FEASIBILITY STUDY OF SORPTION CLEANING IN THE OIL CONTAMINATION LIQUIDATION

abstract 0841210067 issue 84 pp. 855 – 864 28.12.2012 ru 1485
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

MODELING OF CULTIVATION ON PRODUCTIVITY LACTIC ACID PRODUCER LACTOCOCCUS LACTIS CH5

abstract 0831209044 issue 83 pp. 634 – 642 30.11.2012 ru 1933
The equations for evaluation of the stationary state of lactic acid microbiological synthesis have been received. The kinetic dependencies for specific biomass growth rate, consumption of the substrate are given. The particular qualities of growth of homofermentative lactic acid producer Lactococcus lactis CH5 depending on the composition nutrient medium: glucose and yeast autolysate concentration are examined. The influence of the method of cultivation on the productivity and the speed of the lactis acid synthesis are analyzed

THE DIPOLE MOMENTS AND THE STRUCTURE OF THE FOUR-MEMBERED CLOSED-CHAIN ARSENIC COMPOUNDS

abstract 0781204020 issue 78 pp. 234 – 243 30.04.2012 ru 1178
By the method of dipole moments, there has been determined that the tri-coordinated arsenic derivatives (p-XC6H4AsN-R)2 with R= Bu-t in the liquor exist in a cis-form, as for R=С6Н4Х-p the trans-structure is being realized. As for tetra-coordinated derivatives [XC6H4As(S)NBu-t]2 the trans-form is also beeing observed. For ortho-substituted connections, the angles of flat surfaces rotation of benzene rings have been defined

INCREASING ENVIRONMENTAL SAFETY OF PRODUCT RECYCLING OIL SLUDGE

abstract 0781204064 issue 78 pp. 806 – 815 30.04.2012 ru 1793
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

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

abstract 0781204019 issue 78 pp. 222 – 233 30.04.2012 ru 1542
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

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

abstract 0761202017 issue 76 pp. 196 – 205 29.02.2012 ru 1653
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
