영문 초록

Photocatalytic reaction using TiO₂thin film was applied for the inactivation of coliform bacteria and the degradation of formic acid. UV processes coupled with and without TiO₂were tested for the river water samples. It took 5 and 15 minutes, respectively, to obtain 99% destruction of coliform bacteria in the total coliform test, which demonstrated the effectiveness of the photocatalytic reaction. Complete degradation of formic acid determined by TOC analysis was observed in 20 minutes by ozone/photocatalysis, while formic acid was degraded as little as about 20% during the first 100 minutes by ozone treatment alone. When ozone was supplied to the TiO₂/UV system, however, it provided a synnergetic effect for the degradation of formic acid.
