Innovations in chemical degradation technologies for the removal of micro/nano-plastics in water: A comprehensive review
AI summary Read the abstract
This review summarizes advances in chemical degradation technologies for removing micro- and nanoplastics from water, including photocatalysis, Fenton-based reactions, electrochemical oxidation, and micro/nanomotor approaches. Researchers analyzed the key factors that influence degradation effectiveness, such as particle properties and operating conditions. The study identifies current challenges and outlines future directions for developing practical chemical methods to address plastic pollution in water systems.
Micro/nanoplastics (M/NPs) in water have raised global concern due to their potential environmental risks. To reestablish a M/NPs free world, enormous attempts have been made toward employing chemical technologies for their removal in water. This review comprehensively summarizes the advances in chemical degradation approaches for M/NPs elimination. It details and discusses promising techniques, including photo-based technologies, Fenton-based reaction, electrochemical oxidation, and novel micro/nanomotors approaches. Subsequently, critical influence factors, such as properties of M/NPs and operating factors, are analyzed in this review specifically. Finally, it concludes by addressing the current challenges and future perspectives in chemical degradation. This review will provide guidance for scientists to further explore novel strategies and develop feasible chemical methods for the improved control and remediation of M/NPs in the future.
