In this paper,The surface of purified attapulgite was deposited with nano-Fe3O4 particles in the open air at 80oC; the composite materials were characterized by XRD, TEM and magnetometer. It is favorable for the attapulgite to be encapsulated completely by the Fe3O4 particles as attapulgite concentration is 6g/L at pH 6.7. The films exhibited ferromagnetic behavior with Coercivity (Hci) 192.24 G, Magnetization (Ms)1.4998 emu/g, Retentivity (Mr) 0.24287 emu/g.
Keywords:Attapulgite; Magnetic Surface Modification, Nano-Fe3O4
