Abstract
본 연구에서는 활성탄을 흡착제로 사용하여 아세트산의 흡착 평형 실험을 313.15, 323.15 K에서 수행하였다. 아세트산의 흡착평형 데이터를 Langmuir, Bi-Langmuir, Freundlich model로부터의 계산 결과와 비교하였다. 이 과정에서각 model 내 isotherm parameter는 실험값과 계산값의 차이의 제곱의 합을 최소화하는 방식으로 결정하였다. 비교 결과활성탄상에서의 아세트산의 흡착평형 데이터를 가장 잘 설명해주는 model은 Bi-Langmuir model이었음을 확인하였다. In this study, the adsorption equilibria of acetic acid on activated carbon were investigated at the temperatures of 313.15 K and 323.15 K. The obtained adsorption data were then fitted by Langmuir, Bi-Langmuir, and Freundlich models, in which the relevant model parameters were determined by minimizing the sum of the squares of deviations between experimental data and calculated values. The comparison results revealed that Bi-Langmuir model could account for the adsorption equilibrium data of acetic acid with the highest accuracy among the three adsorption models considered.
