre network is created during exposure, Al becomes better protected than by spontaneous formation of porous passive layer of Al(OH)(3) on bare aluminium. Sol-gel ceria coatings thus improve corrosion resistance of aluminium during prolonged exposure to corrosive medium.

AB  - CeO2 coatings were formed on the aluminum after Al surface preparation, by dripping the ceria sol, pre­viously prepared by forced hydrolysis of Ce(NO3)4. The anticorrosive properties of ceria coatings were investigated by the electrochemical impedance spectroscopy (EIS) during the exposure to 0.03% NaCl. The morphology of the coa­tings was examined by the scanning electron microscopy (SEM). EIS data indicated considerably larger corrosion resistance of CeO2-coated aluminum than for bare Al. The corrosion processes on Al below CeO2 coating are sub­jected to more pronounced diffusion limitations in com­parison to the processes below passive aluminum oxide film, as the consequence of the formation of highly com­pact protective coating.

AB  - The electrochemical characteristics of Ti0.6Ir0.4O2/Ti and Ti0.6Ru0.4O2/Ti anodes prepared by the sol-gel procedure from the corresponding oxide sols, obtained by force hydrolysis of the corresponding metal chlorides, were compared. The voltammetric properties in H2SO4 solution indicate that Ti0.6Ir0.4O2/Ti has more pronounced pseudocapacitive characteristics, caused by proton-assisted, solid state surface redox transitions of the oxide. At potentials negative to 0.0 VSCE, this electrode is of poor conductivity and activity, while the voltammetric behavior of the Ti0.6Ru0.4O2/Ti electrode is governed by proton injection/ejection into the oxide structure. The Ti0.6Ir0.4O2/Ti electrode had a higher electrocatalytical activity for oxygen evolution, while the investigated anodes were of similar activity for chlorine evolution. The potential dependence of the impedance characteristics showed that the Ti0.6Ru0.4O2/ /Ti electrode behaved like a capacitor over a wider potential range than the Ti0.6Ir0.4O2/Ti electrode, with fully-developed pseudocapacitive properties at potentials positive to 0.60 VSCE. However, the impedance characteristics of the Ti0.6Ir0.4O2/Ti electrode changed with increasing potential from resistor-like to capacitor-like behavior.

Voltametrijske karakteristike u rastvoru H2SO4 ukazuju na više izraženo pseudokapacitivno ponašanje Ti0,6Ir0,4O2/Ti elektrode koje je posledica površinskih redoks prelaza u čvrstom stanju uz učešće protona. Na potencijalima negativnijim od 0,0 VZKE ova elektroda pokazuje slabu provodnost i aktivnost, dok voltametrijskim ponašanjem Ti0,6Ru0,4O2/Ti elektrode dominira prodor protona u strukturu oksida.

AB  - Titanium oxide is applied as a photocatalyst in organic synthesis and for waste water treatment and outdoor air purification. In this work, photoelectrochemical (PEC) activity of titanium oxide coating on titanium substrate, prepared by the sol–gel procedure from the oxide sol obtained by forced hydrolysis of chloride was investigated. Electrochemical and PEC parameters at photoelectrode change intensively upon UV illumination when organic compounds (alcohols, aldehydes, acids, etc.) are present in the electrolyte (H2SO4), which proves coating activity for their oxidation. Electrochemical impedance (EIS) characteristics of the coating are found to be sensitive to the photoelectrode potential and UV light. EIS characteristics are discussed on the basis of the values of parameters of equivalent electrical circuit used to fit experimental impedance data.

