| Abstract
|
:
|
The purification of wastewater from phenol and other phenolic compounds which are discharged from different industrial activities is an important environmental issue. Such compounds cause severe damage to the human body and to the environment. In this study, the degradation of phenol is investigated by using copper ferrite CuFe<sub>2</sub>O<sub>4</sub> catalysts. CuFe<sub> 2</sub>O<sub>4</sub> powders were prepared by two different methods: sol-gel and co-precipitation methods, and followed by thermal treatments at 500 °C and 750°C. The prepared ferrites were characterized for their morphology, crystallinity, purity, and stability using various techniques such as X-ray diffraction (XRD), infrared spectroscopy (IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), and BET surface area analysis. These techniques revealed that the sol-gel derived samples exhibited spinel ferrite phases of higher crystallinity and purity than the co-precipitation derived CuFe<sub>2</sub>O<sub>4</sub> samples. Both methods demonstrated CuFe<sub>2</sub>O<sub>4</sub> thermal stability up to about 750 °C as confirmed by TGA measurements. The IR spectra showed the vibrational mode around 600 cm-1 which emphasizes the presence of the ferrite phase. The SEM images indicated that the “asprepared” CuFe<sub>2</sub>O<sub>4</sub> powders exhibited a porous sponge-like morphology which changed significantly upon calcination at 500 °C and 750 °C.
