Preparation of porous hydroxyapatite and its application in Pb ions effective removal

Preparation of porous hydroxyapatite and its application in Pb ions effective removal

Porous hydroxyapatite (HA) matrices with high porosity were prepared through a high temperature sintering method by using HA powder as raw material, polystyrene (PS) microspheres as pore-forming agents and polyvinyl alcohol (PVA) solution as adhesive. The characterization of HA was carried out by a...

The adsorption capability for Cu2+, Cd2+ and Pb2+ in aqueous solution showed that the porous HA possessed a selective and strong uptake of Pb2+ ions and the adsorption efficiency reached 99.8% in 10 min.http://dx.doi.org/10.1063/1.5086705
