N2 - Adsorption of 2,4,6-trichlorophenol onto octyl-modified ordered mesoporous silica material from aqueous solution has been investigated systematically using batch experiments in this study. Results indicate that 2,4,6-trichlorophenol adsorption is initially rapid and the adsorption process reaches a steady state after 1 min. The adsorption isotherms are well described by the Langmuir and the Freundlich models, the former being found to provide the better fit with the experimental data. The effects of temperature and pH on the adsorption are also examined. According to the experimental results, the amount of 2,4,6-trichlorophenol adsorbed decreases with increases of temperature from 288 to 308 K, and pH from 2.0 to 11.0. Based on the results, It was found that octyl-modified ordered mesoporous silica shows significant adsorption for 2,4,6-trichlorophenol. This might be due to hydrophobic interaction among the octyl functional groups and 2,4,6-trichlorophenol.
