Abstract

The electrochemical polymerization of brilliant cresyl blue (BCB) has been carried out using cyclic voltammetry in the potential region between −0.20 V and 1.15 V (vs. Ag/AgCl with saturated KCl solution). The electrolytic solution consisted of BCB (0.1 mol/L) and Na~2~HPO~4~(0.2 mol/L) with pH 2.1. BCB can not be polymerized at pH < 1. There are an anodic peak and a cathodic peak on the cyclic voltammogram of poly (BCB) at pH ≤ 4.3. Both peak potentials shift towards more negative with increasing pH value, and their peak currents decrease with increasing pH value. Poly (BCB) depicts a good electrochemical reversibility, fast charge transfer ability and stability in aqueous solutions with pH ≤ 4.3. The visible spectrum, FTIR spectrum and Raman spectrum of poly (BCB) are different from those of BCB.
