Cupric hexacyanoferrate colloid doped polypyrrole film modified electrode

Abstract

Abstract Anionic colloid cupric hexacyanoferrate (CuHCF) was incorporated into polypyrrole (PPy) films in the course of electrochemical polymerization of pyrrole from aqueous solution containing pyrrole and CuHCF colloid. The films obtained were dark brown in color. Three redox peaks appeared in the cyclic voltammogram (CV). The peaks around 0.7 V (vs, SCE) showed cation‐selective properties. X‐ray photoelectron spectroscopic analysis and ultraviolet‐visible (UV‐vis) spectroscopic properties of the film were investigated.
