Treatment of gas-phase trichloroethene by UV/O{sub 3} process
- National Taiwan Inst. of Technology, Taipei (Taiwan, Province of China)
The reaction behaviors of the photolysis of gas-phase trichloroethene (TCE) in presence of ozone was studied. The distributions and temporal behaviors of TCE and chlorinated intermediates were studied and described in terms of a two-step consecutive dechlorination kinetic model. The decomposition of TCE (324 ppmv) was found to be completed (99%) within 22 seconds and the rate was increased with increasing light intensity. Supplementary ozone would have more contribution to the dechlorination of chlorinated intermediates than that of TCE by the UV/O{sub 3} process. The enhancement of UV light intensity would promote the dechlorination of TCE more effectively than the supplement of ozone. 8 refs., 6 figs.
