Thin-Layer Cyclic Voltammetry Using Orthogonal Collocation

Thin-Layer Cyclic Voltammetry Using Orthogonal Collocation 

The couple is confined within a layer of thickness d. The following diffusion equations must be solved for each half of the couple  

The reaction is assumed to be rapid, and as such concentrations of the species at the electrode surface follow the Nemst equation  

At the electrode surface the amount of O consumed and the amount of R produced are related, so their concentration slopes at the electrode surface are equal in magnitude and opposite in sign  

Furthermore both species are confined within the thin layer, which means
