초록
본 연구에서는 입상활성탄에 의한 quinoline yellow의 흡착특성을 회분식 흡착과 충전층 흡착을 통해 조사하였다. Quinoline yellow에 대한 활성탄의 흡착능은 산성 pH영역과 보다 높은 흡착온도에 의해 크게 증가하였으며, 60℃, pH 3에서 초기농도(10 mg/L)의 97%를 제거할 수 있었다. 입상활성탄에 대한 quinoline yellow의 흡착평형은 25~60℃범위에서 Freundlich의 흡착등온식에 잘 맞았다. 흡착등온식으로부터 평가된 k와 β 값은 각각 38.71~166.60과 0.380~0.490이었다. 활성탄 충전층에서의 파과곡선은 초기농도, 충전층의 높이, 유입속도 등과 같은 설계변수의 영향을 받았다.
The adsorption characteristics of quinoline yellow by granular activated carbon were investigated experimently in the batch adsorber and packed column. The adsorptivity of activated carbon for quinoline yellow were largely improved by acidic pH and higher temperature. When the pH was 3 at 60℃, quinoline yellowcould be removed 97 percent of initial concentration(10 mg/L). It was estabilished that the adsorption equilibrium of quinoline yellow on granular activated carbon was successfully fitted by Freundlich isotherm equation in the temperature range from 25℃ to 60℃. The estimated values of k and β are 38.71~166.60, 0.380~0.490, respectively. The breakthrough curve of activated carbon-packed column depends on the design variables such as initial concentration, bed height, and flow rate.
