Abstract

We evaluated the treatment efficiency of humic acid using Ti and anodized TiO2metal plate with/without Fe-doping. Variation of humic acid concentration after 60 minutes of UV irradiation in the case of Ti only, Fe-Ti, TiO2only and Fe-TiO2was about 3.0%, 5.5%, 9.8% and 9.2%, respectively. . It is found that hypochromic effect was revealed in all cases with respect to doping time. Fe doping method is considered to be effective for humic acid degradation in spite of relatively low surface area of Ti and anodized TiO2metal plate.
