Vakulich A. The reaction of diferent ligand iso- and heteropolycomplexes with threephenilmethan's dyes and anionic surface-active sabstances

The reaction of the formation of the associates of P (V) and Ga (III) molybdotungsten heteropolyanions with organic dyes in anionic SAS presence were stadied. In the work the different reseach methods were applied: spectrophotometry, UV, visible, IR-spectroscopy, amperometric titration. Composition and stability constants of associates are determinated and the regularity of changing stability of them from the heteropolyanions charge and electronic parameters of organic dyes was found. The sensitive, simple spectrophotometric methodes of determinating of these elements are woked out. The reaction of the formation associates of isopolyanion - organic dye are staded at fist. It was used for determination of the tungsten in molubdenum matrix. Method of determination of the phosphorus in sewage are apply in laboratory of "Nighnedniprovsk tube-rolling mill" c.Dnipropetrovsk.
