摘要
本文研究了使用半导体光催化法处理可溶性染料水溶液的降解情况。以直接耐酸大红4BS、酸性红G为例进行了试验。实验表明,在浓度约为10ppm的水溶液中,当高压汞灯照射20~30分钟后,两染料都已脱色,并伴随染料分子中的芳环断裂。
In this paper, the semi-conductor photodegradation method for soluble dyes is discussed. The dyes (acid red G and direct red 4BS), in dilute (10 ppm) aqueous solutions, are treated with heterogeneous photoassisted catalysis (by using near-uv-illuminated TiO)_2. Experiments show that this method is effective in color removal from dye-solutions and the breakdown of the aromatic ring.
