Figure 1. Voltammetry of 2,6-dimethoxy benzoquinone.

Figure 1

a) Cyclic voltammograms of 50 μM BQ recorded in 0.1 M buffer solutions having different pH at v = 30 mV/s. KCl-HCl solutions have been used in regions of strongly acidic pH, acetate buffers in moderately acidic pH regions and phosphate buffers in neutral and moderately alkaline pH. For pH > 10 NaOH solutions were used as electrolytes. b) pH dependence of the mid-peak potentials of CVs from a. c) Time evolution of CVs of 100 μM BQ dissolved in 0.1 M NaOH.
