A research team has developed an iron-modified titanium dioxide electrode that substantially improves the breakdown of nitrobenzene, a persistent wastewater pollutant. In a laboratory reactor combining electrical treatment, heat and ultraviolet light, the system removed 92.1% of nitrobenzene within two hours. A nitrate-based calculation indicated 62.4% mineralization over the same period, showing that breakdown had advanced substantially but remained incomplete. The findings suggest a way to make combined treatment systems more effective and guide the design of electrodes for removing difficult organic contaminants from wastewater.
