Evaluation of FeO-MnO@RGO magnetic nanocomposite as an effective persulfate activator and metal adsorbent in aqueous solution.

A reduced graphene oxide (RGO) supported FeO-MnO nanocomposite (FeO-MnO@RGO) was successfully prepared for catalytic degradation of oxytetracycline (20 mg/L) by potassium persulfate (PS) and adsorption removal of mixture of Pb, Cu, and Cd ions (each 0.2 mM) in the synchronous scenario. The removal efficiencies of oxytetracycline, Pb, Cu, and Cd ions were observed as high as 100%, 99.
