Abstract
The numerical integration of the differential equation for cyclic voltammetry has been performed for the case where the reverse potential is set prior to the forward peak potential. A working curve stemming from these integrations allows the determination of the half-wave potential of species limiting the potential window. This technique has been applied to the measurement of formal Gibbs energies of transfer of ions across the water/1,2-dichloroethane interface. The validity of the TATB (tetraphenylarsonium tetraphenylborate) assumption is also discussed.Keywords
