The objects are electrochemical and analytical properties of Ru(IV), Ir(IV), Rh(III), Pt(IV), Pd(II), Os(IV). The aim - determine of nature of reduction current of ions platinum's metals on mercury dropping electrode, electrochemical investigation of complex-forming process of Ruthenium with threephenylmethane dyes, with aim increase sensitivity of determination and elaboration selective methods determination Ru in the presence of platinum's metals. Methods of investigation: spectrophotometry and oscillopolarography. Results and newness: The complex-investigation of voltammetric behavior of ions platinum's metals in water solutions by hydrogen catalytic waves has been carried out. The electrochemical properties of pyrocatechol violet and eriochrome cyanine R were found. The methods of Ruthenium determination in complex compositions with Cmin ~ 1-2 ? 10-7 mol/L with co-existence of platinum metals in the presence of threephenylmethane dyes has been elaborated. Determination of Ruthenium in semiconductive pastes and alloys has been carried out. The field is analytical chemistry
