铁酸盐纳米材料的制备及其处理Cr(Ⅵ)的研究现状

Preparation of ferrite nano-materials and their present application to the treatment of Cr(Ⅵ)

阐述了制备铁酸盐纳米材料(MFe2O4,M为Mn,Zn,Co,Ni,La等)的两种方法,包括溶胶-凝胶法、纳米刻蚀法,评述了每种制备方法的优缺点。论述了用铁酸盐纳米材料去除污水中Cr(Ⅵ)的方法,展望了铁酸盐纳米材料作为未来污水处理剂的应用前景。

Two promising preparation methods offerrite nano-materials, such as MFe2O4, M=Mn, Zn, Co, Ni, La, etc., including sol-gel method and nanocasting method are introduced. The advantages and disadvantages of each method are summarized. At the same time, their application to the removal ofCr（Ⅵ） from wastewater by using ferrite is discussed. The application prospects of the ferrite nano-materials as future wastewater treatment agents are predicted.
