Studies on electrochemical disinfectant production using anodes containing RuO2
Özet
The present work contains results for artificial water electrolysis in discontinuous operation using laboratory reactors without separators. Rotating anodes with mixed oxide coatings containing IrO2/RuO2 were used. The experimental parameters were the chloride concentration, current density, rotation rate, cathode material, pH and water composition. Active and total chlorine concentrations and current efficiencies were obtained. It was shown that even for very low chloride concentrations, chlorine formation occurs, but side effects and side reactions significantly lower the efficiency in this case. Nitrite and ammonia formation was found to reduce the efficiency of chlorine formation. Partial polarization curves were obtained in kinetic experiments using solutions containing chloride and sulphate ions.
