* Researchers developed high-flux nanofiltration membranes by incorporating these modified carbon nanotubes into polyamide thin-film composites, resulting in improved water permeability.
* The optimized membrane exhibited a pure water permeability rate of 15.32 L m(-2) h(-1) bar(-1), which is significantly higher than traditional membranes, while also showing effective salt rejection for various multivalent cations, making it useful for water softening and heavy metal ion removal.
