去除难降解有机废水COD用高效多相催化剂的研究

Highly Efficient Heterogeneous Catalystfor COD Removal of Poor-degradable Wasterwater

以超细 γ- Al2 O3 为载体 ,担载 Cu O,制备去除有机废水 COD用高效超细 γ- Al2 O3 /Cu O催化剂 ,采用 TEM和XRD对粒子形态进行表征 .以水溶性偶氮染料活性艳红 X- 3 B为处理对象 ,采用不同载体制备催化剂 ,考察其催化效率 ,结果表明超细 γ- Al2 O3 /Cu O催化剂的效率最高 .

The highly efficient heterogeneous catalyst prepared by supporting Cu O on ultrafineγ- Al2 O3particles was characterized by TEM and XRD. The catalysts prepared with different carriers were employed for catalytic degradation of azo dye active red X- 3B in aerated solution. The results show thatthe activity ofultrafineγ- Al2 O3/ Cu O ishigherthan those of thecatalystson other carriers.
