| 摘 要： | 以非离子型表面活性剂－脂肪醇聚氧乙烯醚为目标污染物，投加适量光敏半导体为催化剂，在高压汞灯照射下进行实验，在探讨各种影响因素作用的基础上，提出了在弱紫外辐照下使ＡＥＯ－９降解的最佳条件组合，为逐步利用自然光源催化氧化表面活性剂提供科学依据。

| Abstract: | The typical nonionic surfactant, aliphatic alochol polyethoxylated ethers (AEO3, AEO- 9, AEO-15) are used as target pollutants. Experiments are carried out with the utilization of certain amount of photo - sensitive semi- conductor under high pressure mercury lamp.The functions of different factors are investigated and the optimal combination for the degradation of AEO- 9 under low intensity of UV light is established which provides scientific basis for the gradual transition of utilizing artificial light source to natural light source for catalytic oxidation of surfactants. |
