Preparation of Cu-Ce@?-Al2O3 and Study on Catalytic Ozone Oxidation for the Treatment of RO Concentrate Water

In this paper, a high-efficiency and stable Cu-Ce@?-Al2O3 catalyst was prepared by taking the reverse osmosis (RO) concentrated water of sewage treatment plant as object activated alumina carrier. The preparation factors that affected catalytic activity were investigated. SEM, EDS, XRD, BET, XRF, XPS techniques applied to characterize catalyst. Optimal working conditions, degradation mechanism RO researched. comparison with ozone oxidation alone, ozonation has more reactive groups, significantly improving effect. Characterization results show Cu Ce are successfully supported on surface support mainly exist in form oxides (e.g., CuO CeO2). loading metal led larger specific area pore volume. repeated use had an insignificant effect peaks Cu2p Ce3d energy spectra caused small loss active components. Under these removal rate COD from 85.2%. stability salt tolerance catalysts investigated wear times, respectively. organic matter residual tryptophan-like compounds observed through UV absorption spectroscopy 3D-EEM. Hydroxyl radicals participated pollutants degradation. Finally, multi-level-fuzzy analysis evaluation model developed quantitatively assess system Cu-Ce @?-Al2O3 for water.
