N2 - The distribution coefficients for phenols (phenol, o-cresol, m-cresol, p-cresol, 3,5-xylenol and α-naphthol) in ionic liquid (1-butyl-3- methylimidazolium haxafluorophosphate ([bmim][PF6]))/water two-phase system were measured at 298 K to examine a removal ability of phenols in wastewater by the liquid-liquid extraction. Judging from these distribution coefficients, it is feasible that phenols can be extracted from wastewater by using the present ionic liquid. The infinite dilution distribution coefficients of phenols obtained in this study were correlated by the regular solution theory. Further, ASOG, which is one of the successful group contribution activity coefficient models, was applied and the group interaction parameters were determined. The correlated results based on the above two models are in good agreement with the experimental results.
