Tailoring Interactions of Random Copolymer Polyelectrolyte Complexes to Remove Nanoplastic Contaminants from Water
AI summary Read the abstract
Researchers developed oppositely charged random copolymer polyelectrolyte complexes and demonstrated their ability to quantitatively remove nanoplastic contamination from aqueous solution, finding through computational simulations and quartz crystal microbalance experiments that hydrophobic nanostructures play a central role in the remediation mechanism.
We investigate the usage of polyelectrolyte complex materials for water remediation purposes, specifically their ability to remove nanoplastics from water, on which there is currently little to no prior research. We demonstrate that oppositely charged random copolymers are effective at quantitatively removing nanoplastic contamination from aqueous solution. The mechanisms underlying this remediation ability are explored through computational simulations, with corroborating quartz crystal microbalance adsorption experiments. We find that hydrophobic nanostructures and interactions likely play an important role.

Nanoplastics Removal from Water using Metal–Organic Framework: Investigation of Adsorption Mechanisms, Kinetics, and Effective Environmental Parameters
AI summary Read the abstract
Researchers developed a metal-organic framework material that can remove 96% of nanoplastics from water through an adsorption process. The material works by attracting the negatively charged nanoplastic particles to its surface through electrostatic forces and can be regenerated for repeated use. This technology could provide a practical solution for removing the tiniest and most dangerous plastic particles from drinking water.
