Abstract

The electrochemical studies of the dye molecule, Neutral Red (NR) as!'iurne importance in view of its redox characteristics. The oxidised and reduced forms of NR, depending UpOIl the solution pH, undergo different protonation reactions. The electrochemical behaviour of NR (3-arnino-7-dimethylarnino-2-methyl phenazine) has been studied voltarnrnetrically on a glassy carbon electrode at different pR conditions. The investigations indicate that the electroreduction of NR follows a single stage 2e-transfer. Based on the voltammetric data, the diffusion coefficient of NR and the heterogeneous rate constant for its reduction reaction have heen estimated. The results or the above investigations are presented and discussed in this communication which also includes absorption spectral data or NR in the visible image.
