摘要
研究了纳米ＴｉＯ２光催化剂对活性黄Ｘ６Ｇ、活性红Ｘ３Ｂ、活性蓝ＸＢＲ、碱性绿、碱性紫５ＢＮ、碱性品红等６种染料溶液的光解脱色效果。结果表明，在ｐＨ２的酸性溶液中，对浓度为６０ｍｇ／Ｌ的６种染料溶液的脱色率均超过９３．３％；即使对浓度达２００ｍｇ／Ｌ的活性蓝溶液，其脱色率仍可达７８．８％。
The photodegradation decoloring
efficiencies of Nanometer TiO 2 (a kind of photocatalyst) to dyeing wastewater containing water
soluble dyes (Reactive Yellow X6G, Reactive Red X3B, Reactive Blue XBR, Alkali Green, Alkali
Violet and Alkali Fuchsin) have been studied. The results of the study showed that in pH 2 acidic
medium the decoloring efficiencies of Nanometer TiO 2 to the six dyestuff solutions (60 mg/L)
were all exceeding 93.3%. Even to the high concentration Reactive Blue solution (200 mg/L) the
decoloring rate could still be as high as 78.8%. It was also concluded that the pH value of
dyestuff solution has a significant influence to the decoloring function of Nanometer TiO 2.
