The adsorption of 2,4,6-trichlorophenol (TCP) by activated carbon was carried out at 30 ¡ãC with initial concentrations of 100-600 mg/L. The adsorption capacity of TCP was 457.9 mg/g at 30 ¡ãC. The adsorption isotherm and kinetics of TCP by activated carbon are investigated. The equilibrium isotherms of TCP/acetone mixtures were determined using a conventional method. Pseudo-Ideal adsorption model was used to analyze the liquid phase adsorption equilibrium data of TCP. As a result, the adsorption isotherm followed the Langmuir class (L type) and fits the experimental data well. The adsorption isotherm constant in this work also was compared with other researcher¡¯s work showing the comparable values.
