Beschreibung
Zusammenfassung:	The invention discloses an ordered mesoporous material loaded nano zero-valent iron material (Al-MCM-41 (at) nZVI) as well as a preparation method and application of the ordered mesoporous material loaded nano zero-valent iron material (Al-MCM-41 (at) nZVI). The ordered mesoporous material is an ordered mesoporous material (Al-MCM-41) synthesized by taking calcined alkaline leached attapulgite as a silicon source and taking cetyltrimethylammonium bromide (CTAB) as a template agent, and the Al-MCM-41 (at) nZVI is prepared by taking Al-MCM-41, ferric chloride hexahydrate (FeCl3. 6H2O) and sodium borohydride (NaBH4) as main raw materials; compared with unloaded nano zero-valent iron (nZVI), the Al-MCM-41 (at) nZVI new material synthesized by the method keeps the reducibility, high surface energy and other properties of the nano zero-valent iron, increases the stability of the nano zero-valent iron in the environment, overcomes the defects that the nano zero-valent iron is easy to agglomerate, easy to oxidize and
