Stability of MOPM-Fe3+/PAN membranes. a Five-stage antifouling measurement of MOPM-Fe3+/PAN membrane with 1000 ppm of sodium alginate (SA), humid acid (HA) and bovine serum albumin (BSA) solution as feed at 1.0 bar. b Stability performance of MOPM-Fe3+/PAN membrane under varied pH conditions by immersing membrane in HCl and NaOH solution for 24 h. T = 18 °C. c Long-term water stability of MOPM-Fe3+/PAN membrane (pH = 4.0). d Long-term filtration performance of MOPM-Fe3+/PAN membrane at 0.5 bar. Inset in d: Permeation flux of MOPM-Fe3+/PAN membrane in pressure cycling experiment. Error bars represent standard deviations for 3 measurements
