A Magnetically Recoverable Fe3O4–NH2–Pd Sorbent for Capture of Mercury from Coal Derived Fuel Gas

Abstract A sort of magnetical material named Fe3O4–NH2–Pd was prepared by loading varying amounts of immobilizing Pd on the surface of the magnetic Fe3O4–NH2 microspheres. This magnetical material was used firstly for capturing Hg° from coal derived fuel gas based on its recoverability. The experime...
