Özet:

 

This paper presents the results of an investigation of   the properties of a modified platinum electrode with   meso-tetraphenylporphyrin iron(III) complex immobilized in Nafion film and its   catalytic activity in the electrochemical oxidation of selected hydroquinone   and catechol derivatives. The redox activity of iron complexes of porphyrins   was characterized in aqueous solutions of perchloric acid by means of cyclic   voltammetry and differential pulse voltammetry. Both the increase in the   anodic peak currents of the investigated compounds during oxidation on the   platinum electrode modified with meso-tetraphenylporphyrin iron(III) complex   immobilized in Nafion film (FeTPhP/Nafion/Pt) and the considerable decrease   in the cathodic peak currents related to the porphyrine complexes reduction   point to mediatory activity. The increase in the oxidation currents observed   during the preparative electrolyses indicates that the modified platinum   electrode, FeTPhP/Nafion/Pt, exhibits catalytic properties. The preparative   electrooxidation of the investigated 1,2- and 1,4-hydroquinone derivatives   showed that over 90% conversion of the substrate occurs in the shortest   time on platinum modified with iron complex of porphyrin immobilized in   Nafion film.
