ClearAdvanced Oxidation Techniques and Hybrid Approaches for Microplastic Degradation: A Comprehensive Review
This review examines advanced oxidation processes for degrading microplastics, including photocatalysis, electrochemical oxidation, Fenton reactions, and plasma technologies, which generate reactive species capable of breaking down polymer chains. Hybrid systems combining these oxidation methods with biological treatments or membrane filtration showed particular promise for scalable microplastic remediation. The authors identify challenges around energy consumption, secondary pollutant formation, and the need for optimization before these technologies can be integrated into existing wastewater treatment infrastructure.

Chemical methods to remove microplastics from wastewater: A review
This review examines three chemical approaches for removing microplastics from wastewater: coagulation (clumping particles together), electrocoagulation (using electrical current), and advanced oxidation (breaking plastics down chemically). Each method has strengths and weaknesses in terms of cost, effectiveness, and potential byproducts. The research is important because wastewater treatment plants are a major pathway through which microplastics reach rivers, lakes, and ultimately human drinking water sources.

Advanced oxidation in the treatment of microplastics in water: A Review
Researchers reviewed how advanced oxidation processes (AOPs) — chemical methods that generate highly reactive molecules — can break down microplastics in water rather than simply filtering them out. Unlike traditional treatment that just moves microplastics around, some AOPs can fully convert plastic fragments into carbon dioxide and water, making them a promising frontier for actual microplastic destruction in water treatment.
