Abstract
The main problem with kinetic measurements in cyclic voltammetry is connected with the increase or the ohmic drop IR S , where R S is the uncompensated solution resistance, as the sweep rate increases. Although modern potentiostats allow some compensation or R S , total compensation is not possible. The presence or the uncompensated resistance causes nonlinearity or the potential sweep and leads to an increase in the separation or peak potentials, which may result in erroneous kinetic parameters. The development or ultramicroelectrodes has increased the possibilities or cyclic voltammetry at high sweep rates
