Streszczenie:
The comparative experiments for removing humic acid as environmental pollutant were conducted by adsorption on iron oxide, photooxidation in the presence of titanium dioxide catalyst and combined adsorption-photooxidation by iron-titanium mixed metal oxides, where all these active components were immobilized on polypropylene granules. The main purpose of the work was the combination of adsorption and photocatalytic oxidation processes to remove humic acid. The granules with iron-titanium mixed oxide for treating humic acid gave much better results with 1.2~3 times higher removal rates comparing to the other two single coated oxides at certain pH values. And the order of removal efficiency according to pH was the same as for single iron oxide-coated granules. The ratio 1:2 of iron oxide/titanium dioxide was found optimal for maximal decolorization of humic acid solution. The total organic carbon decrease of humic acid in each experiments, when it was pre-equilibrated with mixed oxides-coated granules in the dark for 30 min and without pre-equilibration, was very similar. The results suggested that the mechanism of humic acid removal may be not only a respectively combined adsorption and photooxidation by iron oxide and titanium oxides, but an enhanced photooxidation reaction as a result of concentrating humic acid on titanium oxide surface by iron oxide.

Abstract. Iron dissolution from mineral dusts and soil particles is vital as a source of bioavailable iron in various environmental media. In this work, the dissolution of iron oxide particles trapped in ice was investigated as a~new pathway of iron supply. The dissolution experiments were carried out in the absence and presence of various organic complexing ligands under dark condition. In acidic pH conditions (pH 2, 3, and 4), the dissolution of iron oxides was greatly enhanced in the ice phase compared to that in water. The dissolved iron was mainly in the ferric form, which indicates that the dissolution is not a reductive process. The extent of dissolved iron was greatly affected by the kind of organic complexing ligands and the type of iron oxides. The iron dissolution was most pronounced with high surface area iron oxides and in the presence of strong iron binding ligands. The enhanced dissolution of iron oxides in ice is mainly ascribed to the "freeze concentration effect", which concentrates iron oxide particles, organic ligands, and protons in the liquid-like ice grain boundary region and accelerates the dissolution of iron oxides. The ice-enhanced dissolution effect gradually decreased when decreasing the freezing temperature from −10 °C to −196 °C, which implies that the presence and formation of the liquid-like ice grain boundary region play a critical role. The proposed phenomenon of enhanced dissolution of iron oxides in ice may provide a new pathway of bioavailable iron production. The frozen atmospheric ice with iron-containing dust particles in the upper atmosphere thaws upon descending and may provide bioavailable iron upon deposition onto the ocean surface.

