Gontar O. The new extraction systems for platinum metals, zinc and molybdenum selective concentration and determination in ecological safety conditions

The Objects of the research: different-charged Ru(III), Rh(III), Zn(II), Mo(V) chloride and thiocyanate complexes, Pt(II) complex with SnCl2, different-radical organic basis, water-soluble extractants. Purpose: the development of the new ecological safe approaches for concentration, separation and determination of platinum and others metals in multicomponent objects. Methods: spectrofotometry in UV, seen and IR area of the spectrum, atomic absorption spectroscopy, gas chromatography, NMR1H - spectroscopy, titrimetry, atomic emission spectroscopy with inductive coupled plasma. Studied: the regularities of structure and properties of primary, different-radical tertiary alkylamynes influence on their ability to extract the Rh(III), Ru(III), Pd(II) highly-charged complexes from concentrated chloride solution. The external sphere extraction mechanism and extracting associate composition were found out. Ecologically safe extraction systems for extraction thiocyanate complexes of Pd(II), Ru(III), Mo(V), Zn(II), complex Pt(II) with SnCl2 were proposed. The associates composition and constants of extraction were determined, hydro-solvate mechanism was established. The application pegree: the received results were used for the development of rapid, selective methods for separation, concentration and determination of platinum and other metals in scrap and radioelectronic equipment waste, technological solutions, alloys, waters.
