Leonova N. Spectrophotometric analysis of mixtures of some d-elements when signal components was imposition using two intense parameters

The dissertation is devoted to study and optimize the conditions for spectrophotometric determination of ions with 1-(2-pirydylazo)-2-naphthol (PAN) in water-micellar environment depending on two parameters intensive wavelength and pH individually and in joint presence. The algorithm of mathematical processing of results of determination by the method of ion inscribed surface. And comparing the obtained values with the data calculated by the classical method of least squares, method of principal component and partial least squares. Investigated and optimized procedures methodology for determining components of metal ions with PAN in aqueous micellar medium. Exchange reaction studied PAN 8- hydroxyquinoline complexes in ion Ni2+, Co2+, Fe2+, Cu2+, VO2+ in water and micellar environment. The optimum concentration of surfactant anionic type. Logarithm constant exchange Cu2+ is 3.87. The conditions that ensure the determination of solubility constants of complex compounds with organic ligand in water.
