| Abstract: | 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. |
