| Abstract: | Photocatalytic degradation of trichloromethane in gaseous phase has been studied by using anatase titanium dioxide powder as catalyst. The photoreactor was illuminated with a 15W (main wave length 254nm) UV lamp. The results indicated that semiconductor photocatalysis could be an effective process for degradation of gaseous trichloromethane. Air flow and light intensity did affect the degradation rate. The aqueous solution products were proved to contain chloride and hydrogen ions with approximately equal concentration. |
