✦ Synopsis

This paper presents equilibrium and kinetic studies of the 0, and Q/SO, electrodes in molten NaNO,-KN03 eutcctic at 380Β°C. For the O2 electrode the overall reaction is given by the equation: *o,+Ze-= oz-.

The exchange currents for this reaction are higher with platinum than with gold and are l-2 orders of magnitude higher than those previously measured in molten sulphates.

Tbe overall reaction of the OJSO, &&rode is: s0*+0,+2e-= so:-.

Gold is a better catalyst than platinum for this reaction, quite similar to the case in molten sulphates. Molten NaNO,-KNO, seems to be an appropriate electrolyte for use in a new electrochemical flue gas desulphurization process in the temperature range of 350450Β°C.

In the electrolysis of pure molten silver nitrate with a silver cathode and a platinum anode at temperatures from 220 to 380Β°C a reversible cell is formed. When the system is electrolysed for a short time at a steady current density and then the current is interrupted, it tends to reach after a few
