摘　　要：以羟丙基甲基纤维素(HPMC)为软模板,制备了碳羟基磷灰石纳米球,用能谱分析(EDS)、红外光谱(FT-IR)、透射电镜(TEM)及X射线衍射(XRD)等实验手段对产物进行了相关表征,研究了羟基磷灰石纳米球对废水溶液中镉离子的去除行为。研究表明,所制备的碳羟基磷灰石为球形晶体,平均直径为20～30nm,且分散均匀,其对含镉废水的净化能力明显高于市售粉体羟基磷灰石。Spheric nano-particle carbonate-hydroyapatite （CHAP） was synthesized using HPMC as template and characterized by fourier transform infrared spectroscopy （FT-IR）, transmits electron microscopy （TEM）, X-ray diffraction （XRD） and energy depressive spectroscopy （EDS）. The result indicates that the diameter of nano-particle is about 20-30nm and the specific surface area is about 95. 6m^2/g. It was found that the removal efficiency of aqueous cadmium is promoted successfully by spheric nano-particle carbonate-hydroyapatite compared to normal hydroxyapatite only.
