The structure and chemical composition of the surface of nanoporous organic-inorganic materials were characterized by means of elemental and chemical analysis, UV and IR spectroscopy and sorption measurements. Active centers of adsorption of cationic forms of lead have been identified and the relation between sorption affinity of the surface beta-cyclodextrin-containing organosilicas and chemical nature of the side edge of the broad functional groups grafted molecules of beta- cyclodextrin. Forecast assumptions for the development of object of study - derived beta- cyclodextrin-containing siliceous materials can be used for rapid analysis of trace amounts of lead (II) in drinking and wastewater. Methods of surface functionalization of nanoscale carbon material , such as single- and multilayer graphene by liquid-phase oxidation of surface acid azotnoy solutions were worked out. An effective method of introducing nitrogen atoms to the surface of OGr by treatment with a solution of urea , followed by heating was developed. Series of studies was conducted to study the qualitative and quantitative evaluation of nitrogen and oxygen - functional groups on the surface of initial and modified graphene. Using two- and three-component (for alkoxysilanes ) systems methods for the synthesis of silica microspheres with mono- and bifunctional amino surface layer was developed, their composition and morphology were studied. It was shown the possibility of sorption for such samples as metal ions ( copper ( II) ), and biomolecules. Product Description popup.authors Бєлякова Л.О. Бакалінська О.М. Войтко К.В. Зуб Ю.Л.
