In this study, splittable surfactants, Triton SP series, were used since their surface active properties can be easily changed by adjusting the pH value, which is convenient for later treatments of the contaminated flushing solutions. Experiments were performed to examine the foaming ability, foam stability, and solubilization efficiency of surfactant solutions. Moreover, an experimental column containing pentadecane-contaminated glass beads was built to explore the effects of foam property and flow rate on the overall efficiency in contaminated soil remediation. The results demonstrated that the foaming and solubilization abilities of surfactant Triton SP-190 solutions were better than Triton SP-175. Therefore, Triton SP-190 solutions were selected to perform the foam-enhanced column flushing experiments. From the results of column flushing experiments, it can be concluded that the higher the surfactant concentration, the higher the oil-removed efficiency. Furthermore, if only water or a surfactant solution was used in column flushing experiments, channelling flows were always abserved, resulting in lower flushing efficiency. Thus, the foam-enhanced flushing approach was found to improve the flushing efficiency since the channelling flows can be avoided. In addition, at a constant liquid flow rate, the flushing efficiency was increased as the gas-liquid ratio was increased. Chang Chien-Hsiang 張鑑祥 1999 學位論文 ; thesis 88 zh-TW |

Experiments were performed to examine the foaming ability, foam stability, and solubilization efficiency of surfactant solutions.
