Question

How to integrate cyclic voltammetry curve in origin?

Answer 1

Explanation:

Use it as it is. Its unit is Coulomb. When we say the integrated area is the same with charge, it is in magnitude but the unit is Coulomb.

Then this unit will be canceled out by the unit of Faraday, when we calculate surface concentration of the electroactive species (C) using the formula

C = Q/nFA

Q = is the charge consumed in coulomb obtained by integrating the peak area.

A = is electrochemical active electrode surface area in cm2

F = is Faraday constant (9,6485 C mol−1) and

n = number of electrons participated in the electrode reaction
