Abstract
Surfactant-based remediation has received considerable attention as a potential technology for enhancing conventional pump-and-treat remediation processes for aquifers contaminated with organic nonaqueous-phase liquids (NAPLs). In surfactant remediation, NAPL contaminants can be removed by two processes: solubilization and mobilization. Although these processes have been extensively studied, limited information is available regarding the partitioning of nonionic surfactants between aqueous and organic phases. Because surfactants are amphiphilic molecules that have a finite solubility in aqueous phases and NAPL, partitioning between the two phases is expected. The study presented here examines the effect of surfactant and NAPL properties on the partitioning of nonionic surfactants between different aqueous and nonaqueous phases using ethoxylated nonionic surfactants with different chemical structures and mixture distributions and NAPLs covering a wide range of NAPL/water interfacial tensions. In general, ...
