Karazin popup.description2 The substances studied - metals (copper, aluminium, tin, germanium, niobium, potassium) and alloys, aqueous and aqueous-organic solutions, dyes, amino acids. The aim of the work is the investigation of chemical composition influence on the metal ionization and electrocrystallization, determination of the most important spectral, thermodynamic and structural properties of the associates, containing benzenepyril- and xanthene-dyes, as well as of aqueous-organic solvent effect on standard thermodynamic functions of amino acid solvation and dissociation. The results of the study of the composition of salines, containing chloride ions and inhibiting components, on corrosive and anode behaviour of the aluminium with the goal of optimal electrolyte composition choice for use in the storage batteries have been given. The processes of chemical and electrochemical copper and it zinc alloys (L-62, L-68) dissolving in solutions of various composition have been studied.The influence of solvent nature, cathode material, acidity of xylol solutions and degree of preliminary current processing on kinetic parameters of stage cathode processes (transport current and carrying coefficient), Al(III)-containing complexes discharge polarization, limiting currents, aluminium current yield has been studied. The most important spectral, thermodynamic and structural properties of the associates, containing benzenepyril and xanthene dyes have been determined. The possibilities of heteroassociates interaction with ionic surfactants and complex metal ions (on example of complex cyanide iron ions) have been studied. The interpretation of aqueous-organic solvent influence on standard thermodynamic solvation and dissociation functions of amіno acids has been done. The quantitative chemical models of interparticle interaction have been applied for the theoretical description of amino acid thermodynamic properties concentration dependence. Specific interactions of anions and cations with biophysically meaningful amino acids have been studied at high electrolyte concentrations. The results of solvation-thermodynamical analysis of aqueous-organic solvent (water-methanol, water-propan-2-ol) influence on acetic and benzoic acids and silver monocarboxylate complexes stability at standard state have been given.
