INFLUENCE OF ORGANIC SOLVENTS ON WATER DISSOCIATION IN BIPOLAR MEMBRANE

abstract 1141510019 issue 114 pp. 261 – 274 30.12.2015 ru 1260
The article discusses results of experimental research of the influence of aprotic and proton solvents on reaction rate of water molecules dissociation in the bipolar membrane MB-1 by the method of electrochemical impedance frequency spectrum. It was discovered, that addition of organic component in aqueous solutions results in significant influence on the parameters of water dissociation in a bipolar region of the membrane. The reason for this influence is the reduction of the mass fraction of water in solution and, consequently, in a bipolar region of the membrane, which itself reduces the rate of the dissociation reaction. Another reason for the influence of the organic solvent is its effect on the network of hydrogen bonds existing in water and aqueous solutions. Depending on the nature of organic solvent and its concentration, the network of hydrogen bonds may be strengthened, or destroyed, thus facilitating removal of the proton involved in the reactions between water molecules and catalytic centers in cation-exchange and anion-exchange layer of bipolar membrane, or retarding removal of proton. This leads respectively to speed up or slow down the rate of dissociation in the bipolar region of the membrane, as well as changing the constants of the dissociation reaction of water. Introduction of organic solvent in solutions, which are in the contact with bipolar membrane, is a convenient method of investigating the role of solution composition on the rate of proton transfer between water molecules and catalytic centers in the membranes

BOUT REGULARITIES OF CHANGES OF VALENT ANGLES AND POTENTIALS OF IONIZATION IN THE RANKS OF ЭХ3 AND ЭХ2 MOLECULES

abstract 0951401056 issue 95 pp. 980 – 993 30.01.2014 ru 1345
Correlations between values of the differences of first potentials ionization of atoms and molecules (ΔE) and valency angels α for three coordinated molecules of types ЭХ3 (Э=N, P, As, Sb are carried out; X=F, Cl, Br, I, CH3), and also ЭХ2 (Э=O, S, Se, Te; X = CH3, SiH3, GeH3) are described in this article. It is shown, that the entered value ΔE can serve as additive measure of change of the valency angle α in the basic and raised stances. We have also established that the functional dependences correlate with changes in the of hybridization of orbitals and the R parameters characterizing the interaction of electronic pairs near the central Э atom

ELECTROCHEMICAL STABILITY OF STRONG BASIC ANION EXCHANGE MEMBRANES IN CONDITIONS OF HIGH INTENSIVE ELECTRODIALYSIS PROCESS

abstract 1041410045 issue 104 pp. 617 – 629 30.12.2014 ru 1362
The stability of strongly basic anion-exchange membranes MA-41-2P (JSC "Schekino-Nitrogen", Russia) and AMX (Tokuyama Soda, Japan) under intensive current regimes was investigated in the current study. The process of water molecules dissociation at current densities above the limiting one in 0.01 M sodium chloride solution was studied in detail. The length of the electroconvective instability at the membrane / solution interface at currents exceeding the limiting current was measured by laser interferometry

FEASIBILITY STUDY OF SORPTION CLEANING IN THE OIL CONTAMINATION LIQUIDATION

abstract 0841210067 issue 84 pp. 855 – 864 28.12.2012 ru 1434
In the article, we have investigated a number of characteristics of the sorption materials, the possibility of their use for the treatment of surface and waste water from oil and oil products. The rules of the cleaning oily water, the analytical solution for sorption purification process that takes into account the processes of filtration and sorption are listed. We have also estimated sorption capacity of sorbents and analyzed factors that influence it; the optimal conditions of the sorption process, depending on the conditions and the facilities for cleaning are sorted out. The possibility of purification of oil-contaminated water from heavy metal ions with the synthesized non-organic sorbent is shown
