COMPARISON BETWEEN FE3O4 AND FE3O3 NANOPARTICLES FOR REMOVAL OF AMOXICILLIN FROM WASTEWATER USING PHOTO-FENTON PROCESS

Water-related problems are likely to increase dramatically due to climatic changes and the increase in population growth. Therefore, the need to application performance, ecofriendly methods are to treat and remove pollutants with chemical composition and complex structure that are difficult to decompose in water, such as antibiotics. In this study, amoxicillin (AMX) was removed from wastewater using nanoparticles (NPs) made of UV/H2O2/ Fe3O4 and Fe2O3. In batch studies, several operating conditions were utilized, including different doses of (25, 50, 75, 100, and 125 mg/l), pH (3, 5, 7, 9), Fe3O4Fe3O4 (NPs), and Fe2O3 Fe2O3 (g/l), correspondingly. Three Ultra violet (UV) lamps were used and the detention time was kept constant (120 min). The best efficiency obtained under these conditions when using 10 mg/l of AMX, 5 mg/l of Fe3O4 nanoparticles, pH=3, and H2O2= 25 mg/l was 99.5%; while, the best efficiency obtained for Fe2O3Fe2O3 nanoparticles at AMX =10 mg/l, pH=3, H2O2H2O2 = 50 mg/l, and 10 mg/l of Fe2O3Fe2O3 was 97.3%. After Comparing the two NPs, it was found that Fe3O4Fe3O4 was the best in the removal of AMX concentration (10 mg/l) with 99.5% efficiency within two hours by using Fe3O4 = Fe3O4= 5 mg/l, pH=3, and H2O2H2O2 = 25 mg/l. While, Fe2O3Fe2O3 nanoparticles were the best in removing AMX concentration (25 mg/l) with 97.7% efficiency by adding 50 mg/l of H2O2H2O2 and 10 mg/l of Fe2O3Fe2O3 in neutral condition within two hours
