1. Overview of modern polarographic and voltammetric methods (tast polarography, normal pulse polarography, and voltammetry, differential pulse polarography and voltammetry, adsorptive stripping voltammetry).

2. Relationship between structure and electrochemical activity of organic substances (overview of polarographically active functional groups, Hammet correlation, types of electrodes suitable for the determination of different types of organic substances).

3. Voltammetry at mercury electrodes ( classical dropping mercury electrode, static mercury drop electrode, hanging mercury drop electrode, mercury film electrode).

4. Voltammetry at solid electrodes (rotating disk electrode, glassy carbon electrodes, carbon paste electrodes, chemically modified electrodes, solid amalgam electrodes, diamond film electrodes, microelectrodes).

5. Development of new methods for polarographic and/or voltammetric determination of organic substances (optimization of base electrolyte, potential program, estimation of basic analytical parameters).

6. Mechanism of electrode reactions and its analytical implications (elucidation of electrode process mechanism, basic diagnostic criteria, investigation of reversibility, determination of number of electrons exchanges, influence of mechanism on analytical parameters).

7. Examples of practical applications (non-aqueous media, preliminary derivatization, preliminary separation, measurements in flowing systems, analysis of biological and environmental samples).
