DOIAbstract
Emerging pollutants, among them pharmaceutical compounds, are found in surface and ground waters, suggesting their ineffective removal by conventional wastewater treatment technologies. In this paper, the removal of sodium diclofenac, a widely used non-steroidal anti-inflammatory drug, was explored by a heterogeneous Photo-Fenton process using CoFe2O4, H2O2 and Uv germicide radiation (254 nm). Cobalt ferrites, were obtained by Pechini method and calcined at 600 °C and 800 °C. They were characterized by X-ray diffraction, Uv visible spectroscopy, Mössbauer and X-ray photoelectron spectroscopy, temperature-programmed reduction and specific surface area. The inverse spinel structure was obtained, and both materials presented good performance i...
