Abstract
In this paper, strontium hydroxyapatite (Sr5(PO4)3(OH), SrHAp) nanorods were synthesized by a hydrothermal method and utilized for immobilization of Pb2+ from acidic aqueous solutions. The SrHAp nanorods exhibited a high immobilization capacity of 1482±137mgg−1 for Pb2+ in acidic solutions (pH=2.5) within 15min. The SrHAp nanorods could selectively immobilize Pb2+ with little immobilization effect on other co-existing metal ions when they were used to treat highly acidic nonferrous metallurgy wastewater (pH=1.1). The XRD, SEM, EDX and XPS results revealed that the immobilization of Pb2+ by the SrHAp nanorods was mainly due to ion exchange and Pb2+ precipitation.
