Magnetic Activated-ATP@Fe₃O₄ Nanocomposite as an Efficient Fenton-Like Heterogeneous Catalyst for Degradation of Ethidium Bromide.

ABSTRACT: Magnetic attapulgite-Fe₃O₄ nanocomposites (ATP-Fe₃O₄) were prepared by coprecipitation of Fe₃O₄ on ATP. The composites were characterized by scanning electron microscopey, X-ray diffractometry, Brunauer-Emmett-Teller analysis, X-ray photoelectron spectroscopy, energy dispersive spectrometer and transmission electron microscopy. Surface characterization showed that Fe₃O₄ particles with an average size of approximately 15 nm were successfully embedded in matrix of ATP. The capacity of the Fe₃O₄-activated ATP (A-ATP@Fe₃O₄) composites for catalytic degradation of ethidium bromide (EtBr, 80 mg/L) at different pH values, hydrogen peroxide (H₂O₂
