Basic principles of electroanalytical methods and their classification. Theoretical background and systematic, critical description of the most important methods, i.e., equilibrium (potentiometry), steady-state (polarography, voltammetry, coulometry), non-steady state voltammetry, bulk solution measurements (conductometry, impedance measurements), flow detection and continuous monitoring, combinations of electrochemical measurements with high-performance separations and with other physico-chemical techniques (spectroscopy). Typical examples of applications.

1) Introduction. Basic principles of electroanalytical methods and their classification.

2) Theoretical background: basic terms, electrochemical properties of solutions, mechanism and rate of electrochemical processes (charge transfer reaction, transport mechanisms, homogeneous and heterogeneous chemical reactions coupled with electrode reactions, adsorption of compounds from solution or produced by electrochemical reaction on the electrode surface).

3) Equilibrium potentiometry: galvanic cell, electrodes, ion-selective electrodes, pH measurement, potentiometric gas sensors. Indirect potentiometry - potentiometric titrations.

4) Polarography: classical polarography, types of polarographic currents, diagnostic criteria, various kinds of mercurial electrodes, analytical applications.

5) Modern polarographic and voltammetric methods: Tast polarography, normal pulse and differential pulse polarography, anodic stripping analysis, adsorption stripping analysis.

6) Non-stationary methods: dc-voltammetry, cyclic voltammetry.

7) Voltammetry with solid electrodes: properties of electrodes from solid materials, typical polarization curves, electrode history elimination, rotating disk electrode, rotating ring-disk electrode. Microelectrodes and their arrays.

8) Conductometry: low-frequency conductometry, two- and four-electrodes conductometric cells, contactless conductometry, high-frequency conductometry and dielectrometry.

9) Electrochemical methods in flowing systems.

10) Methods based on exhausting electrolysis: potentiostatic coulometry, galvanostatic coulometry, coulometric titrations, coulometry in flowing systems, thin-layer coulometry.

11) Titrations with polarizable electrodes: amperometric titrations, biamperometric titrations, bipotentiometric titrations, potentiometric titrations with one polarizable electrode.
