다국어 초록 (Multilingual Abstract)

Photocatalytic removal of bisphenol-A with a rotating photocatalytic oxidation drum(RPODrum) reactor has been investigated in various conditions. It has been found that TiO₂ thin film thickness of 455 ㎚ is more effective than 285 ㎚ in the photocatalytic activity. A germicidal lamp as a light source was more effective than a blacklight lamp. In addition, the germicidal lamp with the light intensity of 6 W/L has increased the removal efficiency by 13% compared to that with 4 W/ L lamp. 1fie blowing of air and N₂ gas at the flow of 0.5 L/min has not further increased the removal efficiency of bisphenol-A. To reduce the retention time of solution, higher rotation speed of RPO drum was needed and the most efficient rotating-speed was 240 rpm. The reaction rate constant k, and the half-life tin in the bisphenol-A removal with the most efficiently RPO drum reactor system have been calculated to be 0.139 min^(-1) and 4.99 min, respectively.
