Removal of Microplastic Pollutant in Surface Water Using Electrocoagulation Process with Fe Electrode
AI summary Read the abstract
Researchers evaluated electrocoagulation using iron electrodes as a method for removing microplastics from surface water, testing how electrical coagulation forces microplastic particles to aggregate and separate from the water column, offering a scalable treatment approach with minimal chemical inputs.
Microplastics (MPs) were considered as a problem due to their small size. Previous research has proved that MPs resulted in some negative impacts in a long term for human, biota, ecosystems, and environments including aquatic environment. Electrocoagulation (EC) is a...

Mechanism and Improvement of Electrocoagulation Technology for Removing Microplastics from Wastewater-Current Status and Future Directions
AI summary Read the abstract
This review analyzed electrocoagulation as a method for removing microplastics from wastewater, finding that hybrid systems combining electrooxidation or membrane filtration achieve over 95% removal efficiency through charge neutralization, sweep flocculation, and oxidative degradation. Efficient wastewater treatment is a critical intervention point for stopping microplastics from reaching aquatic environments and ultimately entering the food chain and drinking water.
The Removal of Polypropylene Microplastics in Simulated Water Enriched with Organic Substances Through the Electrocoagulation Process
AI summary Read the abstract
Researchers tested electrocoagulation as a treatment method for removing polypropylene microplastics from simulated domestic wastewater enriched with organic substances in a Peruvian context, demonstrating effective removal under controlled conditions. This approach addresses a critical gap in wastewater infrastructure in developing regions, where untreated microplastic-laden water directly contaminates drinking sources and food-producing water bodies.
Advances in electrochemical-based treatment of microplastics in wastewater: removal performance and influencing factors
AI summary Read the abstract
This review evaluates five electrochemical technologies—electrocoagulation, electrooxidation, electroreduction, bioelectrochemistry, and electrosorption—for removing microplastics from wastewater, finding each offers high efficiency with controllable operating conditions. Because conventional treatment plants miss much of the microplastic entering waterways, scalable electrochemical solutions are urgently needed to prevent these particles from reaching drinking water and marine ecosystems.
Study of the Efficacy of Electrocoagulation in the Removal of Polyethylene Terephthalate (PET) Microplastics in Synthetic Wastewater: An Experimental Approach
AI summary Read the abstract
This study tested electrocoagulation — an electrical water treatment process — for removing PET microplastics from synthetic wastewater, finding it to be an effective removal method. Electrocoagulation could offer a practical wastewater treatment upgrade to prevent microplastics from being released into rivers and drinking water sources.
Removal of microplastics from water by using magnetic sedimentation
AI summary Read the abstract
"Researchers demonstrated that magnetic Fe-C-NH2 nanoparticles added to water can attach to polyethylene and PET microplastics, forming heteroaggregates that are then removed by a gradient magnetic field, achieving effective extraction of both plastic types from model aqueous suspensions. This green magnetic sedimentation approach offers a scalable, chemical-free pathway for removing microplastics from drinking water or wastewater effluent, with direct implications for reducing human ingestion of plastic particles."