Streszczenie:
Iron (III) oxide, (Fe2O3, nr CAS 1309-37-1) in natural conditions occurs as iron ore. The most common (hematite) contains about 70% pure iron. Iron (III) oxide is used as a red dye in ceramics, glass and paper industries and as a raw material for abrasive metalworking (cutting). Iron (II) oxide, (FeO, CAS 1345-25-1) occurs as a mineral wurtzite and is used as a black dye in cosmetics and as a component of tattoo ink. Iron (II) iron (III) oxide (Fe3O4, CAS 1309-38-2; 1317- -61-9) is a common mineral. It has strong magnetic properties (so called magnetite). It occurs in igneous rocks (gabbro, basalt). It is the richest and the best iron ore for industry. Occupational exposure to iron oxides occurs in the mining and metallurgical industry in the production of iron, steel and its products. Welders, locksmiths, lathes and workers employed in milling ores and polishing silver are exposed to iron oxides. According to data from the State Sanitary Inspection, in 2013, 389 people in Poland were exposed to iron oxide in concentrations exceeding the current NDS (5 mg/m3) and in 2014 – 172 people. After single and multiple intratracheal and inhalation exposure of animals, transient intensification of oxidative stress and inflammatory reactions were reported. Iron (III) oxide did not cause genotoxic and carcinogenic effects. In literature, there are no data on its effects on fertility, reproduction and pregnancy. Data on chronic toxicity of iron oxides for humans exposed in working environment are limited. In epidemiological studies, all information presented in the documentation comes from observations of people exposed to the combined effects of iron oxides and other factors. It is not stated whether occupational exposure was related to the specific iron oxide and to what concentrations workers were exposed. The most commonly encountered toxic effect in the occupational exposure of iron ore miners and iron welders and welders was minor lung fibrosis lesions and iron-silicon dust (as seen in the RTG study). Siderose is the occupational disease of miners and iron ore metallurgists. Moreover, cases of lung cancer have been reported in miners, steel workers and welders, but they were caused by total exposure to other compounds, including radioactive radon, carcinogenic chromium, manganese, nickel, other oxides (SiO2, ZnO, CO, NO, NO2, MgO) as well as exhaust gases from diesel engines. According to IARC, iron (III) oxide belongs to group 3 (cannot be classified as carcinogenic to humans). Iron (III) oxides can accumulate in a lung tissue, this process may be responsible for the occurrence of fibrosis sites, particularly in higher parts of external lung parts. These effects were visible in the X-ray examination only. Pneumoconiosis (siderosis) caused by exposure to iron oxides is usually asymptomatic (lack of clinical symptoms and changes in lung function parameters). The basis for the proposed MAC-TWA value for inhalable iron oxide fraction was NOAEL of 10 mg Fe/m3. People exposed for more than 10 years to iron (III) oxide had no pulmonary changes. After application of an uncertainty factor of 2 (for differences in personal sensitivity in humans), the MAC-TWA value for the iron oxide fraction was proposed at 5 mg/m3 (calculated as Fe). The same observations on humans were the basis for calculating the MAC-TWA value for respirable fraction of iron (III) oxide. On 12% of workers exposed to respirable fraction at mean concentrations of 10 ÷ 15 mg/m3, changes in pulmonary X-ray were observed. The value of 10 mg/m3 was assumed as LOAEL. After applying the appropriate uncertainty coefficients, the MAC-TWA value for the iron oxide respirable fraction was proposed at 2.5 mg/m3. The authors propose to leave the short-term value (STEL) of 10 mg/m3 for inhaled fraction for iron oxides and to introduce STEL value of 5 mg/m3 for respirable fraction. It is recommended to label the substances with "I" - irritant substance.

The object of research is the state of equilibrium of ferrum(II) and ferrum(III) oxides in glass melts at temperatures of 1000–1400 °С, welded in oxidizing, neutral and reducing conditions with a content of ferrum oxides up to 1.5 %. This problem is relevant in the following aspects. The first aspect of this problem is the unwanted coloring of the glass: FeO colors the glass blue, and Fe2O3 – yellow. The combined presence of ferrum(II) oxide and ferrum(III) oxide determines the gradations of glass shades that fall on the green spectrum. The second aspect concerns the thermophysics of processes of boiling glasses containing iron oxides. Ferrum(II) oxide causes a strong absorption band of infrared radiation in the region of 1.1 μm. This becomes an obstacle to the volumetric heating of glass in the processes of cooking, forming, and annealing. The third aspect of the problem concerns the structure of glasses and glass-crystalline materials with an increased content of iron oxides. Iron oxides significantly affect the processes of glass structuring, as ferrum(III) oxide is a typical network former, and ferrum(II) oxide is a typical modifier. The state of FeO↔Fe2O3 equilibrium in glass is significantly influenced by the glass cooking environment, the total amount of iron oxides, and the temperature of the melt. The glass brewing environment has the greatest influence on the balance of iron oxides in the glass. The share of FeO oxide in the total amount of iron oxides (FeO+Fe2O3) increases sharply when moving from an oxidizing medium to a neutral one and then to a reducing one. During thermostating at a temperature of 1400 °С, the proportion of FeO in the glass increases by 1.4–1.7 times during cooking in an oxidizing environment, by 1.2–1.3 times in a neutral environment, and by approximately 1.1 times in a reducing environment. At the same time, this growth is more noticeable in glasses with a lower iron content. Thus, the equilibrium state of FeO↔Fe2O3 in glass significantly affects the technological and operational properties of silicate melts and the final glass. The ratio of formed oxides of trivalent and divalent ferrum was studied by chemical (titrometric) analysis. The research results can be used in practice to develop the composition of glasses with an increased content of iron oxides.

