چکیده

In this paper CuFe₂O₄, nanocrystalline powders were prepared. Also, the supported Cu ferrite was obtained by impregnation of the supports with Cu and Fe nitrates solutions, for calcination temperature 450 ºC. The samples were characterized by X-ray powder diffraction (XRD) and Fourier transform-infrared spectroscopy (FT-IR). In this investigation photocatalytic degradation of Acid red 206 in water was studied. The results show that the CuFe₂O₄ is an active photocatalyst. A first order reaction with k = 0.123 min^-1 was observed. The effects of some parameters such as pH, amount of photocatalyst, initial concentration of dye were examined.
