| 中文摘要 |
| 反应体系20mg/L 4-氯酚在光照条件下,C-Cl键断裂,用离子色谱检测了Cl-浓度。在模拟太阳光照射下,Al3+加速C-Cl键断裂的作用较明显；在紫外光照射下,氯原子迅速从4-氯酚分子中苯环上断裂,Al3+、Fe2+、Fe3+对该过程的影响很小。最后用Cl-浓度变化研究了反应体系的动力学性质。 |
| 英文摘要 |
| Under shining of light,C—Cl bond is broken off in the reaction system of 20mg/L 4-chlorophenol,Cl- ion can be determined quantitatively by IC.Under simulated sunlight,the effect of Al3+ that accelerated the breakage of C—Cl bond is more striking.Under UV,Cl atom is broken off from benzene ring in 4-chlorophenol molecule rapidly and Al3+,Fe2+,Fe3+ have very little effect on this process.At last,the kinetics of dechlorination was studied by Cl- ion concentration. |
