Removal of aqueous Cu 2+ ions with Fe 0 /C ceramsites fabricated by direct reduction roasting of magnetite, coal, and paper mill sludge

The porous metallic iron/carbon (Fe /C) ceramsites, with virtues of low cost and 'green' fabrication, were prepared by direct reduction roasting of magnetite, coal, and paper mill sludge. The X-ray diffraction data revealed that Fe was generated in situ by reducing the magnetite at 1,200 °...

Zusammenfassung:	The porous metallic iron/carbon (Fe /C) ceramsites, with virtues of low cost and 'green' fabrication, were prepared by direct reduction roasting of magnetite, coal, and paper mill sludge. The X-ray diffraction data revealed that Fe was generated in situ by reducing the magnetite at 1,200 °C. Scanning electron microscopy with energy-dispersive X-ray spectroscopy indicated that Fe particles, with a size of
