Electrochemical Characteristic of Alizarin Red S Existing in Polypyrrole Film as a Dopant

Abstract

Abstract: The cyclic voltammetry was employed to study the influence of the polymerization potential and charge on the property of the polypyrrole(PPy) film electrode containing Alizarin Red S(ARS), and of the scan potential range on the redox behavior of ARS. It has been demonstrated that the interaction of ARS molecules with PPy chains exists in the redox process of ARS between -0.60 V and 0.40 V. Based on the experimental finding, a possible reaction mechanism was suggested.

Key words: Cyclic voltammetry, Alizarin red S, Polypyrrole, Modified electrode
