  4. Abstract:
  5. The aim of the present study was to evaluate the photocatalytic degradation of anthracene using Fe-doped TiO2 nanoparticles in the presence of UV. The structure and morphology of Fe-doped TiO2 nanoparticles were studied by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. The applied nanoparticles were synthesized by the sol–gel method. The effect of influential parameters on the degradation of anthracene, including pH, time, nanopar-ticles dosage, and the concentration of anthracene was studied. Using the UV/Fe-doped TiO2 system, the optimum experimental values were obtained to be as follows: pH = 7, contact time = 60 min, anthracene concentration = 5 mg/L, and nanoparticle dosage = 100 mg/L. Based on the results, it could be concluded that the photocatalytic degradation of anthracene using the UV/Fe-doped TiO2 provides suitable efficiency. In addition, it was found that the doped TiO2 could be considered as a proper catalyst in photocatalytic degradation processes. © 2021 Desalination Publications. All rights reserved
