J. Catal. VL - 5 IS - 1 SE - DO - 10.11113/mjcat.v5n1.159 UR - https://mjcat.utm.my/index.php/MalJCat/article/view/159 SP - AB - <p>In the present study, a bimetallic oxide catalyst of CuFe<sub>2</sub>O<sub>4</sub> was synthesized via facile co-precipitation process and characterized using various techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscope (FESEM), energy dispersive X-ray (EDX), N<sub>2</sub> adsorption – desorption analysis and UV-visible spectroscopy. Subsequently, it was used to degrade ciprofloxacin, a fluoroquinolone antibiotic, from an aqueous solution under various conditions. The effect of various operational parameters such as catalyst loading, H<sub>2</sub>O<sub>2</sub> volume, initial ciprofloxacin concentration, inorganic ions, and solar irradiation has also been evaluated. The removal process was found to follow the trend: photo-Fenton &gt; Fenton &gt; catalytic &gt; adsorption &gt; photolysis. Finally, the results showed that CuFe<sub>2</sub>O<sub>4</sub> catalyst degraded a high percentage of ciprofloxacin and maintained reasonable efficiency even after five cycles. Thus, CuFe<sub>2</sub>O<sub>4</sub> is a promising catalyst for the activation of H<sub>2</sub>O<sub>2</sub> to degrade ciprofloxacin antibiotics.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p> ER -
