Abstract Recent work on the electrochemistry of technetium is reviewed, covering the period 1973–1980. Topics include polarographic studies of aqueous pertechnetate, coulometric studies of aqueous pertechnetate at mercury cathodes, and electrochemistry of pertechnetate at solid electrodes. A review is also given of electrochemistry of other technetium compounds, non-acueous systems, chemical redox reactions. and substitution reactions. Consideration is also given to studies of electrochemistry at tracer concentrations, electrolytic syntheses, standard electrode potentials, and electroanalytical methods.
