Differential pulse and square-wave voltammetry as sensitive methods for electroanalysis applications

A brief description of differential pulse voltammetry and square wave voltammetry as the most sensitive and more used techniques for electroanalysis has been investigated in this article. According to the large literature information available for these two methods, a self-consistent description has been done firstly by giving a short introduction to the voltammetry techniques. The next step was to briefly describe the principle of these techniques supported by graphs. To make it easier to understand by the readers, practical examples of the situations where these two methods have been used for the electroanalysis were also described.
