Study on Treatment of Basic Yellow 28 dye Wastewater by Micro-nano Bubble Ozone Catalytic Oxidation

Mn loaded AC (Mn/AC), Cu (Cu/AC), and Fe (Fe/AC) catalysts were prepared by the impregnation-calcination method, which can be used to degrade Basic Yellow 28 dyes in simulated printing dyeing wastewater for catalytic ozonation. The catalyst preparation reaction conditions optimized with degradation efficiency of chemical oxygen demand (COD) absorbance some organic compounds under 254 nm UV light (UV254) as indicators. surface structure, specific area, active component distribution analyzed scanning electron microscopy (SEM), nitrogen adsorption, X-ray diffraction (XRD) characterization. Results indicated that was best component, a dosage 3.5 g/L, an initial pH 9.4, temperature 31.7°C parameters dyes. After five recycling experiments, could retain relatively stable effect. Furthermore, this study informative sustainable development future catalysts.
