In this paper, three surfactants, sodium dodecyl sulfate (SDS), sodium dodecyl benzene sulfonate (SDBS) and polysorbate 80 (Tween80), were selected to study the solubilization of petroleum hydrocarbons-contaminated soil. The solubilization effect of surfactants on petroleum pollutants in soil was investigated by batch experiments, and the effect analysis and suitability evaluation were also conducted. The results showed that: (1) The optimal concentrations of SDBS, SDS and Tween80 for the solubilization of petroleum hydrocarbons in contaminated soil were 6, 10 and 15 g·L^-1, respectively, the best solid-liquid ratios were 1:15, 1:20 and 1:15 (g·mL^-1), and the best treatment time were 12, 12 and 24 h, respectively. The solubilizing ability of the three surfactants within the scope of each investigation factor was always SDBS > SDS > Tween80. Since non-ionic surfactants were more affected by soil adsorption, resulting in a lower effective concentration, the solubilization effects of the anionic surfactants selected in the study were better than those of non-ionic surfactants. (2) The compound of anionic-nonionic surfactants could reduce the repulsion between the same type of surfactants. The combination of SDS, SDBS and Tween80 had synergistic solubilization effect, and the more the proportion of SDS and SDBS in the system, the higher the elution rate of petroleum hydrocarbon. Because of the differences in structure and properties, the three surfactants showed different coordination for petroleum hydrocarbons. After compounding with the appropriate electrolyte promoter of Na₂SiO₃, the elution performance was enhanced, and the order was SDBS (97.56%) >SDS (97.24%) > Tween80 (92.71%),