AB  - Electrochemical properties of sol-gel processed Ti(0.6)Ir(0.4)O(2) and Ti(0.6)Ru(0.3)Ir(0.1)O(2) coatings on titanium substrate were investigated using cyclic voltammetry, polarization measurements and electrochemical impedance spectroscopy and compared to the properties of Ti(0.6)Ru(0.4)O(2) coating. The role of iridium oxide in the improvement of the electrocatalytic, capacitive and stability properties of titanium anodes activated by a RuO(2)-TiO(2) coating is discussed. The oxide sols were prepared by forced hydrolysis of the metal chlorides. The characterization by dynamic light scattering and X-ray diffraction showed that polydisperse oxide sols were obtained with the particles tending to form agglomerates. The presence of IrO(2) causes a suppression of the X-ray diffraction peaks of TiO(2) and RuO(2) in the sol-gel prepared Ti(0.6)Ir(0.4)O(2) and Ti(0.6)Ru(0.3)Ir(0.1)O(2) coatings. The IrO(2)-containing coatings had an enhanced charge storage ability and activity for the oxygen evolution reaction (OER) in comparison to Ti(0.6)Ru(0.4)O(2) coating. The voltammogram of the Ti(0.6)Ir(0.4)O(2)/Ti electrode showed well-resolved peaks related to Ir redox transitions, which are responsible for the enhanced charge storage ability of IrO(2)-containing coatings. Redox transitions of Ir were also registered in the high-frequency domain of the ac impedance spectra of the coatings as a semicircle with characteristics insensitive to the electrolyte composition and to the electrode potential prior to OER. However, the semicircle characteristics were different for the two IrO(2)-containing coatings, as well as at potentials outside the OER in comparison to those at which the OER occurs.

The voltammogram of the Ti(0.6)Ir(0.4)O(2)/Ti electrode showed well-resolved peaks related to Ir redox transitions, which are responsible for the enhanced charge storage ability of IrO(2)-containing coatings. Redox transitions of Ir were also registered in the high-frequency domain of the ac impedance spectra of the coatings as a semicircle with characteristics insensitive to the electrolyte composition and to the electrode potential prior to OER. However, the semicircle characteristics were different for the two IrO(2)-containing coatings, as well as at potentials outside the OER in comparison to those at which the OER occurs.",

AB  - In this work, electrophoretic deposition (EPD) was applied to obtain novel hydroxyapatite (HAP)/lignin (Lig) biocomposite coatings on titanium substrate. Nanosized hydroxyapatite powder, prepared by using the modified chemical precipitation method, was used for the fabrication of HAP/Lig composite coatings. EPD was performed at different values of constant voltage and constant deposition time. It was confirmed that control over deposited mass can be achieved by applied voltage and time. The uniform and compact coatings were successfully deposited at applied voltage of 60 V in various deposition times lower than 1 minute. The effect of lignin as natural non-toxic polymer on microstructure, morphology and thermal behavior of biocomposite HAP/Lig coatings was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The electrophoretically deposited HAP/Lig coating has been successfully sintered at lower sintering temperature of 900 degrees C, producing non-fractured coating and indicating that lignin may exhibit adhesive role, strengthening the bonding between HAP particles and substrate surface.

AB  - Electrochemical synthesis of nanosized monetite powder was performed galvanostatically from homogeneous Solution of Na(2)H(2)EDTA center dot 2H(2)O, NaH2PO4 and CaCl2 at a concentration relationship Ca/EDTA/PO43- of 0.25/0.25/0.15 M at current density of 137 mA cm(-2) and pH value of 5.0. The synthesized monetite powder was characterized by X-ray diffraction, infrared spectroscopy, size distribution measurements, thermogravimetric and differential thermal analysis and scanning electron microscopy. Monetite powder was electrophoretically deposited on titanium from ethanol Suspension, using constant voltage method. The deposition was performed at constant voltage between 10 and 50 V and for a constant deposition time between 1 and 30 min. The influence of the applied voltage and deposition time on the mass and morphology of monetite deposits was investigated. It was shown that monetite deposits of the highest thickness and the lowest porosity can be formed at lower applied voltage (30 V) and for longer deposition time (20 min) and then converted to hydroxyapatite.

AB  - Itaconic acid, IA (C5H6O4), was investigated as a potential flocculant for the aqueous processing of alumina powders. The adsorption of IA, as a function of its concentration and pH value of the solution, onto the alumina surface was studied by the solution depletion method. The stability of the suspensions in the presence of itaconic acid was evaluated in light of the surface charge of the alumina powder used, the degree of dissociation of IA, as well as the sedimentation behavior and rheology of the suspensions. It was found that the adsorption process is extremely pH dependent; the maximum adsorption of IA onto alumina surface occurring at a pH close to the value of the first IA dissociation constant, pKa1. Also, IA does not influence the value of the point of zero charge of alumina. It was shown that IA represents an efficient flocculant for concentrated acidic alumina suspensions.

