a, Pure water permeance and CR rejection of commercial GC-NF5001, TCM and SNFM. b, Performance of commercial GC-NF5001, TCM and SNFM in the presence of various active aqueous molecules. c, Comparison of the separation performance of commercial GC-NF5001, TCM and SNFM with state-of-the-art membranes: MPCM (molecularly porous cross-linked membranes)43, GO-TBO (graphene oxide-toluidine blue O)44, QL-COF (4-carboxyl-quinoline linked covalent organic frameworks)45, PGO (porous graphene oxide)46, ZIF-8/GO (zeolitic imidazolate framework-8/graphene oxide)47, TFCM (thin-film composite membranes)24, MOA (self-assembled multiblock oligomer amines)48 and salt-mediated polyamide49 for removing CR from water. d, Permeance and separation factor of commercial GC-NF5001, TCM and SNFM for CR and salts. e, Effects of different CR concentrations in aqueous CR/NaCl solution on membrane performance. f, Operational stability of commercial GC-NF5001, TCM and SNFM in a CR/NaCl aqueous solution. Inset: a schematic diagram of the SNFM inhibiting pollutant adsorption. Error bars in a, b and d–f represent the s.d. (n = 3, n derived from different experimental units), and data are presented as mean values ± s.d.
