Abstract:

Reactive brilliant red X-3B has been selected as a model pollution substrate. Various influencing factors and reaction mechanism of catalytic oxidation dyestuff wastewater by the CuO-H₂O₂ system under low temperature and normal atmosphere conditions are studied. The results show that reactive brilliant red X-3B can be oxidized completely and effectively by the CuO-H₂O₂ system. Its oxidation rate can be as high as 99%. The speed of dyestuff wastewater degradation by CuO-H₂O₂ system increases with the increase of temperature，and dosages of oxidant andcatalyst，as well as the increase of initial concontration of X-3B wastewater. Acidic condition can promote the degradation of X-3B wastewater. Compared with direct dyestuff，the degradation of reactive dyestuff wastewater by CuOH₂O₂ system is more efficient.

Key words: CuO-H₂O₂, reactive brilliant red X-3B, catalytic oxidation

摘要：

以活性艳红X-3B为模拟底物,研究了低温常压条件下CuO-H₂O₂体系催化氧化染料废水的各种影响因素及反应机制。结果表明,CuO-H₂O₂体系能高效彻底地氧化活性艳红X-3B,氧化率可高达99%。CuO-H₂O₂体系降解染料废水的速率随温度、氧化剂和催化剂投加量以及X-3B废水初始浓度的升高而升高。酸性条件能促进X-3B废水的降解。与直接染料相比,CuO-H₂O₂体系降解活性染料废水更加有效。
