In this paper, the preparation method for photocatalyst nano ferrite (represented by ZnFe204 and BiFe03) and its application in wastewater treatment are reviewed. The catalytic characteristics of ferrite are studied and the effects of process conditions on the degradation rate of organic pollutants are discussed, such as initial reaction pH, initial pollutants concentration,H_2O_2 addition,and so on. The reaction mechanism of photo Fenton-like oxidation is introduced. Finally,the problems in application of nano ferrite in wastewater treatment are summarized and the development directions are proposed. |
