The removal percentage of IO₃⁻ under the condition of pH 7 (a) and pH 2 (b) after β irradiation compared with the original Ce(IV)-MOF-808 sample (Conditions: contact time = 12 h, [I]_initial = 200 mg·L⁻¹, m_sorbent/V_solution = 1 g·L⁻¹). The removal percentage of IO₃⁻ by Ce(IV)-MOF-808 from the simulated Hanford groundwater (c) and Beishan groundwater (d) (Conditions: contact time = 12 h, [I]_initial = 1 mg·L⁻¹). Dynamic adsorption curve of Ce(IV)-MOF-808-packed column for IO₃⁻ capture from the simulated Hanford groundwater (e) and Beishan groundwater (f) (Conditions: [I]_initial = 1 mg·L⁻¹, m_sorbent = 200 mg, flow rate = 0.15 mL·min⁻¹).
