文摘

•: Pd-flyash and Pd-Fe₃O₄-flyash activate H₂O₂ for decolorizing aqueous solutions.
•: Basic and industrial azo reactive dyes are removed by this technique.
•: Magnetic separation of Pd-Fe₃O₄-flyash catalyst is achieved.
•: Activated carbon reduces significantly the final COD level via adsorption.
•: Technology bridges the gap between thermal power plants and dye-related industries.
