Research on the adsorption of Pb2+ by apatite ore and purified apatite ore

Apatite ore from Lao Cai province (Viet Nam) has large reserves and low cost which was purified by a simple chemical method. Apatite ore and purified one were characterized for their molecular structure, phase component, specific surface area, element component, and morphology by Infrared (IR), X-ray Diffraction (XRD), Brunauer-Emmett-Teller (BET), Energy Dispersive X-ray (EDX), and Scanning Electron Microscope (SEM) methods.