In contrast to other third-body layers – such as water, oil, sand, and leaves – iron oxides exert a constant influence on the friction and wear of wheel–rail contact. However, studies that focus on the influence of iron oxides have not been conducted systematically until the 21st century. This study is a comprehensive presentation of early and recent research works related to the influence of iron oxides on the wheel–rail contact. The characteristics of iron oxides in general and those between railway wheels and rails are discussed. A comparison of various laboratory tests and their relation to actual conditions is also presented. The authors find that the influence of various types of iron oxides on friction and adhesion differs. The thickness of the iron oxide layer also affects the friction and wear. However, the results obtained from laboratory rigs differ from those obtained in field testing. Therefore, it is critical to formulate a standard procedure that produces iron oxides that are similar to those observed in the field. Compared to the case of wheel–rail friction and adhesion, the influence of iron oxides on wear is not so well investigated. Thus, further research in those areas is warranted.

Abstract This study was conducted to investigating the behavior of free iron oxides in some soil orders in Iraq. Soil samples were collected from five Pedons for soil orders Entisols, Aridisols, Inceptisols, Vertisols and Mollisols. Total free iron oxides (Fed) were extracted by CBD, amorphous iron oxides by acid ammonium oxalate and iron oxide linked with organic matter by alkaline Sodium pyrophosphate. the distribution of iron oxides in (Fep) to crystallized iron oxides were compared. The results showed that (Fed-Feo) there is no particular direction that controls the vertical distribution of Fed Mollisols and Vertisols pedons excelled in the content of Fed compared to the other orders. Amorphous Feo accumulates in surface horizons and Mollisols pedon was excelled on all pedons in Feo content followed by Vertisols, Inceptisols, Aridisols and Entisols. The Pedons of Inceptisols, Aridisols and Entisols soil order contain higher amounts of crystalline Fed-O oxides compared to the Mollisols and Vertisols as well the vertical distribution taken a different pattern for all pedons. (Fep) was low compared to other forms of iron oxides and is accumulated in surface soil horizon in all pedons.

This work focused on the synthesis of iron oxide nanoparticles by the coprecipitation method with three basic solutions, namely, NH4OH, KOH, and NaOH. The synthesized iron oxides were characterized by various techniques such as XRD, MET, BET, and a SQUID magnetometer. The results showed nanosized particles of 13.2, 9.17, and 8.42 nm and different phases associated to maghemite and maghemite/hematite. The surface areas were 113, 94, and 84 m2/g and the magnetization strength were 58, 61, and 75 emu/g to iron oxides synthesized with NaOH, KOH, and NH4OH, respectively. The magnetic iron oxides obtained using NaOH were more efficient in the removal of lead and arsenic by adsorption than iron oxides obtained with KOH and NH4OH. However, the magnetic strength decreases using NaOH and KOH. The highest adsorption capacities attained for lead and arsenic removal were 16.6 and 14 mg/g, respectively, using NaOH-based iron oxides.

Streszczenie:
The iron content of industrial minerals can be reduced by physical and chemical processing. Chemical processing is very efficient to achieve a high degree of iron removal at minimum operating cost. Both inorganic acids and organic acids have been used for clay refining. However, due to environmental pollution and contamination of products with the SO42- and Cl-, inorganic acids should be avoided as much as possible. This research investigated the use of oxalic acid to dissolve iron oxides and the dissolution characteristics of natural iron oxides. The dissolution of iron oxides in oxalic acid was found to be very slow at temperatures ranging from 25??? to 60???, but increased rapidly at a temperature above 90oC with increasing oxalic acid concentration, whereas the pH caused the reaction rate to decrease at pH>2.5 and improved the rate from pH 1 to pH 2.5. The iron oxides such as goethite (??-FeOOH), lepidocrocite (??-FeOOH) and iron hydroxide (Fe(OH)3) can be dissolved faster at the presence of magnetite which exhibits an induction period at the initial stage and showed the bell-shaped curves for the dissolution. In titration tests, however, the increase of temperature causes an increase in solubility of the oxalate complexes, resulting in an increased stability of ionized species in solution. During the addition of NaOH, NaHC2O4???H2O was precipitated without forming Na2C2O4???H2O, but it was re-dissolved at pH>4.0. On the other hand with NH4OH, NH4HC2O4???H2O and (NH4) 2C2O4???H2O co-precipitated at pH 0.93, but also re-dissolved at over pH 2.03. The reaction temperature was found not to affect the removal of iron from the ferric oxalate complex solution using lime. Iron is removed as iron hydroxide and calcium oxalate is then precipitated during the iron removal step. The formation of Fe(OH)3 in the solution was affected by the dissociation of Ca(OH)2. The thermodynamics of sodium, ammonium and iron oxalate complexes were investigated and the standard free energy, ??Go was calculated using thermodynamic data and solubility products. The dissolution of pure hematite by oxalate was found to follow a shrinking core model of which the kinetic step of the reaction is the controlled mechanism.

