An effective method of introducing nitrogen atoms to the surface MLCNT by treatment with a solution of urea, followed by heating. A series of studies on the qualitative composition and quantitative evaluation of oxygen-and nitrogen-containing functional groups on the surface of the original and modifiedMLCNT were done. By using the impedance technique, we examined the system, including organosilicas with different content of aminopropyl radicals and the solution of 1,1-electrolyte charge, that may influence the protonation of surface functional groups. The conditions under which the conductivity is proportional to the concentration of immobilized organosilicas aminopropyl groups, and conductive properties of organosilicas due to excess concentration of counterions in the diffuse component of the pore electric double layer and the electrolyte content in the external solution. The possibility of an impedance method for rapid diagnosis of organosilicas. According to the results of research in Ukraine received a patent "Method for determining the chemical composition and concentration of functional groups of organic sorbents by impedance method." Methods of the synthesis of functionalized silica microspheres containing a surface layer of the primary, secondary amino groups and etilendiamine are developed. The kinetics and statics of adsorption of nickel ions (II) and copper (II) sorbents are studied. Product Description popup.authors Бєлякова Л.О. Бакалінська О.М. Глевацька К.В. Журавський С.В.
