Figure 5: Cyclic voltammograms of  M MG in 0.10 M aqueous solution of KCl at various concentrations of surfactants. (a) Cyclic voltammograms of MG in the presence of CTAB. Concentrations of CTAB (from I to VI): 0, , , , ,  M. (b) Cyclic voltammograms of MG in the presence of SDS. Concentrations of SDS (from I to VI): 0, , , , ,  M. The scan rate was 0.01 V s−1. Insets show plot of versus [surfactant].
