In the present work, sol-gel and co-precipitation techniques were used for synthesis of Fe-TiO2@Fe3O4 nanoparticles (NPs) Fe3O4, respectively. These photocatalytic removal amoxicillin. characteristics analyzed via Energy Dispersive X-ray Spectroscopy) EDX(, field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy) FT-IR(, Vibrating Sample Magnetometer) VSM(, diffraction) XRD(, Brunauer Emmett Teller (BET), Diffuse reflectance spectroscopy (DRS). The effect different parameters, like pH (11-3), number NPs (100–200 mg), amoxicillin primary concentration (40–80 mg/L), on elimination by OFAT method (one factor at a time) diverse times (0–75 min), was studied. mean size Fe-TiO2 Fe3O4 is 15.05 18.12 nm, incorporation iron into titanium dioxide acts as an intermediate energy level, reducing band gap shifting light absorption to visible range. Chemical bonding stretching vibrations related hydroxyl group (structural water OH group) observed in FT-IR results. optimum results maximum effectiveness reaction rate constant achieved 7. weight 600 mg 40 mg/L 75 min time. decreased from 99.9% 89% after five recycling steps.
