Fig. 8: Relationship between hormone adsorbed mass and pore diameter.

Specific E2 adsorbed mass of VaCNT membrane \({q}_{{{{{{\rm{ads}}}}}},{{{{{\rm{A}}}}}}}\) and logarithm of the enhancement factor (\({{{{{\rm{EF}}}}}}\)) with varied membrane pore diameters. Permeate volume 100 mL, flux 27 ± 3 L m−2 h−1, 100 ng L−1 E2, 1 mM NaHCO3, 10 mM NaCl, pH 8.1 ± 0.2, 23.0 ± 0.2 °C. Error bars represent propagated error from operational parameter variations and analytical error.
