Adsorptive Removal of Oxytetracycline Antibiotic from Graphene Oxide Nanocomposite Modified with Magnesium Oxide and Methyl Methacrylate

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 ۰.۰۱۵ g, ۶۰ min contact time, pH ۸, and over ۹۰% 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 ۱۳۱.۳۳ mg/g. The regenerated adsorbent showed high capacity, making it a cost-effective solution.
