Abstract

DSA anode is one of the most advanced types of electrode plates in the electrochemical industry at present. With its low chlorine evolution potential and strong corrosion resistance, the DSA anode plays a prominent role in many electrode plates. In this paper, four kinds of DSA electrode plates (ruthenium iridium electrode, iridium tantalum electrode, tin antimony electrode, and platinum electrode) were selected for electrochemical in-situ analysis. Their macroscopic chlorine evolution performances were explained microcosmically by the LSV curve, CV curve, Tafel curve, and AC impedance curve. The results show that the ruthenium iridium coated electrode plate has the lowest chlorine evolution potential, the highest current density, the largest electrochemical active area, the fastest kinetic speed, the lowest heat loss, and the smallest coating liquid surface impedance, so the macro performance is the strongest chlorine evolution ability.
