Advanced Oxidation Processes (AOPs) for the Degradation of Micro and Nano Plastic

Abstract

Micro-nano plastics, or MNPs, are a growing concern due to their widespread presence in the environment. To tackle this issue, advanced oxidation processes (AOPs) offer promising solutions. The focus on employing advanced oxidation processes (AOPs) to remove microplastic nanoparticles (MNPs) from water is increasing among scientists. This study compiles advancements in various AOPs such as photocatalysis, UV photolysis, ozone oxidation, electrocatalysis, Fenton oxidation, plasma oxidation, and persulfate oxidation for MNPs removal. It covers oxidation mechanisms, reaction pathways, removal efficiencies, and influencing factors. However, most AOPs achieve only modest mineralization rates, necessitating further optimization for improved performance. Exploring different AOPs is crucial for complete MNPs breakdown in water, highlighting the future importance of AOPs in MNP elimination
