Domestic systems for air cleaning, moistureing freeng of dust and bac-terias // Tomsk State Pedagogical University Bulletin. 2000. Issue 2 (18). P. 54-63

The set of devices for treatment of air against and for various characteristics of its content are designed (purification, moisturing, ionization, filling with medicines, aromatizing fumes, etc). A historical outline of development of biological and technical findings in this field. This information was used for formulating unsolved problems in air purification field

Usage of polymeric fiberous sorbents purification of waters wasted by «sibcabel» plant // Tomsk State Pedagogical University Bulletin. 2000. Issue 9 (25). P. 62-63

It is established that under pressureless filtering throughthe fiberous polypropilen the purification process is the more effective the less is the initial concentration of pollution this material is prevailing other materials in its mechenical, chemical resistance and sorbtional capasity. The maximal degree of purification is acheived 85.7% for Cu, 88.5% for Fe, 68% for suspension, 86.3% for oil products, 46.3% for Zn, 71.4% for phosphates.

Water de-ironing on fiberous thermoplastic sorbents // Tomsk State Pedagogical University Bulletin. 2000. Issue 9 (25). P. 64-65

Technology of water de-ironing is presented, based on filtering water trough fiberous sorbents made by the formation fiberes of melted polypropilen, type 21030-6, spilled from rotating disc. In is established that degree of water de-ironing and the working ability of the filter greatly depend on filter staffing density and on thickness of iron hidroxide layer over the fiber. The ultimate concentration of iron in water after the filtering is less than 0,3 mg/1 under initial concentration about 10 mg/1, if the staffing density is 140 through 200 kg/ m cub. and height of filtering layer is 200 mm.

Technology and equipment for removing oil products from water by polymeric fiberous materials // Tomsk State Pedagogical University Bulletin. 2000. Issue 9 (25). P. 65-67

Main characteristics and sorbtional properties of polymeric fiberous materials made of thermoplastic wastages have been studied. It is established that the highest abilities of filtering oil-products is reached with proportions between a product and filter masses of: 6.0 through 9.31 for raw oil, 6.0 through 13.0 for oil type И-20, and 3.5 through 9.95 for diesel oil. They are dominating widely used filtering materials such as sul-focarbon and activated carbon. Regeneretion of fiber-ous sorbents is made by centrifugeing with separation factor equal to 100. Sorbtion capacity decreases no more than 20% after 50 regeneration cycles.

lonexchanging fiberous materials from thermoplastic wastages // Tomsk State Pedagogical University Bulletin. 2000. Issue 9 (25). P. 67-69

It is described how to produce polyolefines and pol-yethers from thermoplasts by sulphation of polystirol. The polystirol is introduced into the propilen in the pro¬portion of 5 through 15% in mass. The largest static exchange capacity belongs to the fiber obtaind by treating it with a sulfic acid of 93% concentration under temperature of 100-105 grad.C. The acheived purification coeffitient for Cz-137 is near to that acheived on ion-exchanging material of КУ-2-10 type.

The Analysis of a Level of Pollution by Priority Substances in Аbakan of Republic Khakasia // Tomsk State Pedagogical University Bulletin. 2006. Issue 6 (57). P. 83-86

The results of airpollution monitoring in towns of Republik of Khakasia demonstrate that the average annual concentration of benzapilene increased by 14,6 % in Abakan, 51% in Sayanogorsk and 24 % in Chernogorsk in 2002. 47,7 % of emissions fall to mototransport’s lot. The analysis of snow and soil by the method of gas chromatography and chromatography – mass spectrometry in the zones of blowout dispersion by the heat and power plant of «Khakasenergo» proved that the content of benzapilene in the blanket of snow is 4·10-5 mg /dm3, in the soil is 0,0010 mg /kg. The usage of different methods of atmospheric emission purification and technology of complete combustion of fuel contribute to the solution of enviromental problems. Per 2003–2004 years the analysis of a snow cover and ground on pollution BP in various areas of city Abakan is carried out in view of sources of pollution
