摘要
探讨了在光 Fenton体系中引入催化剂TiO2 对几种氯代有机物的光氧化降解效果及其影响因素。试验结果表明 ,TiO2 Fenton试剂复合体系对CH2 ClCOOH的光解脱氯速率显著高于TiO2 和Fenton试剂体系 ,TiO2 对Fenton光氧化反应有较强的催化作用 ;溶液 pH值、铁离子浓度。
The effect and some influence factors on photodegradation of chlorinated organic compounds by TiO 2 fenton systems were studied. UV/Fenton TiO 2 systems prove to be most effective for dechlorination of CH 2ClCOOH than only TiO 2 photocatalyst or photo Fenton reaction. The obviously catalytic effect of TiO 2 on photo Fenton reaction was observed. The factors such as pH of solution, constraction of Fe 3+ , compose and structure of chlorinated organic compounds obviously influence on photodegradation of these organic compounds by UV/Fenton TiO 2 systems.
