(a) Effect of ionic strength on removal of U(VI) by Fe3O4@SiO2@UiO2-66-TPP NPs (C0 = 100 mg/L, m/V = 0.4 g/L, pH = 5.0 ± 0.1, and T = 298 K). (b) Effect of competitive ions on the selective sorption of U(VI) onto the sorbent (C0 = 0.5 mmol/L for all ions, pH = 5.0 ± 0.1, T = 298 K, V = 25 mL, t = 60 min, and m = 10 mg).
