The first part of the study explored the adsorption of chlorobiphenyls onto glass. Langmuir-first order reaction was used in the adsorption and the photocatalytic oxidation. The results showed some were false in photocatalytic oxidation reaction usingthe Langmuir-first order reaction. In the second half of this study, the photocatalytic oxidation (photo- Fenton and UV/TiO2 processes) of chlorobiphenyls was investigated. With respect to the simulated the photo-Fenton experimental data, the relationship between the reaction rate for chlorobiphenyls and H2O2 concentration was expressed as zero or firstorder reaction and that between the reaction rate and the Fe(II) concentration was a saturation-type reaction. The degradation of TOC was shown for the stronger oxidative ability of the photo-Fenton process more than UV/TiO2. |
