  • Self-organization through chaos: From lifeless matter to biologically
           intellectual creatures
    • Authors: V. V. Goncharuk
      Pages: 317 - 318
      Abstract: The essence of all chemical reactions running on Earth according to laws of non-equibrium thermodynamics of Prigogin consists of endless sequences of processes of self-organization. Thanks to it, new types of structures may emerge spontaneously characterized by the transfer from chaos and disorder to order and organization.

  • On the possibility of chiral structure-density submillimeter
           inhomogeneities existing in water
    • Authors: V. V. Goncharuk; A. V. Syroeshkin; T. V. Pleteneva; E. V. Uspenskaya; O. V. Levitskaya; V. A. Tverdislov
      Pages: 319 - 324
      Abstract: The existence of stable formations representing submillimeter density inhomogeneities in aqueous solutions was confirmed by using the laser light diffraction (LALLS) method and also the dynamic (DLS) and two-dimensional light scattering methods. The effect of low angle light scattering by giant water clusters depends on the presence of ions or dissolved substances in water solution, and also on the concentration of deuterium (heavy hydrogen isotope). It has been shown that the reduction of deuterium concentration results in the reduction of light scattering ability of protein nanoparticle preparations and water. The formation of long-living discrete water cluster structures possessing chiral properties was substantiated for explaining the manifestation of effects of weak impacts and low concentrations on biological objects.

  • Controlled chaos: Heterogeneous catalysis
    • Authors: V. V. Goncharuk; T. V. Pleteneva; E. V. Uspenskaya; A. V. Syroeshkin
      Pages: 325 - 330
      Abstract: A technique for controlling the catalytic process using the impact on heterogeneous catalyst capable of staying in at least two conformational states has been described. The distinctive feature of conformers is their topological difference in the region of space of no less than 1 nm3. Binding of ligands or the presence of high intensity electric field makes it possible to change in a specified way the catalyst affinity to reaction’s substrates/products.

  • Anomalous thermal properties of water
    • Authors: N. A. Mishchuk; V. V. Goncharuk
      Pages: 331 - 338
      Abstract: The relationships of coefficients of molecule diffusion, viscosity, thermal capacity, thermal conductivity and other properties of water as a function of temperature and pressure have been analyzed. It is shown that the main regularities of changes in water characteristics, including qualitative differences of its behavior from the rest of molecular liquids are stipulated by the peculiarities of covalent and hydrogen bonds.

  • Influence of the concentration of deuterium on structural changes of
           aqueous solutions
    • Authors: V. V. Goncharuk; M. D. Skilskaya; I. Yu. Romanyukina; A. I. Marinin; S. A. Dolenko
      Pages: 339 - 345
      Abstract: Using vacuum ultraviolet radiation, methods of dynamic and electroforethic light scattering had been studied the influence of the concentration of deuterium on structural changes of water. Experimentally it was established the sizes of optical heterogeneities of studied waters at different concentrations of deuterium. It is shown that concentration dependencies have a non-linear nature with extreme points at D/H = 200; 40000 and 90000 ppm, which may be conidered as critical characteristic of self-organizing systems. In these points the dynamics of the system undergoes qualitative restructuring going from one structural state to the other.

      Pages: 355 - 359
      Abstract: A technology of wastewater treatment from nonionic surfactants by their destruction in a plasma-chemical reactor has been proposed. The effect of peculiarities of chemical structure of different surfactants and the treatment duration on the degree of their decomposition in plasma flame is investigated. It is shown that the decomposition of these substances is a source of additional thermal energy released in the process of plasma-chemical oxidation of organic components of solution.

  • Aqueous solutions of humic acids as self-organizing dissipative systems
    • Authors: S. A. Dolenko; M. Yu. Trifonova; Yu. I. Tarasevich
      Pages: 360 - 367
      Abstract: The paper investigates the size, morphology and ζ-potential of particles, electrical conduction, and surface tension of aqueous solutions of humic acids as a function of their concentration, pH and time using the methods of dynamic and electrophoretic light scattering, transmission electron microscopy and tensiometry. It is shown that aqueous solutions of humic acids represent open non-equilibrium systems with complex multilevel space-time self-organization. The critical concentrations reflecting the transition from one state into another have been also established.

  • Origin of life: From chaos to orderliness
    • Authors: V. V. Goncharuk; O. V. Zuy; M. V. Milyukin
      Pages: 368 - 372
      Abstract: Investigated are physical and chemical conditions resulting in the formation of the ever complex organic substances from inorganic components. We investigated a number of chemical reactions running in underwater hot volcanic sources whose result is that from inorganic compounds form various organic molecules. Catalysts of the reactions may be solid particles containing transit metals that are present in hydrothermal waters. Products of reactions of reducing carbon dioxide under these conditions are formic, acetic, pyruvic acids and also methanol. This explains the formation also of more complex organic substances playing an important role in the origin of life in the medium of hydrothermal sources.

