ELECTROSYNTHESIS OF AMMONIUM PERSULFATE AT A GLASSY-CARBON ANODE

The technology of ammonium persulfate production at anodes from glassy carbon produced by domestic industry is under development. The additi on of a fluoride additive into electrolyte is shown to improve corrosi on and electrochemical properties of a glassy carbon anode. Effect of fluoride and sulfate ion concentrations as well as pH on the kinetics and selectivity of ammonium persulfate formation and anode corrosion r esistance is studied. The possibility of replacing the filtering diaph ragm, which is used in ammonium persulfate production, with a MF-4SK c ation-exchange membrane is investigated.
