| 摘 要： | 光催化氧化法降解水中有机污染物是近来发展较为迅速的废水处理技术，以锐钛型载银TiO2为催化剂，在发射光谱波长为254nm，功率的15W紫外灯照射下，考察不同H2O2浓度对Aroclor1260的光催化降解的影响，结果表明：低浓度的H2O2对Aroclor1260的光催化降解有促进作用，而当H2O2的浓度高于30mol/l时，光催化降解受到抑制，而且这种影响对不同PCB单体化合物的效果基本一致。

| Abstract: | Photocatalytic oxidation of organic pollutant has accepted repid development in wastewater treatment.The effects of different concentrations of H 2O 2 on the photocatalytic degradation (PD as abbreviation) of Aroclor 1260 were investigated with Ag loaded anatase form TiO 2 as catalyst and 15W UV lamp as light source.The results showed that H 2O 2 with lower concentrations could improve the PD rate,and the PD rate was contrarily hindered with H 2O 2 concentrations higher than 30 mol/l.What is more,the effects aforementioned were very similar for different PCBs congeners. |
