Enzyme-triggered coatings of tea catechins/chitosan for nanofiltration membranes with high performance

We report a completely green and one-step protocol to fabricate selective layers for thin film composite nanofiltration membranes via the laccase-triggered co-deposition of natural tea catechins and chitosan. The constructed membranes show around 99% rejection of Na2SO4 with a high water permeation...

Zusammenfassung:We report a completely green and one-step protocol to fabricate selective layers for thin film composite nanofiltration membranes via the laccase-triggered co-deposition of natural tea catechins and chitosan. The constructed membranes show around 99% rejection of Na2SO4 with a high water permeation flux of 45 L m-2 h-1 under 0.6 MPa.
