Hierarchical hydroxyapatite microspheres composed of nanorods and their competitive sorption behavior for heavy metal ions

Zhu, Ronghai and Lai, Xiaoyong and Halpert, Jonathan E. and Yu, Ranbo and Wang, Dan (2012) Hierarchical hydroxyapatite microspheres composed of nanorods and their competitive sorption behavior for heavy metal ions. European Journal of Inorganic Chemistry (16). pp. 2665-2668. ISSN 1434-1948

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 Pb 2+, Cu 2+, Cd 2+, Zn 2+, and Ni 2+ to show that HAP microspheres are a highly selective adsorbent for Pb 2+ in wastewater.
