ABOUT COMPARATIVE POLARITY OF As=N AND P=N GROUPS

abstract 0781204019 issue 78 pp. 222 – 233 30.04.2012 ru 1823
By the method of the dipole moments the connections of (p-XC6H4)3As=N-C6H4-Y series have been examined. The method of the vector-statistical analysis of the dipole moments helped to define the ranges and directions of the moments of (Сар)3As=N-Cар, (Сар)3As=N и N-Cар series. There has been shown that the substitution of the para-assistants X and Y in aromatic groups doesn't lead to an additional interaction influencing the electronic properties of the (Сар)3As=N-Cар group. The comparative analysis of the (Сар)3Э=N-Cар (Э=P, As) group moments specifies the essencial shift of the electron density to Сар(N) when replacing atom P to As

ABOUT POLARIZATIONS EFFECTS IN THE RANKS OF ЭХ3 MOLECULES

abstract 0991405018 issue 99 pp. 256 – 265 30.05.2014 ru 1958
Correlations between experimental dipoles moments and values of the difference of first potentials ionization of atoms and molecules (ΔE) for three -coordinated molecules of types ЭХ3 (Э=N, P, As, Sb are carried out; X=F, Cl, Br, I ) are described. Exponential functions of dependence μ= f(ΔE) for rows ЭF3 andЭCl3 are received. Within the valence of shell electron pair repulsion theory it is shown, that the molecular dipole moments can be divided to dipol moments of ions of separate atoms, which, naturally changing, are transferred in the ranks of molecules ЭХ3

NI, CR, PB IN HYDROMORPHIC SOILS OF THE TEREK-SULAKSKOY SUBPROVINCE OF DAGESTAN

abstract 0761202017 issue 76 pp. 196 – 205 29.02.2012 ru 2006
In the article, we investigated hydromorphic soils of the Tersko-Sulak subprovince of Dagestan. We determined the content of humus, nickel, chromium and lead with genetic horizons of the investigated soils. The small excess of the maximum allowable concentration of nickel and chromium has been found, doze of lead was within norm

BASIS OF SYNTHESIS OF MODIFIED SORBENTS AND SORPTION OF HEAVY METALS FROM WASTE WATER OF INDUSTRIAL ENTERPRISES

abstract 0921308059 issue 92 pp. 885 – 893 31.10.2013 ru 2041
In the article we have estimated sorption capacity of sorbents and analyzed the factors influencing it; we have also selected the optimal conditions for the sorption process, depending on the circumstances and nature of the treatment facilities. The possibility of purification of oil-contaminated water from heavy metal ions synthesized inorganic sorbent has been shown

INCREASING ENVIRONMENTAL SAFETY OF PRODUCT RECYCLING OIL SLUDGE

abstract 0781204064 issue 78 pp. 806 – 815 30.04.2012 ru 2055
In this article, the recycling problem of oil sludge on some modern refinery factories is observed. We studied physical and chemical structure of oil sludge and offered a new way of neutralization of oil sludge. It is established, that if we replace a carbon sorbent to sorbent that contains silica for oil sludge neutralization, we will get environmental safe product. As such sorbent, which contains silica we offer to use a burnt rice peeling. For practical realization the way of neutralization is developed and technological scheme which allows to save natural resources (hydrocarbons and water) and return it to production cycle and to recycle the petropolluted sludge is offered