AB  - The adsorption mechanisms of Ph2+, Cd2+ and Sr2+ ions on natural sepiolite and the influence of acid treatment on the adsorption capacity of sepiolite were investigated. The point of zero charge pH(pzc), is 7.4 +/- 0.1 for natural sepiolite and 6.9 +/- 0.1 for partially acid-activated sepiolite. The shift of the pH(pzc) of sepiolites toward lower pH values in solutions of Ph2+ and Cd2+ ions indicates that specific adsorption of these cations on natural and acid-activated sepiolites occurred, which was more pronounced for Pb2+ ions than for Cd2+ ions. There was no shift of the pH(pzc) in Solution containing Sr2+ ions, suggesting that specific adsorption of this cation did not occur. The affinity for ion exchange with the Mg2+ ions from the sepiolite structure was the highest for Pb2+ ions, then Cd2+, whereas the affinity for Sr2+ ions was negligible. The adsorption isotherms suggest that the sequence of the efficiency of the sepiolites adsorption is Ph2+ gt Cd2+ gt Sr2+. The retention of Pb2+ and Cd2+ ions by sepiolite occurs dominantly by specific adsorption and exchange of Mg2+ ions from the sepiolite structure. The concentration in the external outer sphere of the Stem layer by electrostatic forces is the dominant mechanism for the retention of Sr2+ ions on the surface of sepiolites. Despite increases in the surface areas upon acid activation, improvements in the adsorption were not observed, as a result of the decreasing number of Mg-OH groups, as main centers for specific adsorption, and the number of Mg2+ ions available for ion exchange with Pb2+, Cd2+ and Sr2+ ions. The removal of Mg-OH groups from the sepiolite also resulted in a decrease in the point of zero charge and an increase of the relative surface acidity, from 2.6 +/- 0.1 for the natural to 6.4 +/- 0.1 for the acid-activated sepiolite.

abstract = "The adsorption mechanisms of Ph2+, Cd2+ and Sr2+ ions on natural sepiolite and the influence of acid treatment on the adsorption capacity of sepiolite were investigated. The point of zero charge pH(pzc), is 7.4 +/- 0.1 for natural sepiolite and 6.9 +/- 0.1 for partially acid-activated sepiolite. The shift of the pH(pzc) of sepiolites toward lower pH values in solutions of Ph2+ and Cd2+ ions indicates that specific adsorption of these cations on natural and acid-activated sepiolites occurred, which was more pronounced for Pb2+ ions than for Cd2+ ions. There was no shift of the pH(pzc) in Solution containing Sr2+ ions, suggesting that specific adsorption of this cation did not occur. The affinity for ion exchange with the Mg2+ ions from the sepiolite structure was the highest for Pb2+ ions, then Cd2+, whereas the affinity for Sr2+ ions was negligible. The adsorption isotherms suggest that the sequence of the efficiency of the sepiolites adsorption is Ph2+ gt Cd2+ gt Sr2+.

AB  - Titanium anodes with an active RuO2 coating of two different thicknesses were prepared from the oxide suspended in ethanol ("ink" method), while the oxide itself was synthesized by the hydrolysis of ruthenium ethoxide in an ethanolic solution (alkoxide route). The morphology of prepared oxide was examined by scanning electron microscopy. The electrochemical properties of the prepared Ti/RuO2 anodes, involving their cyclic voltammetric behavior in H2SO4 and NaCl solutions, activity in the chlorine and oxygen evolution reaction, impedance behavior in H2SO4, and stability during electrolysis in dilute chloride solutions, were investigated. The performances of the anodes are compared to those of a Ti/RuO2 anode prepared by the sol-gel procedure from an oxide sol obtained by the forced hydrolysis of ruthenium chloride in acid solution. The anodes prepared via the alkoxide route showed a higher capacitance and activity for the chlorine evolution reaction than the anode prepared by the inorganic sol-gel procedure. The results of the stability test showed that the utilization of the coating active material is better when the anodes were prepared via the alkoxide route than via the inorganic sol-gel procedure, particularly for anodes with a smaller mass of coating. The different rates of loss of activity indicate a degradation mechanism for the anodes prepared via the alkoxide route in which electrochemical dissolution of RuO2 from the coating surface prevails over the growth of an insulating TiO2 layer in the coating/Ti substrate interphase. The effect of RuO2 dissolution from the coating surface increases with increasing coating mass.

