采用共沉淀法在不添加任何模板剂的情况下成功制备了由纳米棒组成的羟基磷灰石（HAP）微球。我们提出的微球的形成机制是一个四步过程的基础上，其形态的演变作为反应时间的函数。我们研究了HAP微球对Pb2+、Cu2+、Cd2+、Zn2+和Ni2+的竞争吸附，表明HAP微球对废水中的Pb2+具有高选择性吸附。
Hydroxyapatite (HAP) microspheres composed of nanorods have successfully been prepared by a facile co-precipitation method without any template. We propose the formation mechanism of the microspheres to be a four-step process on the basis of the evolution of their morphology as a function of reaction time. We investigate the competitive sorption of the HAP microspheres for Pb2+, Cu2+, Cd2+, Zn2+, and Ni2+ to show that HAP microspheres are a highly selective adsorbent for Pb2+ in wastewater.
