Abstract :

Background and Objective: Antibiotics, due to their low biodegradability, high solubility, and toxicity, threaten human health and the environment. The study aims to create the green magnetic nanocomposite MnFe2O4/BiOI and use it to clean up water solutions through a photocatalytic process when ultraviolet light is present. Material and Methodology: The study used an extract from the Calendula officinalis plant to make a green magnetic nanocomposite called MnFe2O4/BiOI. It was then tested to assess its efficiency in removing tetracycline under ultraviolet light. The characteristics of this nanocomposite were determined through XRD, VSM, TEM, FESEM, and DRS analyses. Findings: Nanocomposite MnFe2O4/BiOI has dimensions ranging from 14–45 nanometers, a band gap of 1.7 eV, and a magnetic saturation level of 19.92 emu/g. The photocatalytic process eliminated all tetracycline when the conditions were right: pH = 9, 20 mg/L of tetracycline, 0.5 g/L of MnFe2O4/BiOI nanocomposite, and 200 minutes of reaction time. Conclusion: The results of this study demonstrate that the photocatalytic process using MnFe2O4/BiOI/UV can effectively treat water contaminated with tetracycline-containing antibiotics.