AB  - Electrocatalytic properties of RuO 2 /Ti anode with different coating masses, which are prepared by the alkoxide sol–gel procedure, are investigated in chlorine and oxygen evolution reactions by polarization measurements and electrochemical impedance spectroscopy in H 2 SO 4 and NaCl electrolytes. According to polarization measurements, the activity of anodes at overpotentials below 100 mV is independent of coating mass. However, impedance measurements above 100 mV reveal changes in the activity of anodes in chlorine evolution reaction for different coating masses. The diffusion limitations related to the evolved chlorine are registered in low-frequency domain at 1.10 V (SCE), diminishing with the increase in potential to the 1.15 V (SCE). The observed impedance behavior is discussed with respect to the activity model for activated titanium anodes in chlorine evolution reaction involving formation of gas channels within porous coating structure. Gas channels enhance the mass transfer rate similarly to the forced convection, which also increases the activity of anode. This is more pronounced for the anode of greater coating mass due to its more compact surface structure. The more compact structure appears to be beneficial for gas channels formation.

AB  - Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (PGME) was synthesized by suspension copolymerization and modified by ring-opening reaction of the pendant epoxy groups with ethylene diamine (EDA). Inverse gas chromatography (IGC) at infinite dilution was applied to determine the thermodynamic interactions of PGME and modified copolymer, PGME-en. The specific surface areas of the initial and modified copolymer samples were determined by the BET method, from low-temperature nitrogen adsorption isotherms. The specific retention volumes, Vg, of 10 organic compounds of different chemical nature and polarity (nonpolar, donor, or acceptor) were determined in the temperature range 333-413 K. The weight fraction activity coefficients of test sorbates, ohm(infinity)(1), and Flory-Huggins interaction parameters, chi(infinity)(12), were calculated and discussed in terms of interactions of sorbates with PGME and PGME-en. Also, the partial molar free energy, Delta G(1)(S), partial molar heat of mixing, Delta H-1(infinity), sorption molar free energy, Delta G(1)(S), sorption enthalpy Delta H-1(S), and sorption entropy, Delta S-S(1), were calculated. Glass transitions in PGME and PGME-en, determined from IGC data, were observed in the temperature range 373-393 K and 363-373 K, respectively.

AB  - Inverse gas chromatography under finite surface coverage conditions (IGC-FC) was used for the investigation of sorption of hexane, benzene, chloroform and tetrahydrofuran on macroporous crosslinked poly[(glycidyl methacrylate)-co-(ethylene glycol dimethacrylate)], poly(GMA-co-EGDMA), and copolymer modified with ethylene diamine, EDA, poly(GMA-co-EGDMA)-en, in the temperature range 333-363 K. Two poly(GMA-co-EGDMA) samples with different porosity parameters were synthesized by suspension copolymerization and modified using a ring-opening reaction of the pendant epoxy groups with EDA. The specific surface areas of the initial and modified copolymer samples were determined by the BET method from low temperature nitro- gen adsorption isotherms (77 K). The adsorption isotherms determined from chromatographic peaks of adsorbates were analyzed using the BET theoretical model and used for estimation of the surface area, isosteric heat of adsorption and the adsorption energy distribution on the surface of the initial and modified copolymer samples. It was observed that the adsorbate nature and the properties of the solid surface of the initial and modified copolymer governed the uptake of adsorbate by the copolymer. The deviations observed for the Sa values obtained by the BET method from the low temperature nitrogen adsorption isotherms and hexane was attributed not only to the difference in molecule size, but also to the specific polymer-adsorbate interactions. The isosteric heat of adsorption approached a constant value with increasing adsorbate loading. A large variation in the shapes of the q(st)-alpha curves resulted from strong acid-base interactions, as well as dissolution phenomena. Of the four studied adsorbates, chloroform was shown to have the greatest affinity towards the surface of the investigated polymer samples.

