光催化协同臭氧降解蒽醌染料废水

Degradation of anthraquinone dye wastewater by photocatalysis combined with ozone

采用光催化协同臭氧技术降解蒽醌染料分散艳蓝E-4R,研究了光催化/臭氧法处理染料的主要影响参数,结果表明:增加臭氧的流量有利于提高脱色率,溶液初始pH值则对降解的影响较小,在光催化/臭氧体系中,对降解起到主要作用的是.OH的氧化作用。

The process of photocatalysis combined with ozone was established for degradation of an anthraquinone dye, E-4R. This paper studies major influential parameter of photocatalysis combined with ozone treatment of dye. The results showed that the color removal increased with the increasing ozone flow rate and the decreasing dye concentration, and the effect of initial pH value on color removal was relatively small. In the TiO2/UV/O3 was mainly attributed to the oxidation of OH.
