Dye and salt rejection performance of the membranes. a Pure water flux of the TpTGCl@CNFs-X/PAN membranes as a function of pressure. b Permeance and rejection of the TpTGCl@CNFs-3/PAN membrane for the nanofiltration of different dye solutions (dye concentration: 100 ppm; applied pressure: 0.2 MPa). c Permeance and rejection of the TpTGCl@CNFs-4/PAN membrane for the nanofiltration of different salt solutions (salt concentration: 1000 ppm; applied pressure: 0.4 MPa). d Comparison of the permeance and rejection of the TpTGCl@CNFs-4/PAN membrane and the representative membranes in the literatures for rejecting Na2SO4. Error bars represent standard deviations for 3 measurements
