摘要：

Metal-organic frameworks (MOFs) MIL-101(Cr)-PMIDA with phosphate groups were prepared for the adsorption of U(VI). The morphology and structure of the samples were characterized by SEM, TEM, FT-IR, BET, XPS and XRD. This study investigated the effects of the initial U(VI) concentration, contact time, pH, adsorption temperature and coexisting ions on the adsorption of U(VI) by MIL-101(Cr)-PMIDA. The experimental results showed that the adsorption capacity of MIL-101(Cr)-PMIDA was 267.92 mg g−1 at C0 (U) = 40 mg L−1, pH = 6.0 and T = 298 K, whi...
