| 中文摘要 |
| 以不同波长紫外光为光源 ,研究了活性艳红在间歇式反应器中的光降解、光催化降解、光电协同催化降解行为 .结果表明 :在相同条件下 ,光催化降解速度快于光降解速度 ,而光电协同催化降解速度取决于协同电场的方向 ,当电场方向与紫外线照射方向相同时 ,降解速度比光催化速度慢 ,而当电场方向与紫外线照射方向相反时 ,其降解速度快于光催化降解速率 . |
| 英文摘要 |
| Using 365nm and 254nm UV lamp as light source,the degradation of dye X-3B in photolysis,photocatalysis and electrical enhanced photocatalysis was studied in this research.The result shows that the degradation rate of photocatalysis of X-3B was faster than one of photolysis of X-3B.The degradation rate of electrical enhanced photocatalysis was faster than the photocatalysis while the direction of the electric field was opposite with the direction of UV radiation and its degradation rate was slower while the direction of the electric field was of the same direction as UV radiation. |
