• This study was focused on removal efficiency of PAHs from contaminated sediment using anionic surfactant: Triton X-100 (TX-100), Simple Green (SG)) and nonionic (Sodium dodecyl sulfate (SDS), Sodium dodecylbenzene sulfonate (SDBS)) surfactants. In this study various operating parameters were investigated such as surfactant concentration, liquid/solid ratio, washing time, and washing frequency. The maximum removal efficiency evaluated was 68% obtained by using TX-100 (100 CMC: 19 mM). The optimized factors for the evaluation were liquid/solid ratio of 20 with 1 h each washing time and 20 times washing frequency. The result were significantly influenced due to frequency of soil washing, surfactant concentration; liquid/solid ratio; and washing frequency while excessive operating parameter caused decreased in removal efficiency.
