本文以活性炭负载二氧化钛为光催化剂，在紫外灯照射下对分散染料溶液进行光催化降解实验研究。通过改变光催化剂用量、溶液pH、溶液的初始浓度，探讨了光催化降解两种分散染料的规律，进一步运用Langmuir—Hinshelwood力学方程对两种染料降解动力学规律进行了研究。结果表明，分散深蓝溶液浓度在2．5mg／L，分散翠蓝溶液浓度在8mg／L时，染料适宜pH值均为4，催化剂投入量为1g／L，此时降解效果最好，二者的光催化反应均符合一级动力学规律。

Photocatalytic degradation of two--type dyestuffs waste water （S--3BG and S--GL）have been investigated using titanium dioxide supported on active carbon, with various factors, just like dosage of photocatalyst, pH value of the solution, initial concentration of dye solution. From the experimental results of photocatalytic degradation of S--3BG and S--GL, the conclusions can be attained that, the S--3BG concentration at 2. 5 mg/L or S--GL concentration at 8mg/L, pH value being 4, the photoeatalyst dosage at 1 g/L, the photoeatalytic degradation effieiencies were approximated to the maximum values, further, the photocatalyses of them were the apparent first--order kinetic reaction.
