Ion separation is essential for resource recycle, wastewater treatment, and lithium extraction. Thin film composite (TFC) nanofiltration membranes have recently been applied in the mono/divalent ions separation. However, TFC fabricated between polyethyleneimine (PEI) trimesoyl chloride (TMC) usually show a small water permeance. Herein, piperazine (PIP) added PEI aqueous phase solution to fabricate polyamide (PA) layer enhancement of Meanwhile, diffusion speed PIP two-phase interface slowed down by hydrogen bond effect MPDTp COFs interlayer, which can weaken reaction TMC maintain high ion rejection. The pure permeance obtained PA/Fe-COF/PES membrane 16.1 L m-2 h-1 bar-1, Li+/Mg2+ factor 73.0, almost twice as much PA/PES under mass ratio 1:20. Besides, other performances, including Na+/Mg2+, Cl−/SO42−, Na+/Ca2+, ten days long-term testing are also measured. always keeps satisfactory performance. Therefore, this work raises new strategy prepare high-efficiency membrane.
