Study and optimize the conditions for the synthesis of Fe3O4 doping of PbO.The synthesized and characterized Fe3O4 doping of PbO (PbO/Fe3O4) was optimized and then was used for studying the adsorptive removal of heavy metal ions Pb2+. The adsorption kinetics was analyzed as time goes by. The adsorption efficiency was in touch with several factors, including the pH of solution, temperature and the initial concentration of Pb2+. The equilibrium adsorption characteristics at different initial concentrations of Pb2+ was investigated. It was demonstrated that the adsorption processes of Pb2+obey to a pseudo-second order model and Langmuir isotherm model.
