| Abstract: | A new series of task-specific ionic liquids (TSILs) containing hydroxyl groups was prepared and applied for extracting 4-nonylphenol (4-NP) and 4-tert-octylphenol (4-t-OP) in water. These new TSILs showed much greater extraction efficiencies for 4-NP and 4-t-OP than the common typical ionic liquids 1-butyl-3-methylimidazolium hexafluorophosphate (C4mim]PF6]) and 1-hexyl-3-methylimidazolium hexafluorophosphate (C6mim]PF6]).  Additional information ACKNOWLEDGMENTS This work was supported by the National Natural Science Foundation of China (20377025) and the Scientific Research Foundation of Southwest University of Science and Technology (06ZX7116). |
