以载Ni活性炭为催化剂 ,用空气氧化模拟染料废水活性红X 3B。实验结果表明 ,负载在活性炭上的金属离子起到催化氧化的作用。活性炭对活性红X 3B的COD和色度的去除率能达到 98 74 %以上 ,较不加金属的活性炭去除率提高 30 % ,用活性炭处理浓度为 0 4g/L的模拟废水活性红X 3B ,投加量为 5g/L时 ,催化氧化效果最明显 ,催化氧化作用对色度的去除率达 2 5 33%。

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.
