Effectiveness of fullerene/magnesium oxide nanocomposite in removing ciprofloxacin and tetracycline from aqueous solutions.

ABSTRACT: The excessive use of antibiotics, including ciprofloxacin (CIP) and tetracycline (TC), poses negative impacts on both human health and ecosystems. In this work, fullerene/magnesium oxide (F/MgO) nanocomposite was prepared and studied as adsorbent for CIP and TC removal. Adding metal oxide to F led to a change in its characteristics which was confirmed by XRD, FTIR, SEM, and TEM. A maximal removal for 50 mg L^-1 CIP was 84.6% at 60 min, pH 7, and 0.2 g L^-1 of adsorbent dose. 43.6% of 50 mg L^-1 of TC adsorbed at 60 min, pH 5, and 1 g L^-1 of adsorbent dose. Adsorption thermodynamics elucidated that the adsorption on F/MgO nanocomposite were spontaneous and exothermic, and non-spontaneous and endothermic for CIP and TC, respectively. Pseudo-second-ord
