| ABSTRACT |
|
This study evaluated the photocatalytic oxidation of BPA using the RPOD reactor under various conditions. This study found that the RPOD was
effective for BPA degradation. It could reduce 1 mg/L of BPA by half within 5 min under the optimum conditions. According to the study results,
TiO2 coating was important for the BPA oxidation. As the coating thickness increased, the removal efficiency improved. The light source, the light
intensity and the drum rotating speed were important for the oxidation. The UV light was more effective for the BPA degradation than the visible
light. The removal efficiency improved with increasing intensity. As the drum speed increased, the removal efficiency improved. The maximum
speed was 240 rpm in this study. Addition of air and nitrogen was not beneficial for the BPA degradation in this study probably due to enough
oxygen in the water. |
