    摘要:

    研究了以多孔鈦為基體，采用超高頻感應(yīng)熱/水熱法負(fù)載HA涂層的新方法，借助XRF、XRD、FTIR、SEM等手段對HA的成分、結(jié)構(gòu)及形態(tài)進(jìn)行了表征，并運(yùn)用ICP考察其對水溶液中Pb2+，Cr2+，Ni2+的吸附作用。結(jié)果表明，所制得的HA晶格中含有大量碳酸根，對Pb2+，Cr2+，Ni2+的吸附效率分別達(dá)到97.5%、97.3%、97.6%。

    Abstract:

    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.
