Current Approaches and Challenges in Advanced Oxidation Processes for Nanoplastic Degradation

The proliferation of plastic production has led to a surge in nanoplastics (NPs) pollution, posing significant environmental and health risks. Despite efforts to mitigate plastic waste, NPs persist as a significant challenge due to their small size, high surface-to-volume ratio, and complex nature. This review explores advanced oxidation processes (AOPs) as promising techniques for NP remediation, including ozonation, electrochemical, photocatalytic, and plasma-induced processes. Existing research is analyzed to investigate the performance of AOPs in NP degradation. Gaps in the development of effective processes and analytical methods are highlighted, and future directions are suggested. This review aims to enhance understanding and promote sustainable solutions for the remediation of NPs from contaminated water resources in alignment with the objectives outlined in the sixth Sustainable Development Goal set by the United Nations.
