Comportement electrochimique de ferrocene,du perylene et du tetracene dans une electrode a pate de carbone a liant electrolytique dans les melanges eau-acide phosphorique

摘要

The carbon dough electrode with incorporated electrolyte has been used to analyse the electro-chemical behaviour of ferrocene,tetracene and perylene in phosphoric acid media 0.1 to 14.8M.The cyclic voltammetry results obtained for ferrocene withthe carbon dough electrode corroborate with polarographic data.Voltammetry study of the aromatic hydrocarbon oxidation Ar such that of perylene and tetracene on the carbon dough electrode has allowed to establish the normal potential of the corresponding oxido-reducing systems.The existence of the four oxidation states:Ar,Ar~+,ArH~+ and Ar~(2+) at different concentrations of phosphoric acid is specified.The results of this study cn be used to establish correlations between some of concentrated solution properties of different acids.
