Hierarchically structured microspheres self-assembled from hydroxyapatite nanorods have successfully been prepared by a simple co-precipitation method without any template. The as-prepared materials exhibit high selective adsorption for Pb2+ in wastewater.

Abstract

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.
