Magnetic mesoporous carbon(MMC) and hydroxyapatite(HAP) composite materials with different mass ratios were prepared by co-precipitation method(MMC@HAP-x x=1, 4, and 6), and used for the removal of radioactive U(Ⅵ) in aqueous solution. The structure, functional groups and surface potential of the MMC, HAP and MMC@HAP-x were characterized by XRD, FT-IR, Zeta. The kinetics, thermodynamics, and the mechanism of MMC@HAP-x adsorption of U(Ⅳ) by the aforementioned materials were systematically studied. The results show that the optimal pH of MMC@HAP-x for U(Ⅵ) is 4.0, and the time required to reach adsorption equilibrium is less than 10 min. The theoretical saturated adsorption capacity of MMC@HAP-6 is 1 164.62 mg/g, and the adsorption process is a spontaneous chemisorption process. The fixation of U(Ⅵ) in MMC@HAP-x is due to the interaction between HAP and $\mathrm{UO}_{2}^{2+}$ to form Ca(UO2)2(PO4)2·3H2O. MMC@HAP-6 is a fast uranium adsorbent with the potential to be used for the removal of uranium from radioactive wastewater.
