Abstract
The research of chlorobiphenyls in aqueous
solution was conducted in two parts. 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.
