Highly Efficient Adsorption and Removal of Amoxicillin from Aqueous Solution by Magnetic Graphene Oxide Nanocomposite

Background: Antibiotics have lasting effects on the environment. Among properties of these substances are non-biodegradable, carcinogenic, high toxicity, and an increase in antibiotic-resistant bacteria. Therefore, they should be removed from aqueous solutions point this think was to adsorb amoxicillin (AMO) by magnetic graphene oxide nanocomposite (MGO). Methods: The adsorption behavior AMO studied a series batch experiments as function pH (3-11), contact time (0-120 min), concentration (10-100 mg/L) different MGO dosages (0.1-1 g/L). structures were confirmed scanning electron microscope (SEM), X-ray diffraction (XRD). Results: results revealed optimized conditions (pH=3, time=75 min, concentration= 10mg/L adsorbent dose=0.75 g/L) maximum capacity removal efficiency 98.41 mg/g, respectively. thermodynamical parameters showed that sorption method endothermal spontaneous. Conclusion: nanoparticles extended capabilities such easy rapid separation solution potential removing AMO, so, it can introduced appropriate for antibiotics water wastewater.
