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。
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 theCuO-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 and catalyst, as well as the increase of initial concontration of X-3B wastewater. Acidic condition can promote the degra- dation of X-3B wastewater. Compared with direct dyestuff, the degradation of reactive dyestuff wastewater by CuO-H2O2 system is more efficient.