AB  - The morphology and the capacitive properties of carbon supported hydrous ruthenium oxide (RuOxHy/C), prepared by impregnation of low-surface area carbon black Vulcano (R) XC-72 R with solid phase of RuOxHy sol, were investigated by scanning electron microscopy, cyclic voltammetry and electrochemical impedance spectroscopy. The oxide sols of different ageing times, prepared by forced hydrolysis of RuCl3, were used for composite preparation. The prepared composites show considerably higher capacitance values in acid electrolyte if compared to carbon black support. Microscopic investigations show that the extent of impregnation and the composite surface appearance depend on ageing time. The composite capacitance increases with ageing time of oxide sol. A gradual decrease in capacitance of thermally untreated composite with charging/discharging cycles was registered, which appears to be related to the extent of impregnation, too. Electrochemical impedance spectroscopy measurements indicate an in-depth capacitance distribution through the composite layer. It was found that Nafion (R) layer, used to ensure the adhesion of the composite layer to the current collector, influenced the composite impedance behavior, especially on the oxide-rich parts of the composite surface.

AB  - Using a sol-gel procedure, RuO2-TiO2 active coatings were formed on a titanium support. The conditions of preparation of the RuO2 and TiO2 sols were investigated and the sols were characterized by transmission electron microscopy (TEM) and X-ray diffraction technique. Prepared anodes were investigated from the standpoint of morphology (scanning tunneling and electron microscopy) and electrochemical behavior (cyclic voltammetry, polarization measurements, and electrochemical impedance spectroscopy). The service life of the RuO2-TiO2 active coatings was examined by an accelerated corrosion stability test in 0.5 mol dm(-3) NaCl solution. In order to resolve the role of TiO2 in the deactivation mechanism of the active coating, additional TiO2 layers were introduced in the support/coating interface or on the surface of the coating. The behavior of these anodes with the TiO2-enriched coating layer was compared with the behavior of anodes with regular RuO2-TiO2 coatings. The results show that the loss of coating electrocatalytic activity is caused by dissolution of active Ru species and TiO2 enrichment in the coating. It is also observed that the sol-gel preparation procedure favors the formation of the TiO2 layer at the surface of the RuO2-TiO2 coating.

AB  - The deactivation process that leads to the end of titanium supported RuO2-TiO2 coating service life, for anodes prepared from RuO2 and TiO2 sols, as well as by the conventional thermal decomposition of RuCl3 and TiCl3, was investigated. The loss of electrocatalytic activity was registered by an accelerated stability test in 0.50 mol dm(-3) NaCl electrolyte, while the changes in the electrochemical properties were monitored during the stability test by cyclic voltammetry, polarization measurements and electrochemical impedance spectroscopy in 1.0 mol dm(-3) HClO4 and in 0.50 mol dm(-3) NaCl. The changes in anode behavior suggest that the essential cause for the deactivation of the anode prepared by the sol-gel procedure is the formation of an insulating TiO2-rich layer at the coating surface due to the continuous dissolution of the Ru active species. However, the growth of the insulating TiO2 layer in the coating/Ti substrate interphase mainly causes deactivation of the thermally prepared anode. The deactivation mechanism appeared to be the consequence of the different morphology of the coatings prepared by two different procedures.

AB  - The Point of zero charge of chromium(Ill)-oxide (pH(pzc)) was investigated by a batch equilibration method. The effect of several background electrolytes, in the concentration range of 10(-5)-10(-1) mol/dm(3), on pH(pzc) was established. In the absence of ionic species with specific affinity toward chromium(III)-oxide surface, the pH(pzc) for this material occurs at pH=6.7. KCl was found to behave as an indifferent electrolyte in the studied range of concentrations. A negligible increase in pH(pzc) due to the sorption of [Fe(CN)(6)](3-) ions was observed when K-3[Fe(CN)(6)] was used as an electrolyte. The presence of oxygen bearing electrolytes (KNO3, NaNO3, and K2SO4) shifts the pH(pzc) toward lower values. In the case of highly hydrolyzable cation Cd2+, the pH(pzc) decreases even more and the buffering effect of chromium(Ill)-oxide is changed.

AB  - Colloidal particles of chromia have been prepared by forced hydrolysis of an aqueous solution containing chromium chloride hexahydrate. At elevated temperature, a controlled addition of potassium hydroxide yielded colloidal chromia particles. After the sol coagulation, amorphous dried residues (I) were converted to crystalline form (II) by heating at 1073 K. The thermal treatment was also accompanied by a reduction in both surface area (from 75 to 9 m(2)/g) and point of zero charge (pH(pzc); from 4.7 to 4.0). Chromia dissolution over the studied pH range (pH = 2-12) exhibits a parabolic trend, with minimum solubility at pH(pzc).

