eng Abstract:
The classical definition of polarography was "electrolysis with dropping mercury electrode (DME)". This definition characterized originally d.c. voltage-controlled method containing theoretical equations of different currents obtained with DME as well as its practical applications in analysis and in general science. Gradually, next to dropping electrode other types of mercury electrodes were used, as streaming and hanging drop. Development of the instrumental side of polarography introduced also methods of current-controlled electrolysis and beside pure mercury also amalgam electrodes. Nowadays polarography can be best characterized as physico-chemical branch of science ceveloped from simplke electrolysis with dropping mercury electrode.
