| Title | The Influence of High Concentrations of Fluoride on the Electrosynthesis of Peroxodisulfates at /?-Pb02 Anodes  | ||
| Abstract | During electrolysis with /?-Pb02 anodes in acidic sulfate electrolytes high current efficiencies o f peroxodisulfate are obtained (60—70%) when high amounts o f fluoride (1 M o lT '1 to 3 M ol • I"1) are added to the electrolyte. This reaction is examined by means o f current efficien cy o f peroxodisulfate, rate o f ozone form ation, polarization curves, and impedance measure ments. The reason for the high current efficiencies is the formation o f fluorosulfonic acid in the electrolyte and its reaction with the OH-radical (from the discharge o f H 20) to form H S 0 4-radicals. | ||
