Subba Rao, Anantha N. | Venkatarangaiah, Venkatesha T.

Electrochemical oxidation is an effective wastewater treatment method. Metal oxide-coated substrates are commonly used as anodes in this process. This article compiles the developments in the fabrication, application, and performance of metal oxide anodes in wastewater treatment. It summarizes the preparative methods and mechanism of oxidation of organics on the metal oxide anodes. The discussion is focused on the application of SnO₂, PbO₂, IrO₂, and RuO₂metal oxide anodes and their effectiveness in wastewater treatment process.
