Sažetak
A model of electrode reaction complicated by slow adsorption of the reactant is developed for square-wave voltammetry with inverse scan direction. The relationship between dimensionless net peak current and the logarithm of dimensionless rate constant of adsorption is a curve with the minimum and the maximum. For this reason the ratio of real net peak current and the square-root of frequency is a non-linear function of the logarithm of frequency and exhibits either maximum, or minimum. The frequency of extreme serves for the estimation of the rate constant: log(kads/D1/2) = log( )crit + 0.5 log fcrit, where ( )crit is a critical dimensionless rate constant of adsorption. Square-wave voltammetry is sensitive to the kinetics of adsorption if kads < 102 cm/s.
