Sumario:Nanomaterials were widely used as efficient adsorbents for environmental remediation of tetracycline pollution. However, the separation of the adsorbents posed the challenge to their practical applications. In this study, we grew magnetic MnFe(2)O(4) nanoparticles on the reduced graphene oxide (rGO) to form MnFe(2)O(4)/rGO nanocomposite with a one-step method. When used as the absorbent of Tetracycline, it exhibited an adsorption capacity of 41 mg/g. The adsorption kinetics and isotherm were fitted well with the pseudo-second order model and Freundlich model, respectively. The MnFe(2)O(4)/rGO nanocomposite could be easily extracted from the solution with the external magnetic field and regenerated with acid washing.
