      Pharmaceuticals without Oxidants.

AB  - In the current study, CoFe(2)O(4) and TiO(2) nanoparticles were primarily made 
      using the sol-gel method, and subsequently, the hybrid magnetic composites of 
      TiO(2) loaded with CoFe(2)O(4) (5-15 percent w/w) were made using a hydrothermal 
      procedure. X-ray diffraction (XRD), Fourier transform infrared (FTIR) and Raman 
      spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS), 
      scanning electron microscopy (SEM), and high-resolution transmission electron 
      microscopy (HRTEM) were all used to thoroughly characterize the materials. 
      Additionally, the zero-charge point (ZCP) determination, the examination of the 
      pore structure by nitrogen adsorption, and an evaluation of magnetic properties 
      were performed. Six organic dye pollutants were selected to evaluate the 
      performance of the synthesized nanocomposites toward photocatalytic degradation, 
      including methylene blue (MB), methyl orange (MO), crystal violet (CV), acridine 
      orange (AO), rhodamine B (RhB), and rhodamine 6G (R-6G). Photodegradation of 
      tetracycline (TL), a model pharmaceutical pollutant, was also studied under UV 
      and visible light. The composites exhibited a high degradation performance in all 
      cases without using any oxidants. The photocatalytic degradation of tetracycline 
      revealed that the CoFe(2)O(4)/TiO(2) (5% w/w) composite exhibited a higher 
      photocatalytic activity than either pure TiO(2) or CoFe(2)O(4), and thus attained 
      75.31% and 50.4% degradation efficiency under UV and visible light, respectively. 
      Trapping experiments were conducted to investigate the photodegradation 
      mechanism, which revealed that holes and super oxide radicals were the most 
      active species in the photodegradation process. Finally, due to the inherent 
      magnetic attributes of the composites, their easy removal from the treated 
      solution via a simple magnet became possible.
