Electrochemical Study of Esculetin Nitration by Digital Simulation of Cyclic Voltammograms

Figure 2

Cyclic voltammograms of 1.0 mM esculetin in the presence of 5.0 mM nitrite ion, at a glassy carbon electrode, in phosphate buffer solution (pH=6.0, 𝑐=0.15 M). Scan rates from (a) to (d) are 10, 20, 40, and 80 mVs⁻¹, respectively. Inset: variation of cathodic-to anodic-peak current ratios versus scan rate.
