  • 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
    • 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.

  • Study of the sorption of synthetic dyes from aqueous solution onto
           cellulosic modified polymer
    • Abstract: Abstract The ability of cyclodextrins to facilitate inclusion of chemical molecules can be exploited to obtain new adsorbent materials for organic pollutants removal such as synthetic dyes from wastewater. In this work we report a study on the formation of the complex acrylamidomethylated-β-cyclodextrin, then on the grafting on cellulosic polymer. The grafting is initiated by ceric ions Ce (IV) and confirmed by infrared analysis (FTIR). Scanning electron microscopy (SEM) analysis was carried out to evaluate properties of structure and surface of grafted polymers. The experiments of balance adsorption of reactive, acid, and cationic dyes were made in aqueous solutions for 24 h at pH: 3, 6 and 11. Our results indicate formation of a permanent chemical bond between β-cyclodextrin and polymer materials. The cellulosic polymers can effectively be modified without significant change in the structural properties. In addition, absorption tests showed that the grafted functions clearly improve retention of liquids by cellulose. The results of dye adsorption in aqueous medium show the ability of modified polymer to fix organic dyes, and to be used in the industrial liquid waste processing. Differences in adsorption capacities may be due to the effect of dye structure.

  • Removal of Cr(VI) from aqueous solutions by calcined Zn/Al- and
    • Abstract: Abstract The paper has investigated sorption of Cr(VI) from aqueous solutions by calcined forms of Zn/Al- and Mg/Fe-hydrotalcites. We have determined the impact of sulfate-, hydrocarbonate- and nitrate-ions on the degree of removal of Cr(VI) from aqueous solutions. The most effective removal of chromate-ions from aqueous solution by calcined forms of hydrotalcites is observed in an acid and weakly acid region of the pH: at an increase of the pH from 4 to 8 the adsorption values decrease by ∼ 6–7%.

  • Influence of the concentration of fluorine ions and clayey particles on
           the efficiency of aluminum coagulants in defluorination of water
    • Abstract: Abstract The paper has investigated the influence of the initial concentration of fluorine ions (2.0–8.5 mg/dm3) on the efficiency of sulfate (SA), basic sulfate (OSA 2.0) and basic aluminum chloride (5/6 OXA) in defluorination of water. It has been established that replacement of aluminum sulfate by its basic salts makes it possible not only to reduce consumption of the coagulant, but also provides a possibility to clean waters polluted with fluorine ions by 27–35% without additional introduction of alkaline agents. The paper has shown good promises in using OSA 2.0 for defluorination of low turbidity waters (underground sources), while 5/6 OXA—for water with relatively high contents of suspended impurities.

  • 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.

  • Highly-effective liquid chromatographic determination of
           2,4,6-trinitrophenol in surface waters after its selective solid phase
    • Abstract: Abstract The paper has proposed a new adsorbent for solid-phase extraction concentration of 2,4,6-trinitriphenol from aqueous objects of the environment followed by its determination in the concentrate by the method of highly performance liquid chromatography (HPLC). Silica modified by N-epoxypropylcarbazol was used as solid-phase extragent, which in the pH 1.5 ± 2.5 interval extracts up to 98% of the matter being analyzed. Sorbent capacity in terms of 2,4,6-trinitrophenol in the Henry area constitutes 5.3 mg/g, distribution coefficients reach values 7.9 × 104 cm3/g. Nitrophenols are quantitatively eluted in dimethyl sulfoxide, which makes it possible to determine them by the HPLC with a diode array detector at the level 18 μ/dm3.

  • Development of the zeolite-sorption process for electroplating wastewater
    • Abstract: Abstract Regularities of the sorption of heavy metal ions on the natural zeolite (calcium heulandite) have been investigated. Relationships of the sorption of heavy metal ions as a function of the fraction size of test zeolites were obtained. The sorption values in static conditions for nickel, copper and zinc ions amounted to 5.9, 4.8 and 2.7 mg/g, respectively, making it possible to use zeolites as sorbents in the treatment of wastewater from electroplating facilities. The degree of wastewater purification in a filter with calcium heulandite medium amounted to ∼ 90%.
