Aim of research is the development of theoretical principles and technologies of chemical surface modification of fine particles of condensation aerosols formed during heat treatment of metals. For the first time on the basis of a comprehensive study of qualitative and quantitative composition, dispersion and structure of active surface groups of samples of condensing aerosols developed by the scientific basis for creation of hydrophobic sorbents and theoretically justified the possibility of chemical modification of silicon surfaces with organic modifiers. Has refined the conditions for preparing and modifying the conditions of liquid-phase samples, the temperature regimes of preparation, modification and drying, the concentration of modifiers, the duration of the process of modification. Has refined the conditions for preparing and modifying the conditions of the liquid-phase samples of condensed aerosols, temperature regimes of preparation, modification and drying, the concentration of modifiers, the duration of the process of modification. Evidence-based selection of nature modifier, which yields a hydrophobic surface. The investigation of changes of surface chemistry in the process of modifying of dimetildihlorsilan, geksametildisilazan and trimetildihlorsilan. Determined the efficiency obtained in vitro modified samples in relation to the collection of oil from the water surface. Experimental studies carried out with the assistance of modern methods of chemical and physico-chemical analysis such as: thermogravimetry, atomic absorption, atomic emission spectrometry and spectrophotometry, electron microscopy, infrared spectrometry, diffuse reflectance spectra and adsorption methods for studies to determine the elemental composition and physico-chemical properties, the nature of surface active groups, particle size and disperse composition, to reflect modified surface structure in the process of modification. For the first time to deal with almost no processing of recyclable waste today finely divided metallurgical and welding engineering proposed a mechanism of directed chemical modification of their surface, which opens up broad prospects for developing their technology-based competitive in the sorbents for various applications.
