عنوان انگلیسی Adsorptive Removal of Oxytetracycline Antibiotic from Graphene Oxide Nanocomposite Modified with Magnesium Oxide and Methyl Methacrylate
چکیده انگلیسی مقاله Antibiotics revolutionized medicine, but misuse leads to antimicrobial resistance, posing threats to their usefulness and increasing disease spread and death risk. Discovering new microbial natural products is crucial to address this issue. The study investigates the effectiveness of a graphene oxide nanocomposite coated with magnesium oxide and methyl methacrylate in removing oxytetracycline from water. The study found optimal efficiency for adsorption with 0.015 g, 60 min contact time, pH 8, and over 90% removal rate. The Langmuir model best fits the data, with a pseudo-second-order kinetic model. Temperature also decreased adsorption efficiency. The Langmuir model was best fitted to the experimental data, indicating a maximum adsorption capacity of 131.33 mg/g. The regenerated adsorbent showed high capacity, making it a cost-effective solution.
