Degradation of antibiotic chloramphenicol in water by pulsed discharge plasma combined with TiO 2/WO 3 composites: mechanism and degradation pathway. JOURNAL OF HAZARDOUS MATERIALS 2019; 371:666-676. [PMID: 30889463 DOI: 10.1016/j.jhazmat.2019.03.051] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/24/2018] [Revised: 03/04/2019] [Accepted: 03/11/2019] [Indexed: 06/09/2023]
Abstract
Pulsed discharge plasma (PDP) combined with TiO2/WO3 composites for chloramphenicol (CAP) degradation was investigated. The prepared TiO2/WO3 composites were characterized by scanning electron microscope, transmission electron microscope, nitrogen adsorption apparatus, zeta sizer, X-ray diffraction, Raman spectra, UV-Vis absorption spectroscopy, X-ray photoelectron spectroscopy, photocurrent and electrochemical impedance spectroscopy. The degradation performance showed that the addition of TiO2/WO3 composites significantly enhanced the removal efficiency of CAP in PDP system. At a peak voltage of 18 kV, the highest removal efficiency of CAP could reach 88.1% in PDP system with 4 wt% TiO2/WO3, which was 36.8% and 26.0% higher than that in sole PDP system and PDP/TiO2 system, respectively. The TiO2/WO3 composites significantly accelerated interfacial charge transfer process compared to the pure TiO2. Besides, the effect of catalyst dosage and peak voltage on CAP removal was evaluated. OH, O3O2-, h+ and high-energy electrons contributed to CAP degradation in PDP-TiO2/WO3 system. Addition of TiO2/WO3 composites can decompose O3 and produce more OH and H2O2. The degradation intermediates were measured by liquid chromatography-mass spectrometry (LC-MS) and ion chromatography (IC). The cycling degradation experiment showed that the TiO2/WO3 composites have good reusability as well as stability.
