Abstract

Abstract:

Two promising preparationmethods of ferrite nano-materials， such asMFe₂O₄，M=Mn， Zn， Co， Ni， La， etc.， including sol-gelmethod and nanocastingmethod are introduced. The advantages and disadvantages of each method are summarized. At the same time， their application to the removal of Cr（Ⅵ） from wastewater by using ferrite is discussed. The application prospects of the ferrite nano-materials as future wastewater treatment agents are predicted.

Key words: nano-materials, ferrite, wastewater treatment
