Microplastics Degradation in Water: A Review of Advanced Oxidative Processes and Ozonation for Effective Treatment

Asian Journal of Chemistry 2025
Lukusa Cimanga, Viswanadha Srirama Rajasekhar Pullabhotla

Summary

This review examines advanced oxidative processes (AOPs) and ozonation as emerging technologies for degrading microplastics in drinking water and aquatic environments, covering both identification and quantification methods alongside treatment efficacy. The authors assess the challenges and capabilities of these approaches in addressing the growing concern over microplastic contamination in water supplies.

Study Type Environmental

In the backdrop of the increasing microplastics (MPs) production and the global concern into the emergence of pollution, a pressing need to develop extensive implementations of the advanced oxidative processes (AOPs) is in the rise. In line with this, the challenges and competencies of MPs degradation techniques including the identification and quantification technologies used in drinking water and wastewater treatment procedures were analyzed. Assessment of the MPs degradation techniques has shown that photocatalytic processes, Fenton systems and the electrochemical oxidation processes present more challenges than ozone-based technology. Given a much greater solubility of ozone in water that surpasses oxygen, its vigorous reactive properties and the ozone reliable generation, we propose a steady application of ozonation reactions more especially in the disinfection of drinking water, industrial wastewater and river water pharmaceuticals pollution treatment.
