Broad-spectrum rejection of emerging organic contaminants with different structures and properties from complex water matrices by a chlorine-resistant Janus nanofiltration membrane

per h per bar) and rejection of tobramycin, 3,3,5,5-tetrabromobisphenol A, heptadecafluorononanoic acid and tris(2-phenylphenyl)phosphate (over 99.9%). Additionally, the JM200 membrane exhibits outstanding antibiotics/salt selectivity (separation factor of tobramycin/NaCl = 152), anti-fouling, chlorine resistance (chlorine exposure of 400 000 ppm min) and stability, delivering superior performance compared to the commercial NF270 membrane during long-term treatment of real surface water and municipal wastewater. This study opens a sustainable avenue for ultrafast and broad-spectrum removal of EOCs from complex water matrices with low energy and chemical consumption.
