摘　　要：以ＴｉＯ２为催化剂，采用高压紫外光和太阳光二种光源，分别对分散大红染料溶液进行光催化降解，二种光源对该溶液均有明显的降解作用，降解产物是ＣＯ２。The photocatalysis degradation of disperse red solution has been studied. The results show that titanium'dioxide was one of the most efficient catalysts in the photodegradation.With UV and Sunlight irradiation,the solution can be degradated quickly. One of the last degradation products is carbon dioxide. The effect of solution pH and titanium dioxide dosage on photodegradation of disperse red were also discussed.
