ولتامتری جذب- دفع – کامسول

For an electrochemical reaction to occur, the reacting species usually needs to adsorb to the electrode surface before undergoing reduction or oxidation, after which the resulting product species desorbs back into the electrolyte.

If the rate of adsorption or desorption is slow in comparison to the electrochemical charge transfer step, the adsorption-desorption phenomena may have to be accounted for in a model.

This example investigates the impact of various kinetic parameters for adsorption, desorption and electron transfer when performing cyclic voltammetry on a planar electrode.
