The kinetics of anodic processes on Pt/PtO and PbO 2 anodes has been studied in water solutions of acetic acid.The addition of sulfuric acid has a catalytic effect in the electrochemical synthesis of peroxyacetic acid.The choice of promoters of peroxide-particles formation has been proved.I -, Cl -(current efficiency is 1.2-1.5 %) particles have been defined as the most effective for platinum anode and I -, F -(current efficiency is 0.50-0.55%) have been defined as the most effective for lead-dioxide anode.
