The subject investigated the effect of extraction time; oil/water ratio; surfactants nature and contaminant nature on separation effect; with n-hexane as extracting agent; benzene as the target pollutant; sodium dodecyl sulfate (SDS) and Tween 80 as surfactants through batch experiments. The results showed that; the optimum condition parameter of extraction was 2 h of extraction time and 0.1 of oil water ratio. For n-hexane; the effect of separating Tween 80 and benzene was better than SDS and benzene. And Tween 80 concentration had little effect on separation efficiency. The effect of separating benzene and SDS increased with the concentration of SDS firstly; then decreased with that of SDS; and at 1.375 CMC reached the optimum separation efficiency. For n-hexane; the effect of separating benzene and SDS was better than nitrobenzene and SDS. And the separation efficiency increased with the concentration of pollutants. There was competition between the separation of pollutants and SDS when benzene and nitrobenzene coexisted;
