Microplastics remediation in aqueous systems: Strategies and technologies
AI summary Read the abstract
This review assessed strategies and technologies for removing microplastics from aquatic environments, comparing coagulation-flocculation, membrane filtration, magnetic separation, photocatalysis, and biological degradation approaches in terms of efficiency, scalability, and cost for both wastewater and natural water treatment.
In recent years, the ubiquitous detection and accumulation of microplastics (MPs) in the aquatic environment have raised significant concerns on water security and long-term ecological impacts all around the world. Nevertheless, critical reviews on strategic control and effective remediation of MPs in the aqueous phase are still lacking. In this work, we summarise the origins and types of MPs, and then introduce the methodologies for extraction, identification and quantification. More importantly, we for the first time provide a comprehensive overview of the recent advances in the emerging MPs removal and transformation technologies. Except for biodegradation, this review presents new applications of advanced oxidation processes (AOPs) for MPs degradation and utilisation, including photocatalysis, photoreforming and Fenton-like reactions. Physical or catalytic thermal treatment can transform plastics into value-added nanocarbons or hydrocarbons. These transformation technologies demonstrate great potentials in dealing with MPs. The review will guide researchers to further explore the feasible approaches and develop new strategies for advanced control and remediation of MPs in the future.

Nano-based remediation strategies for micro and nanoplastic pollution
AI summary Read the abstract
This review covers how nanomaterial-based technologies can be used to remove microplastics from the environment, including methods using magnetic nanoparticles, photocatalysts, and membrane filters. While current physical, chemical, and biological removal methods each have limitations, nanomaterials can enhance their effectiveness by targeting smaller plastic particles that traditional methods miss. Better removal technologies could ultimately reduce human exposure to microplastics in drinking water and food.
Microplastics and nanoplastics: Recent literature studies and patents on their removal from aqueous environment
AI summary Read the abstract
This review surveyed recent research and 42 international patents on technologies for removing microplastics and nanoplastics from water, categorizing methods into filtration, capture-based, and degradation approaches. Removal efficiencies between 58% and 100% were reported across techniques including coagulation, membrane filtration, photocatalytic degradation, and microbial breakdown. The study highlights that while promising methods exist, each has limitations depending on factors like plastic type, water chemistry, and particle size.
