  • Water and other substances, which expand upon solidification
    • Abstract: Abstract The article has considered physical and crystallographic properties of substances, which expand in crystallization. It has also proposed explanation of manifestation of these properties in the formation of the crystalline lattice of a special type—hexagonal, cubic or tetrahedral with corresponding changes of the length and angles of interatomic and intermolecular bonds. The hexaoctahedral structure of crystals for such substances is the most characteristic. An assumption was expressed that existing impurities in the form of HDO and others may serve as seeding or stabilizers of certain crystalline structures.

  • Removal and inactivation of virus by drinking water treatment in the
           presence of bromide or iodide
    • Abstract: Abstract The inactivation of virus in raw water was conducted in a continuous flow pilot scale system. Coliphage MS2 was used as model organism for human enteric virus. The effect of disinfection technologies (single or combined process of ozonation and chlorination) and interfering substances (bromide or iodide) on inactivation of virus, and the removal performance of virus in raw water by the pilot scale system (Train A and B) were investigated. The results indicated that bromide or iodide in water was detrimental to ozonation but beneficial to chlorination for virus inactivation. After bromide or iodide was added, the removal of MS2 by ozonation unit was much lower than before (p < 0.01), the removal of MS2 by chlorination unit was significantly higher than before (p < 0.05). Both Train A and B could remove and inactivate MS2 in raw water completely even at high concentration of bromide (675.24 μg/dm3) and iodide (52.33 μg/dm3). The processes of Train A and B can effectively guarantee the virological safety of drinking water.

  • Modeling processes of sorption of U(VI) based on regularities of kinetics
           of reactions in solutions
    • Abstract: Abstract The article has investigated sorption of U(VI) by layered zinc and aluminum hydroxides containing in the interlayer space ions of carbonate or diethylenetriamine pentaaceatate. It has been found that absorption rate of U(VI) is proportional to its concentration in the solution and the content of free active centers of the sorbent. The rate constant at 20°C referred to concentrations in the solution of U(VI) and active centers of investigated sorbents constitute respectively 163 and 238 M−1 · min−1. The proposed method of studying sorption kinetics is compared with the known concept of reactions of the pseudo second order.

  • Dispersive liquid-phase microextraction for determination of phthalates in
           water
    • Abstract: Abstract A technique for phthalate extraction from water samples has been proposed. This technique is based on the preconcentration of target substances using the dispersive liquid-phase microextraction with subsequent determination of these substances using a gas chromatograph with flame ionization detector. Under the optimal conditions of microextraction (involving 0.25 cm3 of acetonitrile and 0.05 cm3 of chloroform in 10% NaCl solution for water sample volume of 8 cm3) concentration factors of phthalates amount to 360–393 at their extraction degree of 91–98%, while the detection limit can reach 3–8 μg/dm3. The proposed technique is characterized by a high accuracy and reproducibility.

  • Impact of surface properties of hydrated compounds based on ZrO 2 on the
           value of ionic conduction
    • Abstract: Abstract We have measured the maximum ionic conduction in distilled water of hydrated compounds based on ZrO2 containing as the second component zirconium phosphate, zirconium phosphomolybdenum acid as well as hydrated aluminum oxide in a maximum saturated form after absorption of Cu(II) ions. The conduction value of ion-exchange materials constitutes 0.01–0.07 S · m−1. Compared were the values of ionic conduction as well as migration mobility of adsorbed Cu(II) ions with properties of the surface of hydrated compounds (charge, volume of pores, radius of pores). It was shown that ionic conduction and mobility of adsorbed ions increase with a decrease of the radius of pores of inorganic polymers.

  • Monitoring of aerosols and the state of sea water of the water area of the
           Karadag natural reserve
    • Abstract: Abstract The article sets out results of two-year research of dispersion characteristics and the degree of pollution with heavy metals of atmospheric aerosols and total toxicity of sea water of the water area of the Karadag natural reserve. The statistical analysis of dispersion characteristics of aerosol particles showed that atmospheric aerosols in the region under study are polydisperse. Average disperse aerosols prevail and the quantity of them diminishes as their diameter increases. Complex research of the sea water toxicity showed some improvement of the ecological state of the water area of the reserve (inn respect to 2010–2011).

  • Nitrate-containing brackish water treatment with the obtaining of ammonium
           fertilizers by electrodialysis
    • Abstract: Abstract The effective purification of brackish waters of nitrates has been shown to be possible by using a special design electrodialyzer with simultaneous high concentration in a brine chamber of salts NH4NO3, NH4Cl and (NH4)2SO4 that are valuable mineral fertilizers. The brine concentration ratio increased with the rise of the current density and reached 60.0–70.6 g/dm3 under experimental conditions, while the total salt content of brine amounted to 136.7–162.5 g/dm3/ The efficiency of nitrate removal increased with the rising degree of desalination and amounted to 90% with the reduction of the total salt content of dialysate to 0.2 g/dm3.

