초록

본 연구에서는 광촉매 산화반응을 이용한 반응성염료(Reactive Black 5)의 오염부하 저감율(TOC, 색도제거율)을 조사하였다. 광촉매 반응활성의 주요한 인자로서 염료농도, TiO2 주입량 및 pH 조건을 최적화하였으며, 실험에 적용된 최적의 조건은 각각 100 mg/L, 2 g/L, pH 4.9였다. 용존산소의 경우에는 산소의 농도가 증가함에 따라 처리속도도 함께 증가하였다. 새로운 TiO2를 적용한 경우와 MF 세라믹 분리막에 의해 재생된 TiO2를 각각 적용하여 실험한 결과 색도제거율과 처리속도에는 약간의 차이를 보였으나, 반응 전반에는 영향을 주지 않았다.

We investigated the reduction of pollutants such as TOC (total organic carbon) and decolorization of Reactive Black 5 (RB5) by photocatalytic oxidation. The optimal values of major parameters for the reaction were obtained including the concentration of RB5, the amount of TiO2 dosage and pH of solution. The values were 100 mg/L, 2 g/L and 4.9, respectively. As the concentration of oxygen increased, removal rate of pollutants increased. After TiO2 was regenerated and used again by micro filtration (MF) ceramic membrane, the removal efficiency of color and removal rate of pollutants did not decrease significantly.