AB  - Preparation of RuOxHy/carbon black nanocomposite material was performed by the impregnation method starting from RuOxHy sol as a precursor. Black Pearls 2000(R) (BP) and Vulcan(R) XC-72 R (XC) were used as supporting materials. Samples of the composite were calcined in nitrogen atmosphere at temperatures from 130 to 450 degreesC. Chemical and structural characterization of the precursor and the composites was performed by using energy-dispersive X-ray fluorescence spectroscopy (EDXRFS), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). These techniques showed that the oxide impregnated into carbon support is hydrous and amorphous. The amorphous structure is maintained if the composite is calcined up to 300 degreesC, while the lowintensity peak at 2theta position that corresponds to the most intensive peak of the rutile structure was registered at 450 degreesC. The capacitance of the composite was determined using cyclic voltammetry. It was found that the capacitance is dependent on calcination temperature and surface area of the carbon black support. The highest specific capacitance of about 700 F g(-1) of composite was registered for RuOxHy supported on BP and calcined at 300 degreesC while four times lower values was obtained for RuOxHy supported on XC. The capacitance measurements indicated that XC-supported RuOXHy composite is highly porous while BP-supported one is more compact.

AB  - In order to understand the role of TiO2 in the deactivation mechanism of an active RuO2–TiO2 coating, an additional TiO2 layer was introduced in the support coating interphase of regular Ti//[RuO2–TiO2 anode in one case and on the surface of the coating in the other. The electrochemical behavior of these, with TiO2 enriched, anodes was compared with the behavior of anodes with regular RuO2–TiO2 coatings, which were subjected to an accelerated stability test. A high-frequency semicircle in the complex plane plot obtained by electrochemical impedance spectroscopy, for a regular RuO2–TiO2 coating corresponds to TiO2 enrichment in the coating as a consequence of anode corrosion. In the case of the coatings with additional TiO2 layers, a high-frequency semicircle was not observed. The additional TiO2 layers increase the coating overall resistance and influence the coating impedance behavior at low frequencies. Similar equivalent electrical circuits were used to analyze the impedance behavior of coatings having an additional TiO2 layer at different position within RuO2–TiO2 coating.
AB  - U cilju ispitivanja uloge titan-oksida u deaktivaciji RuO2–TiO2 prevlake na titanskoj podlozi, ispitivane su osobine anoda sa dodatnim slojem TiO2 u međufazi podloga prevlaka, odnosno na površini prevlake. Elektrohemijsko ponašanje ovih upoređeno je sa ponašanjem anoda sa uobičajenom RuO2–TiO2 prevlakom, kao i sa onima koje su bile podvrgnute ubrzanom testu stabilnosti. Pojava polukruga u visoko-frekventnoj oblasti u dijagramima u kompleksnoj ravni, koja je registrovana spektroskopijom elektrohemijske impedancije za uobičajene RuO2–TiO2 prevlake, a koja je posledica obogaćivanja prevlake sa TiO2 tokom njene deaktivacije, nije uočena kod anoda sa dodatim TiO2 slojem. Dodati TiO2 slojevi povećavaju omsku otpornost prevlake i utiču na impedancijsko ponašanje pri niskim frekvencijama. Za analizu impedancijskog ponašanja prevlaka sa dodatim TiO2 slojevima kao i uobičajenih RuO2–TiO2 prevlaka koje su deaktivirane korišćena su slična ekvivalentna električna kola.

AB  - In this paper surface properties of calcium-hydroxyapatite, synthesized by modified hydrothermal reaction of urea and Ca(EDTA)(2-) in phosphate solutions, as well as the dependence of calcium hydroxyapatite dispersion stability on pH were determined. The specific surface area of calcium-hydroxyapatite was experimentally found to be 67 m(2)/g. The point of zero charge (PZC) of indifferent KCl electrolyte of 6.8 +/- 0.1 was determined by the batch equilibration method. From the dependence of surface charge density on pH and electrolyte concentration, the intrinsic equilibrium constant of surface groups p K-a2(int) was determined to be 8.3 +/- 0.1, while p K-a1(int) calculated from the pK(a2)(int) and point of zero charge values, is 5.3 +/- 0.1. Hydroxyapatite suspension stability was investigated, in the pH range from 7 to 12, it was revealed that the most stable dispersion at pH 10.
