Antibiotics have been used for the treatment of microbial infections over several decades for both human and animals. However, these antibiotics are classified as potent pollutants due to their increasing overuse. Amoxicillin is one of the most frequently used antibiotics and its bioaccumulation in the food chain can threaten the human health. Herein, we show the adsorption activity of amoxicillin from aqueous solution using graphene oxide/calcium alginate composite, which is easy to operate, low-cost material. The composite has been characterized by UV-Vis spectroscopy, IR, SEM. The adsorption properties of amoxicillin were investigated through several parameters including the solution pH, the absorbent does, the initial concentration. Finally, a mechanism of adsorption has been proposed in this study.
