TiO2及其TiO2／ZnO复合材料降低印染废水COD的研究

摘要

文章主要探讨了TiO2及其TiO2／ZnO复合材料光催化氧化在处理印染废水中的应用。通过两组实验考察了TiO2及其TiO2／ZnO复合光催化剂在紫外光照射下对印染废水水中COD的去除率。结果得出，复合材料作为光催化剂在较短波长下氧化还原性物质的效果最佳。%The paper probe into TiO2 and TiO2/ZnO composite catalyze law of oxidizing in river application punish , only mainly. Investigate TiO2 and TiO2/ZnO compound all catalyst until ultraviolet ray shine to river removal rate of the pollutant through two group experiment, Results obtained, The best of composite materials as catalyze and oxidize reducing substances in a relatively short wavelength.