  • Trilite adsorption characteristics for perchlorate from Korean military
           facilities
    • Abstract: Abstract Perchlorate is used as an oxidizer in solid propellants for rockets, missiles, and fireworks. It is not classified as a carcinogen according to the US EPA, EU, and WHO; however, it affects the respiratory system and skin. Perchlorate removal is not very effectively achieved by biological processes with coagulation and activated carbon. At present, relatively efficient removal methods, which have been tested and backed by study, include ion exchange and membrane processes. Ion exchange is the most commonly used method, and it has proven to be the most effective. The maximum perchlorate concentrations in Korea and USA were 107.7 μg/L and 2600 mg/L, respectively, exceeded the Drinking Water Equivalent Level (DWEL) by the US EPA (24.5 μg/L). The perchlorate removal method was tested using an isothermal adsorption experiment that determined the characteristics of perchlorate adsorption onto Trilite. Evaluation of these results suggests a potential for local application of Trilite for perchlorate removal. The parameters and coefficients for adsorption isotherms were determined with linear and non-linear regression methods. The coefficient of determination of the Langmuir-1 isotherm was the highest (R2 = 0.998), and the maximum adsorption was 145 mg/ml, which was higher than reported for other anion exchange resins. The non-linear regression analysis showed the highest coefficient of determination (R2 = 0.968) for both the Langmuir and Redlich-Peterson isotherms. The optimal adsorption isotherms with the non-linear regression method were the Langmuir and Redlich-Peterson isotherms. The potential for local application of Trilite was evaluated via the Langmuir isotherm, which has a relatively simple formula. The value of R s was 0.028 (between 0< R s ≪1) or “very favorable.” Therefore, Trilite appeared to be among the desirable alternatives for the effective removal of perchlorate.

  • Regional-ecological approach to the assessment of possible aftermath of
           pollution of water basin of the Kalmius River
    • Abstract: Abstract The article has investigated the ecological state of hydroecosystems of the water basin of Kalmius River (WBK). The investigations were carried out with the account of new information methods of monitoring over indicators and their parameters of the development of water ecosystems, which made it possible to understand causal connections in the system hydroecosystems—nature-anthropogenic water ecosystems—socio-economic systems. It has been shown that a self-reconstructive potential of WBK quantitatively agrees with the maximum technogenic load. Proposed methods of monitoring the ecological state of WBK made it possible to determine potentially possible causes of hydrosystem degradation.

  • Application potential of boron-selective sorbents of different nature for
           water conditioning in terms of the boron content
    • Abstract: Abstract Comparative investigations of water conditioning in terms of the boron content under dynamic conditions have been performed using synthetic organic sorbents (Amberlite IRA-743 and SB-1) and inorganic sorbent (hydrated zirconium dioxide). Sorbent Amberlite IRA-743 of N-methyl-glucamine type was shown to be the most promising for boron extraction and the disposal of regenerating solutions aimed at preventing their harmful effect on the environment. A significant rise of the efficiency of boron sorption from the real water of the Black Sea using this sorbent as compared to the boron sorption from the solution modeling the permeate of reverse osmosis plants has been detected that is determined by the salting-out effect of Mg2+ ions present in sea water on the sorption process.

  • Water and carbon dioxide as the main precursors of organic matter on Earth
           and in space
    • Abstract: Abstract The article considers possible ways of the origin of organic matter from inorganic components on the planetary and space scales. A special attention is given to practical possibility of the synthesis of organic acids, amino acids, nucleic bases from carbon dioxide and water under the effects of ultraviolet radiation under conditions of the Earth and other celestial bodies. The obtained data make it possible to put forward the concept of the origin of life in the Universe based on the presence in the outer space of water molecules, carbon dioxide and the external source of energy in the form of space radiation.

  • Removal of arsenic compounds from natural waters using a hybrid system
           (photocatalysis-reverse osmosis)
    • Abstract: Abstract The extraction process of As(III) and As(V) compounds from water using the reverse osmosis treatment with membrane ESPA-1 has been studied. The retention coefficient of As(III) was shown to amount to 47–56% in pH interval of 5.2–9.4; as a result, the arsenic concentration in permeate exceeds the drinking water MAC by about 5 times. A hybrid system (photocatalysis-reverse osmosis treatment) was proposed for the effective removal of arsenic compounds from natural waters.
