Novel,low-cost Fe0/ZSM-5-based particles and porous tablets were prepared by a ball-milling method and used for the removal of Pb2+ in solution.Solid-phase characterization by scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEMEDS) and transmission electron microscopy (TEM) revealed that the Fe0 microparticles were evenly loaded and tightly immobilized on the surface of ZSM-5 because of the extrusion/welding impact during ball-milling.For different Pb2+ concentrations,batch experiments indicated that the removal of Pb2+ increased with the decline of dissolved Fe2+ and pH value in the solution for particles;opposite results were obtained for the tablets.The differences in the contact between both materials and Pb2+ were the main factor controlling Pb2+ removal in the solution.Investigation into the effect of initial pH value revealed that high pH reduced the number of electrons released from Fe corrosion.Consequently,low levels of removed Pb2+ and dissolved Fe2+ were synchronously observed.Also,simulated electroplating wastewater was treated using the prepared particles and porous tablets,and the removal order of Pb2+ > Cr6+ > Cu2+ ≈ Cd2+ was observed.The Fe0/ZSM-5 particles and tablets prepared through ball-milling show potential as materials for treatment of Pb2+ and other toxic metals.
