Polymerizable viscous additive-assisted interfacial polymerization enables superior micropollutant/mineral selective separation in nanofiltration membranes for sustainable water purification. (PubMed, J Hazard Mater) - Oct 7, 2026 - "The optimized SINF membrane achieved an OMP/mineral (eltrombopag/Ca2+) separation factor of 652.0, 41.2 times higher than that of the control membrane, while maintaining a high water permeance of 29.2 L m-2 h-1 bar-1 and an uncompromised Na2SO4 rejection of 98.7%...Enhanced OMP rejection was attributed to strengthened electrostatic exclusion of negatively charged OMP and enhanced hydration layer interaction of hydrophobic OMP. This work provides a robust strategy for designing NF membranes that integrate rapid water transport, strong OMP rejection, and mineral ion preservation for high-quality reclaimed water production."
