dcterms.abstract | Reactive oxygen species (ROS) production for Fe0 is limited because of the formed iron corrosion products. In this study, C/Fe3C/Fe0 composite which produces enhanced ROS has been specifically designed and fabricated to remove typical antibiotics (i.e., oxytetracycline (OTC) and chloramphenicol (CAP)) as a heterogeneous Fenton-like catalyst. The C/Fe3C/Fe0 composite demonstrated excellent performance for both OTC and CAP removal as compared with Fe0 and biochar. Furthermore, X-ray photoelectron spectrometry, Fourier transform infrared spectrometry, high performance liquid chromatography-mass spectra and electron spin resonance analyses were conducted to elucidate the adsorption and degradation mechanisms. The adsorption of OTC and CAP was mainly dominated by H bonds and the electron-acceptor-acceptor on the surface of the C/Fe3C/Fe0 composite, respectively. In particular, [rad]OH simultaneously induced the degradation of OTC and CAP, while 1O2 presented the selective oxidation to OTC. More specifically, the degradation of OTC over C/Fe3C/Fe0 was stronger and faster than that of CAP, leading to 65.84% and 16.84% of removal efficiency for OTC and CAP, respectively. Furthermore, C/Fe3C/Fe0 exhibited superior reusability and stability after regeneration, but regenerated Fe0 almost lost its reactivity. Therefore, the efficiency in situ generation of 1O2 using C/Fe3C/Fe0 would shed new light on the selective oxidation of aqueous organic compounds. | - |
