Abstract >>
Anion-active surfactants on the ground of sulpho derivatives of a mixture of fatty acids isolated from corn oil and individual linolenic acid were obtained. Physicochemical properties of surfactants and calcium salts synthesized on their ground have been defined. Research with thin (0.160.17 mm) films of petroleum on the surface of various waters (fresh, distilled, sea) has shown that these salts as 5 and 10 % solutions of ethanol possess good petroleum collecting and petroleum dispersing properties. It has been established that 0.025 and 0.05 % solutions of calcium salts are biodegradable.

Pages: 161171

Abstract >>
A method for the synthesis of the application material for medical purposes based on the carbon hemosorbent is described. The chemical modification of a carbon material was performed via impregnation by azobisisobutyric acid dinitrile (DINIZ) in monomer N-vinylpyrrolidone (VP) with the subsequent polymerization. Selecting the optimal parameters of the modification that allow applying up to 815 mass % of poly-N-vinylpyrrolidone (PVP) onto the carbon sorbent is described in detail. As the general analysis we used a thermal method that provides monitoring the VP polymerization process on the carbon material. The proposed method for the synthesis of PVP on the surface of the carbon sorbent was compared with alternative methods of PVP preparation on the surface of different nature carriers. The analysis of the physicochemical properties of the studied sorbents is presented. The reported results of microbiological studies have demonstrated the possibility of using carbon sorbents for the vulnerosorption.

Abstract >>
Concentrations of K, Ca, Mn, Fe, Zn, Sr, Cu, Br, Rb, Pb in fruits of dog rose (Rosa canina) collected in areas with various technogenic load: Novosibirsk, Istaravshan City (Tajikistan), Gorny Altai have been determined by the method of X-ray fluorescence analysis using the synchrotron radiation (SRXRF). The highest concentrations of essential elements (K, Ca, Mn, Fe, Cu, Zn) have been discovered for samples from Istaravshan City. It has been found that in pulp of plant fruits growing near the highway (Novosibirsk) concentrations of essential elements of K, Mn, Fe are several times lower, in comparison with data for the territory not experiencing the technogenic load (the forest area of Novosibirsk) and the concentration of Pb in them does not exceed the maximum permissible concentration (MPC).

Pages: 185192

Abstract >>
A synthesis of carbon nanomaterials was performed via decomposing hydrocarbon feedstock having various compositions (natural gas, propanebutane mixture) at 700 using a 20 % Ni/SBA-15 nickel catalyst. As the carrier for nickel catalysts we used mesoporous silicate material SBA-15 with a fixed pore diameter. It has been demonstrated that the preliminary functionalization of the carrier with amino groups provides a high dispersity of nickel particles due to their stabilization within the channels of the mesoporous silicate matrix. The maximal yield of carbon nanomaterials (27 g/gNi) was achieved in case of using a mixture of C3C4. The product is presented by hollow carbon nanofibers with a diameter of 1050 nm. The HRTEM method demonstrated that the formation of carbon filaments occurred owing to active centers attached to the outer surface of the carrier. The metal particles located within the pores of the SBA-15 matrix do not participate in the process. An effect of carbon methanation exerted on the yield of a carbon nanomaterial and its morphological features has been studied.

Abstract >>
The dynamics of processes of mineralization of basic types of organic wastes of biotechnical systems of bioengineering systems of the life support in the medium containing hydrogen peroxide, under the action of the alternating electric current was described. Time and electroenergy were evaluated, as well as the degree of mineralization of wastes at the regime of oxidation corresponding to the maximally effective transition of mineral elements into the form, available to plants. The reverse dependence between the intensity of the mineralization process and such parameters, as the degree of waste mineralization, effectiveness of H2O2 and energy use was established.
