A contribution to the theory of pulse polarography I. Theory of current-potential curves.
TL;DR: In this article, a general theory of pulse polarographic current-potential curves is developed for a simple electrode reaction proceeding at the expanding plane electrode, where the ratio of the sampling time to the pre-electrolysis time is smaller than 1/30.

Voltammetric titrations involving metal complexes: Effect of kinetics and diffusion coefficients.
TL;DR: In this article, a theoretical analysis of the voltammetric titration of ligand with metal, under the condition that the diffusion coefficients of the complex and the free metal are unequal, is presented.

Differential normal pulse voltammetry-theory
TL;DR: In this paper, a modified form of differential pulse voltammetry, in which two potential steps with similar short duration are superimposed on the rest potential, is presented, and expressions for the current response to the double potential step are derived for quasireversible and totally irreversible charge transfer processes of simple electrode reactions at stationary electrodes.

Kinetic classification of metal complexes in electroanalytical speciation
TL;DR: In this article, the Brinkman-Los equation for pulse polarographic kinetic currents appears to be more satisfactory than the classical reaction layer theory, and a reasonable estimation can be made of the bulk concentrations of both types of complexes.
