A Breakthrough curves of E2. B Specific adsorbed mass \({q}_{{{{{{\rm{ads}}}}}},{{{{{\rm{A}}}}}}}\) vs. permeate volume \({V}_{{{{{{\rm{p}}}}}}}\). The dotted line in A indicates where \(c/{c}_{0}\) = 1. The dashed line and grey box in B indicate the adsorbed mass by MF and error bar at 100 mL. Carbon nanotube pore diameter 1.7 nm, 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.
