활성탄에 의한 Trihalomethane의 흡착
Adsorption of Trihalomethane on Activated Carbon
음용수를 염소 소독 처리함으로서 생겨나는 Trihalomethan(THM)을 제거하기 위한 방법으로 활성탄에 의한 흡착을 다루었다. 단일 성분의 흡착 평형은 Freundlich식으로 나타내었으며, 2성분 평형량은 이상 흡착 용액이론(ideal adsorbed solution theory)으로 계산하였다. 입자 내부에서의 확산 계수는 회분식 실험을 통하여 구하였다. 고정층 흡착 장치에서 THM의 흡착 거동은 표면 확산 기구에 기초를 둔 LDFA(linear driving force approximation)를 이용하여 만족스럽게 모사되었다.
Adsorption of Trihalomethanes(THM) on activated carbon was studied as a removal technique for THM formed during the chlorination process of drinking water. Adsorption equilibrium data of single species were represented by Freundlich equation and binary adsorption equilibria were calculated by the ideal adsorbed solution theory(IAST). Intraparticle diffusion coefficients were obtained from batch experiments. The adsorption behavior of THM in a fixed bed adsorber was satisfactorily simulated by the linear driving force approximation(LDFA) based on surface diffusion mechanism.
