Abstract—The theory of linear-sweep voltammetry (LSV) applied to heterogeneous redox reactions accom-
panied by the nondissociative adsorption of the reactant or the product is developed. The basic criterial relation-
ships of LSV in this case are invariant with respect to the type of adsorption isotherm and the number of adsorp-
tion sites occupied by one species. The degree of irreversibility of the discharge–ionization step can be evalu-
ated from the effect of the potential scan rate on the peak potential. The nature of the adsorbate can be deduced
from the effect of the reactant concentrations on the peak current.
Key words: linear-sweep voltammetry, heterogeneous redox reaction
