During electrolysis with β-PbO2anodes in acidic sulfate electrolytes high current efficiencies of peroxodisulfate are obtained (60-70%) when high amounts of fluoride (1 Mol · 1-1to 3 Mol · 1-1) are added to the electrolyte. This reaction is examined by means of current efficiency of peroxodisulfate, rate of ozone formation, polarization curves, and impedance measurements. The reason for the high current efficiencies is the formation of fluorosulfonic acid in the electrolyte and its reaction with the OH-radical (from the discharge of H2O) to form HSO4-radicals. |
