Photocatalytic efficiency of CuFe2O4 by supporting on clinoptilolite in the decolorization of acid red 206 aqueous solutions
Authors
Abstract
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). Photocatalytic degradation of acid red 206 in water was studied. CuFe2O4 was supported on Clinoptilolite using solid-state dispersion (SSD) method. The results show that the CuFe2O4/zeoliteis an active photocatalyst. The maximum effect of photodegradation was observed at 10 wt. %CuFe2O4, 90 %wt. Clinoptilolite. 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.
