본 연구에서는 활성탄을 이용하여 수용액중의 Methylene Blue 제거 실험을 수행하였다. 등온흡착 곡선과 동력학 방정식을 구하기 위하여 Batch실험을 하였는데 실험결과 동력학 방정식은 first-order Model과 일치하였고 등온흡착곡선은 Langmuir isotherm model에 부합되었다. 동시에 일반 활성탄과 TiO2를 첨가한 활성탄의 최대 흡착량을 비교 분석하였다.
The feasibility of activated carbon to remove Methylene Blue from aqueous solutions was investigated. Batch experiments were carried out to study the isotherm and kinetics with differen initial concentration of Methylene blue. The kinetic data were fitted to first-order Model, Second-order Model and it was found to follow closely the Second-order Model model. Equilibrium data were fitted to Langmuir and Freundlich isotherm models. The equilibrium data were best represented by the Langmuir isotherm model. Also the maximum adsorption capacity was compared in the equilibrium experiment using activated carbon and TiO2-coated activated carbon.
