The Simulation of Differential Pulse Voltammetry

Electroanalysis, 2001
The differential pulse voltammetry (DPV) experiment has been simulated using the backwards implicit finite difference approach. Results are reported for the general case of a one-electron redox transfer process at a planar electrode in stationary solution with a semiinfinite diffusion layer and are in excellent agreement with those predicted by an ...
