Development of crosslinked polyvinyl alcohol nanofibrous membrane for microplastic removal from water
AI summary Read the abstract
Researchers developed a crosslinked polyvinyl alcohol nanofibrous membrane capable of removing microplastics and lead from drinking water. The membrane achieved over 99% removal efficiency for microplastics larger than one micrometer while maintaining good water flux, showing promise as a point-of-use filtration device.
Porous chitosan microfiltration membranes for microplastics removal
AI summary Read the abstract
Researchers made water filtration membranes from chitosan, a natural material, to remove microplastics from water. In lab tests, membranes made by one preparation method filtered out more than 99% of polyvinyl chloride microplastic particles, while membranes made by a different drying method did not work as well.
Membrane Technologies for Microplastics Removal from Wastewater: Recent Progress, Fouling Mechanisms, and Future Perspectives
AI summary Read the abstract
Tiny plastic particles called microplastics are slipping through our wastewater treatment plants and ending up back in the environment—and potentially in our food and water—because standard filtering methods aren't fine enough to catch them. This review paper rounds up the latest research on advanced filter membranes that can trap these particles more effectively, while also tackling a key problem: the membranes tend to get clogged by the plastics they're filtering out. While these technologies aren't yet perfected or widely deployed, they represent a promising step toward cleaner water and reduced human exposure to microplastics, which have been linked to potential health concerns.
Designing poly(vinylidene fluoride) membranes with narrow pore size distribution for microplastics removal from water
AI summary Read the abstract
Scientists developed an improved method for making water filtration membranes with very uniform pore sizes, specifically designed to capture tiny microplastic particles. Using a common polymer (PVDF) and a straightforward manufacturing process, the membranes achieved over 97 percent removal of microplastic particles as small as 500 nanometers. The study suggests this approach could offer a practical and scalable solution for filtering microplastics from drinking water and wastewater.
Analysis of membrane surface after the filtration of surface water containing microplastic
AI summary Read the abstract
Researchers tested ultrafiltration and nanofiltration membranes on real river water containing microplastics and found both membrane types completely removed plastic particles from the filtered water, though the deposited microplastics reduced water flow through the membranes over time — confirming membrane filtration as an effective but imperfect water treatment strategy.
