Figure 4.

Cyclic voltammograms of 1.0 mM ACT in the absence (dotted line) and presence of 9 mM solketal at different scan rates (25–120 mV s⁻¹) (a), and cyclic voltammograms of 1.0 mM ACT in the presence of various concentrations of solketal (b). Scan rate for dotted trace is 80 mV s⁻¹ and for traces in (b) is 25 mV s⁻¹. Solution conditions: aqueous solution with NaHCO₃/Na₂CO₃ electrolyte 0.1/0.1 M, and pH 10.
