Comparative studies of adsorption on PAN/AO-SBA-15 and PAO/AO-SBA-15 membranes with other reported adsorbents in U (VI) water or simulated wastewater [81]. a: Adsorption capacity is calculated by qm·S/m, where qm is the maximum adsorption capacity (mg/m2), S is the membrane area (m2), and m is the mass (g) of the membrane before adsorption.
