%X Partition characters of phenol,aniline and p-nitrophenol in sediment-anionic surfactant sodium dodecylbenzene sulfonate(SDBS) system were researched. The results indicated that the sediment-water partition coefficients K of aniline and p-nitrophenol increased when the initial concentrations were set at 200mg/L and 1200mg/L for SDBS. The positive relation was found between partition enhancement and the Kow of the reference organic compounds. But the K of phenol was different from that of aniline and p-nitrophenol in SDBS system with initial concentration set for 1200mg/L and it was lower than that in pure water. The data showed that in sodium dodecyl sulfate(SDS), Triton X-100(TX100) and Brij30 systems respectively, the sorption of phenol on the sediment was enhanced by surfactants below their critical micelle concentrations(CMCs),but it was diminished above the surfactant CMCs.