      Pages: 257 - 262
      Abstract: The paper has investigated structural mechanical properties of hydrogels from Na-carboxylmethyl cellulse and bentonite by the rheological method and showed that they depend on their composition. Hydrogels accumulate about 95% of water. Treatment of the surface of hydrogel by hydrophilic or hydrophobic aerosil slows down water loss in drying and destruction in the water medium.

  • Treatment of olive-pomace oil refinery wastewater using combined
           coagulation-electroflotation process
    • Authors: K. Hmidi; I. Ksentini; L. B. Mansour
      Pages: 275 - 280
      Abstract: Electroflotation is an aeration process which can be used to treat effectively industrial effluents. In the present work, a combined version of the electroflotation process with the coagulation operation was conceived to treat the olive pomace oil refinery wastewater. Batch and continuous mode of treatment was done in order to optimize the main operating parameters affecting the suspended solids elimination. In batch mode, the methodology of experimental research was adopted with these operating parameters: current density, pH and coagulant concentration. Then, the continuous mode aimed to optimize the residence time. As a main finding, the suspended solid removal efficiency and chemical oxygen demand abatement efficiency exceeded 92%.

  • NiFe 2 O 4 magnetic nanoparticles as an adsorbent for cadmium removal from
           aqueous solution
    • Authors: F. Moeinpour; S. Kamyab; M. R. Akhgar
      Pages: 281 - 288
      Abstract: The magnetic NiFe2O4 nanoparticles have been synthesized and used as adsorbents for cadmium removal from aqueous solution. The NiFe2O4 nanoparticles were characterized by scanning electron microscope (SEM), Transmission electron microscope (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectra (FTIR). Various parameters, which can affect the adsorption such as pH, adsorption time and adsorbent dose have been fully investigated. The results reveal that the magnetic adsorbent can be easily removed by a simple external magnet with high separation efficiency. In addition, the process is clean and safe for purifying water pollution. The prepared NiFe2O4 magnetic nanoparticles could thus be used as favorable adsorbents for the remove cadmium from polluted water.

      Abstract: Experimentally it has been proved the expediency of using biosorption and aeration for purification of wastewaters polluted with oil products. Using method of biotesting it was established that applying biosorption technology of purifying wastewaters polluted with oil products, one cannot observe an ecological risk for hydroecosystems. Investigated dynamics of the change of toxicity of the said water at their purification.

  • Modified anthracites for deironing of underground water
    • Authors: V. I. Romanovskii; A. A. Khort
      Pages: 299 - 304
      Abstract: The study deals with the investigation of anthracites that are widely used as a catalytic medium of deironing filters. Anthracite granules were coated with iron oxide by solution combustion synthesis (SCS) method in a microwave oven. The elemental composition of the surface of produced materials and the results of comparative analysis of the latter with initial anthracites used for the underground water deironing were presented. The control of the deironing efficiency was carried out in terms of the content of Fetot, Fe(II), and Fe(III). Regression equations describing the relationships of the Fetot and Fe(II) concentrations in filtrate as a function of the filtering duration and iron concentration on the surface of the modified anthracite were derived on the obtained data.

  • Optimal recultivation conditions of Candida Albicans staying in
           non-culturable state
    • Authors: E. S. Bolgova; M. N. Saprykina; V. V. Goncharuk
      Pages: 305 - 309
      Abstract: Optimal conditions for recultivation of Candida albicans staying in viable but non-culturable state have been established. The effect of sodium hypochlorite on the transition of this culture into non-culturable state was investigated. The conditions of the culture reactivation were determined. These conditions include the effect of M-9 nutrient medium components and the cultivation temperature on recultivation process.

  • Evaluation of eighteen west african plants for water purification,
           potential use for rural water treatment
    • Authors: W. B. Kpan; M. W. Koné; B. Bonfoh; K. Kamanzi
      Pages: 310 - 316
      Abstract: The current study evaluated the effectiveness of 18 West African plants for water purification. Water samples from 18 sites were collected in six villages in the Guiglo and Mankono regions of Côte d’Ivoire and analyzed for their potability according to WHO standards. Turbid water samples were treated by coagulation flocculation and sedimentation, with 18 plant extracts as coagulants, at concentrations of 200 mg·L–1. Moringa oleifera and chlorination were used as controls. Of the 18 water samples analyzed, three from hydraulic pumps were safe for drinking. For the 15 remaining samples (100–150 NTU), turbidity was reduced by 92% using Panda oleosa, Euadenia trifoliolata, Raphia hookeri, Napoleonaea vogelii, Piper guineense and Uapaca heudelotii. These plant-based coagulants showed similar performances as controls. R. hookeri and E. trifoliolata had reduction effects on iron and color of high colored water. These plants contained proteins, polysaccharides and tannins. Our findings show that plant-based coagulants, used in West Africa, may be applied to treat contaminated surface water to improve their quality for safe human drinking.
