【Objective】This study aimed to effectively, rapidly , and cost-effectively purify wastewater and repair soil from lead pollution. 【Method】The remediation effect of a lead-remediation material (superparamagnetic micro nano Fe3O4@Ca10(PO4)6(OH)2 functional material, MFH) on Pb2+ in wastewater and polluted soil was studied in terms of dosage, initial concentration of Pb2+, adsorption time, pH, ionic strength and organic matter concentration. 【Result】The results showed that the adsorption of Pb2+ in solution by MFH satisfies the pseudo-second-order kinetic model. The adsorption equilibrium was reached in about 10 min, and the maximum adsorption capacity was 181.6 mg·g-1; at pH 2.00~5.00. Also, the removal rate of Pb2+ in the pH range decreased with the increase of pH while an increase in ionic strength of the solution inhibited the removal rate of Pb2+ by MFH. Nevertheless, an increase in the organic matter content in the reaction system effectively improved the removal rate of Pb2+ by MFH. MFH showed a good lead-removal effect when applied to lead-contaminated soils in farmland and industrial parks. The addition of heavy metal activator EDTA can significantly improve the removal effect of MFH on lead in soil. In slightly lead-contaminated farmland soil, the total amount of lead removed was 102.74 μg·g-1. After experimentation, the recovery rate of MFH from soil was over 88% by using a magnetic rod, while the recovery rate of MFH regeneration performance was 89.49%. Importantly, the magnetic properties and specific surface area of the regenerated MFH recovered well, suggesting that MFH had a good recovery and regeneration ability. 【Conclusion】Therefore, MFH is a good material for the decontamination of lead-contaminated wastewater and soils and its usage is promising given that it can easily be recovered with its basic properties intact.
