Abstract

Complex organic pollutants in pharmaceutical wastewater exhibit high toxicity and refractory properties. Electrolytic oxidation technology has become an important means for treating such wastewater due to its high efficiency. As a key reactive species in the electrolytic oxidation process, chlorine radicals play a core mediating role in pollutant degradation. By analyzing the generation mechanism of chlorine radicals, their reaction sites with pollutants, and the transformation rules of degradation intermediates, the pathway of pollutants from complex structures to gradual mineralization can be clarified. Elucidating the chlorine radical-mediated degradation pathway can provide theoretical support for optimizing electrolytic oxidation process parameters and improving pollutant removal efficiency, which is of great significance for promoting the development of harmless treatment technologies for pharmaceutical wastewater.
