The Fe/CoFe2O4 nanocomposite was synthesized in a single step via a hydrothermal method by treating coprecipitated iron and cobalt hydroxo complexes. The obtained samples were found to have a pronounced spinel crystalline structure with the presence of metallic iron. The crystallite size was determined by various methods. The Ms value determined from the hysteresis loop was 189.24 Em/g, and Hc was 602 Oe. The physical properties of the Fe/CoFe2O4 nanocomposite were studied using an Infrared spectrophotometer (IR), scanning electron microscopy (SEM), and ultraviolet-visible (UV-visible) spectroscopy. The photocatalytic degradation of ibuprofen, streptocide, furacilin, methylene blue, tetracycline was studied using a photocatalytic nanocomposite under UV light. The effects of various parameters, such as catalyst concentration, hydrogen peroxide concentration, and treatment time, on degradation were also examined. It was confirmed that the degradation rate of pollutants follows pseudo-first-order kinetics.
