Investigation of diffusion of ferrocene and ferricenium in aqueous and organic medium using voltammetry techniques

摘要

ABSTRACT The electrochemical behavior and diffusion of ferrocene and ferricenium in aqueous and organic medium was investigated by voltammetry on a platinum electrode. Both the ferrocene molecules and the ferricenium cations still show redox activity in both aqueous solution containing sulfuric acid and in dichloromethane solution containing tetrabutylammonium tetrafluoroborate. The results indicated that redox reactions of ferrocene/ ferricenium couple were a reversible process of diffusion-co.
