A novel method, ultra-frequency induction heating and hydrothermal treatment composite method, was applied to load hydroxyapatite (HA) onto porous titanium substrate. The composition, microstructure, and morphology of as-achieved HA were characterized by XRF, XRD, FTIR and SEM. The adsorption ability of Pb2+, Cr2+ and Ni2+ was measured by ICP. The results show that HA possesses lots of carbonate groups in its lattice, and the absorption of Pb2+, Cr2+ and Ni2+ could reach 97.5%, 97.3% and 97.6%, respectively.
