Mechanisms of surfactant-enhanced air sparging in different media.
TL;DR: The results demonstrated that when air traveled in the form of channels, a decrease in surface tension accordingly reduced capillary pressure in porous media, thereby considerably improving contaminant removal and can serve as theoretical bases for SEAS application in contaminated sites.

Insights on Flow Behavior of Foam in Unsaturated Porous Media during Soil Flushing
TL;DR: The results demonstrated that foam has a stronger capacity of lateral spreading, besides, foam flow was uniformly distributed across the foam-occupied region, regardless of the heterogeneity of porous media.

Transport characteristics of nanoscale zero-valent iron carried by three different “vehicles” in porous media
TL;DR: SDS solution and SDS foam were better vehicles than water for delivering nZVI particles to porous media for contamination remediation and the mobility of nZ VI in finer sand was significantly enhanced by foam, compared with that in coarse sand.

Application of Counter-Current Solvent Extraction to the Separation of Naphthalene and Nonionic Surfactants
TL;DR: In this article, the influence of solvent/solution volumetric ratio, solvent flow rate, and surfactant concentration on counter-current solvent extraction efficiency was investigated, and fitting formulas for predicting the partition coefficients of the contaminant between the aqueous and solvent phases were developed.

Laboratory evaluation of the use of solvent extraction for separation of hydrophobic organic contaminants from surfactant solutions during surfactant-enhanced aquifer remediation
TL;DR: In this article, a series of batch experiments were conducted to verify the effectiveness of solvent extraction by describing the interactions among contaminants, surfactants, and solvents, using factors such as extraction time, solvent/water volumetric ratio and surfactant type and concentration.