A suite of well-characterized synthetic microcrystalline hematite samples, 2-line and 6-line ferrihydrite samples and nanohematite samples are studied through magnetization-field curves measured at room temperature. The single-domain microcrystalline hematite samples are analyzed through basic hysteresis parameters providing sample characteristics such as magnetic anisotropy information, the effect of annealing on the origin of the magnetization and the relatively constant intrinsic high field susceptibility. The application of a magnetic granulometry method on the magnetic data of the superparamagnetic nanohematite and ferrihydrite samples provides fundamental information such as the intrinsic mass magnetization and estimated particle size. Additionally, it gives insight into possible moment formation mechanisms within the superparamagnetic particles. The observed differences between the magnetic properties of the magnetically blocked and the superparamagnetic samples considered are also discussed.

Streszczenie:
The problem to refine high-chromium cast iron melts obtained with the use of a large proportion of scraped metal and scrap is considered herein. Since fluxes containing calcium fluoride are currently considered to be environmentally polluting, it is required to reduce the use of fluorides, or completely replace them. It was shown that a decrease in the melting point of the flux can be achieved with the use of a mixture of calcium and magnesium fluorides or by the introduction of boron oxide into the composition of the fluxes. However, the efficiency of these fluxes, as well as silicocalcium additives and vacuum remelting in the high-chromium cast iron melting when a high proportion of scrap in the charge is used, has not been previously considered. In this regard, the effect of these refining methods on the removal of non-metallic inclusions in high-chromium cast iron of Grade 340Х18HML was experimentally assessed. Thermodynamic calculations were performed for the interaction of magnesium and calcium fluorides with non-metallic oxide inclusions typical of high-chromium cast irons and with oxides used for neutral lining of induction furnaces. It has been shown that fluxes based on boron oxide, magnesium and calcium fluorides and their mixtures effectively remove oxide and sulfide non-metallic inclusions; however, they have a destructive effect on the lining of furnaces, significantly reducing its service life. The addition of silicocalcium reduces the content of sulfides but does not affect the content of non-metallic inclusions in the form of oxides and nitrides. Vacuum remelting effectively reduces the number of nitride inclusions.

Streszczenie:
Various transition metal oxide nanostructures are synthesized using a novel probe-flame interaction method. An opposed flow flame of methane and oxygen enriched air provides a high-temperature reacting environment forming various metal oxide structures directly on the surface of pure metal probes. The unique thermal profile and chemical composition of the generated flame tends to convert almost pure bulk (99.9%) metallic materials into 1-D and 3-D structures of different chemical compositions and unique morphologies. The synthesized molybdenum, tungsten, and iron oxide structures exhibit unique morphological characteristics. The application of Mo probes results in the formation of micron size hollow and non-hollow Mo-oxide channels and elongated structures with cylindrical shapes. The use of W probes results in the synthesis of 1-D carbon-oxide nanowires, 3-D structures with rectangular shapes, and thin oxide plates with large surface areas. The formation of elongated iron-oxide nanorods is observed on iron probes. The iron nanorods’ diameters range from ten nanometers to one hundred nanometers with lengths of a few micrometers. Flame position, probe diameter, and flame exposure time tend to play an important role for material shape and selectivity.
