The course aims to provide theoretical insight into basics of electrochemistry and into commonly occurring modern electroanalytic techniques (conductometry, potentiometry, polarographic and voltammetric methods, amperometric and coulombic methods). Their utilization in inorganic and organic analysis will be emphasized. The lecture is taught in English, Erasmus students can participate. Last update: Schwarzová Karolina, doc. RNDr., Ph.D. (24.01.2022)

1) Review of the basics of electrochemistry (electrical properties, electrode and electrode processes - oxidation, reduction, electrical double layer, electrochemical cell - galvanic and electrolytic cell, electrolysis, two electrode and three electrode setup, indicator, auxiliary and reference electrodes, definition of electroanalytical methods and their classification). 2) Potentiometry (potential, voltage, Nernst equation, standard potential, potential measurements, pH electrodes and pH measurements, ion selective electrodes, potentiometric titrations). 3) Conductometry (electrolytical mobility, individual ionic conductivity, molar conductivity of electrolytes, Kohlrausch law, conductometric titrations). 4) Voltammetric methods (polarography and voltammetry - basic principles, instrumentation and methods. Ilkovic equation, diffusion, kinetic, catalytic and capacity currents, logarithmic analysis. Voltammetry in quiescent solutions - DC voltammetry, pulse techniques, adsorptive stripping techniques. Cyclic voltammetry. reversible and irreversible processes. Indicator electrodes - mercury-based and carbon-based, chemically modified electrodes. Hydrodynamic voltammetry - rotating disc electrode. 5) Amperometric and coulombic methods (principles of amperometry and coulometry, Faraday`s law, controlled potential and constant current coulometry, coulometric titration. Hyphenation of liquid-flow techniques with electrochemical detectors)
