DC. The current rises with increasing voltages up to a limiting value.
Please click here to download the parameter file, open the parameter file in software Electrochemist. Click the Plot menu, the Y Data submneu, and the -Y submenu. Because in classic plot of voltammetry, oxidation current is defined as negative current, so you need to plot the -Y DATA.

As above, but click the Plot menu, Option menu, untick the "x axie from + to -" to change the x-axie direction.

CV, scan rate = 1 kv/s, fit a simulated curve to experimental CV.

As above, scan rate = 1 kv/s, separate the overlapped peaks of CV.

CV, scan rate = 5 kv/s,

CV, scan rate 5 kv/s,

CV

Separate overlapped peaks of LV.

Separate overlapped peaks of LV.

A cyclic voltammetric simulation that can be applied to an electrochemically mediated enzyme reaction involving any substrate and mediator concentrations was fitted to experiement.
electrochemical reaction: O+e=R
enzyme reaction: O+S = R+P
where R, O, S, and P are the reduced and oxidized forms of the mediator, substrate, and product, respectively.
scan rate is 10 mV/s, Uncompensated solution resistance is 3.4 ohm, cylinder electrode: radius is 4e-2 cm, length is 60 cm (so electrode area show 1.5 square centimeters),
Determination of electrochemica Kinetic Constants: E0= -0.17 v, ks= 2e-3, alpha =0.5
Determination of Enzyme Kinetic Constants: kf=18, kb=20.
