Alginate cryogel beads for effectively aggregating nanoplastics for water remediation
Researchers discovered that alginate cryogel beads — a material derived from seaweed — can rapidly clump nanoplastics (particles smaller than 1 micrometer) into larger clusters that are easy to filter out, removing over 99% of nanoplastics in under two minutes. This simple, scalable approach could address one of the hardest parts of water treatment: catching particles too small for standard filters.
Evaluating the Role of Calcium Ions in the Removal of Nanoplastics ( 607 nm) by Flocculation‐Enhanced Sedimentation using Alginate
Researchers evaluated the role of calcium ions in enhancing nanoplastic removal from water through flocculation-sedimentation using alginate, finding that calcium promotes bridging between alginate chains and nanoplastic surfaces to improve phase separation. The study identifies calcium ion concentration as a critical parameter for optimizing nanoplastic removal in water treatment applications.
