Karazin popup.description2 The aim of the work - study of physicochemical regularities of metals ionization and electro crystallization in aqueous and non-aqueous solutions and conditions of formation of semi- and su-per- conductive layers with desired properties elaboration, investigation of associate formation in aqueous solutions, investigation of inter particle interactions and calculation of dissociation ther-modynamic functions in amino acids, their salts and derivatives solutions. Methods: dynamic voltamperometry, potentiometry, chronopotentiometry, gravimetry, spectro-photometry, X-rays, vapor pressure osmometry.The formation of equpotential pairs have been established is possible in acetonitrile media. These pairs are characterized by quick electron transfer according with bridge mechanism. The influence of different nature electrolytes composition on corrosive and anodic alumin-ium behavior is studied; the process of ingibition of metal corrosion in aqueous-organic electro-lytes is considered. Electrolytes composition influence on kinetic parameters of charge and electro precipitation of germanium and niobium from non-aqueous media on different metals to formate the semi and super conductive layers is studied. The kinetics of cathodic processes on niobium in alcohols and the features of cathodic processes kinetics in xylene and xylene electrolytes of aluminiation is ex-aminated. The complex formation of copper in nitrate contained system is investigated. Modificatory influence of impurities investigated has been shown is stipulated by their ability to bind the copper ions in stable complexes with cyclic groups formation. The research of mixed cationic-anionic association process in aqueous solutions is provided, the influence of surfactants and organic component additions on associate formation with participa-tion of rodamines and oxyxanthenes is established. The osmotic coefficients and activity coefficients of glycine, histidine, glutamic acid, their salts and derivatives in aqueous solutions are obtained. Theoretical modeling of amino acids and their salts is provided. The a-alanine and valine dissociation constants in methanol-water, propan-2-ol-water system are measured at 278.15-328.15 К. The standard Gibbs energy of transfer of ionic forms of a-amino acids in MeOH-H2O, PrOH-2-H2O mixtures has been calculated. The regression correlative analysis of the aqueous-organic solvents (water-methanol, water-ethanol, water-propan-2-ol) effect on the strength of amino acids (a-alanine, valine) has been provided at 298.15 K.
