Summary: The electrocatalytic properties of Ti/RuO2-SnO2 and Ti/RuO2-IrO2 anodes in different electrolytes were studied for aniline degradation. Ti/RuO2-SnO2 showed higher activity in Na2SO4 electrolyte, while Ti/RuO2-IrO2 was more effective in NaCl electrolyte. The presence of Fe2+ can decrease TOC removal efficiency, especially for Ti/RuO2-SnO2.
