摘要
本文考察了3种卤素离子对TiO2/沸石以及P25光催化降解酸性桃红的影响,实验结果表明:加入卤素离子F-、Cl-和I-均减慢了酸性桃红光脱色反应的速率,并且COD去除率也逐渐降低;加入卤素离子对TiO2/沸石催化剂脱色反应速率的影响较P25小,而且TiO2/沸石催化剂更加易于从分散体系中分离出来,说明它是一个有应用前途的催化剂。另外,进行了H2O2测定和DMPO自旋捕获自由基的ESR光谱测定。
The effect of three halogen ions on the photodegradation of SRB on TiO2/zeolite and P25 was investigated. The experimental results showed that the addition of F-,Cl- and I- decreased the decol- ored rate of SRB and the rate of COD change of SRB. The effect halogen ions on the photodegradation of SRB on TiO2/zeolite was smaller than that on P25. TiO2/zeolite was easier to be separated from aqueous suspensions. This phenomenon showed that TiO2/zeolite was an applicable catalyst. The detections of H2O2 and electron paramagnetic resonance （EPR） spectra were made.
