| Summary: | 碩士 === 國立台灣工業技術學院 === 化學工程技術研究所 === 85 === The purpose of this research is to investigate the effect of
ferrous, copper, bromide and nitrate ions and t-butanol on the
decompositionof 2-chlorophenolby Ozone and UV/Oozone processes
in aqueoussolution. The experiments were carried out under
various pH valuesto investigate the efficiencies of
decomposition, dechlorination and mineralization of
2-chlorophenol by Ozone and UV/Ozone processes.The addition of
ions had slight influence on the decomposition of 2-chlorophenol
by Ozone and UV/Ozone processes. By adding ferrousions would
promote the mineralization of organic by UV/O3 processesunder
acidic conditions. Organic intermediates were not
mineralizedcompletely by Oozne and UV/Ozone processes in
alkaline solutions.The kinetic models were found to fit well in
modeling the temporal behaviors of reacting species on the
decomposition of 2-chlorophenolby O3 and UV/O3 processes. The
addition of t-butanol altered the surfacetension of aqueous
solutions and promote the decomposition of 2-chlorophenol in
both Ozone and UV/Ozone processes, but it couldinhibit the
dechlorination under the situation of chemical controlled
region.
