Abstract

Background: Among water pollutants, Natural Organic Matters (NOMs) are highly important for making problems in water treatment plants. Objectives: The main objective of this study was to investigate the efficiency of photocatalytic degradation of Humic Acid using Magnetic Nanoparticles (Fe-doped TiO2@Fe3O4) in aqueous solutions. Methods: In the present experiment, Fe-doped TiO2@Fe3O4 nanoparticles were synthesized by the sol-gel method, and SEM, XRD, and DRS analyzes were utilized to characterize the synthesized nanoparticles. The effects of various variables, including pH (3-11), initial concentration of Humic Acid (20-80 mg/L), and concentration of nanoparticles (250-2000 mg/L) at different reaction times (15-60 min) were investigated on the photocatalytic degradation of Humic Acid. Results: The maximum degradation efficiency of Humic Acid at pH 3, the initial Humic Acid concentration of 5 mg/L, nanoparticle dose of 400 mg/L, and reaction time of 60 min using a 15-W bare UV lamp. Conclusions: Due to the high efficiency of photocatalytic degradation, it is proposed to use for the removal of Humic Acid from water resources.
