【Abstract】 Activated carbon-supported Ni-Cu-K was used to treat activated red X-3B dye wastewater. The results indicated that the supported metals acted as catalysts in the oxidation reaction. To the COD and colority of activated red X-3B, the activated carbon afforded a high removal efficiency of 98.74% which is 30% higher than those without metals. The research studied the relationship between the concentration of dye wastewater and the quantity of the activated carbon.更多还原
