| 摘 要： | 采用溶胶-凝胶法制备CdS/TiO2复合型光催化剂,并以溴氨酸为降解对象,在太阳光下研究其降解性能,从色度、COD、TOC等不同角度对降解结果进行检测.结果表明：在太阳光下CdS/TiO2能够有效降解溴氨酸废水,CdS/TiO2的最佳比例为0.2∶1;反应中催化剂的最佳用量为2.0 g/L;溴氨酸光催化降解遵循表观一级动力学反应.在对某实际染料废水的降解中,色度和COD的最大去除率分别为94.71%和58.02%.

| Abstract: | Compound photocatalyst CdS/TiO2 was prepared by sol-gel method and applied to the degradation of bro-manine acid.The degradation experiments were performed under sunlight and the results were evaluated by the pa-rameters of chroma,COD and TOC.The research result indicated that the bromanine acid wastewater could be de-graded effectively by CdS/TiO2 under sunlight.The optimal ratio of CdS/TiO2 was 0.2∶1 under sunlight and the op-timal quantity of photocatalyst was 2.0 g/L.The photodegradation of bromanine acid followed apparent first-order kinetics.In the real degradation of dye waste water,the maximal removal ratio of COD and chroma were 94.71% and 58.02% respectively. |
