摘要：
Electrochemical oxidation of ammonium (NH4+) at Ti/PbO2 anode in chloride-free and chloride containing aqueous solutions was studied. The experimental results have shown that oxidation of NH4+ is ensured only in the presence of chloride. The oxidation of NH4+ is found to follow pseudo first-order kinetics. Bromide in the electrolyte is found to cause substantial rate enhancing effect on the ammonium removal. The dependence of k on the current density as well as halide concentration is also discussed in this study.
