Effects of solution chemistry on the partitioning of phenanthrene to sorbed surfactants

Article Abstract:

Solution chemistry creates varying effects on surfactant micelle formation, surfactant sorption on kaolinite and phenanthrene partitioning to surfactant micelles and sorbed surfactants. In the case of anionic surfactant sodium dodecyl sulfate, an increase in ionic strength creates a decreasing effect on critical micelle concentration (CMC). In the case of nonionic surfactant Tween 80, changes in ionic strength and pH do not affect CMC.

Effects of solution chemistry on the partitioning of Phenanthrene to sorbed surfactants

Article Abstract:

The results of a study of solution chemistry effects on surfactant sorption on kaolinite, surfactant micelle formation, and phenanthrene partitioning to sorbed surfactants and surfactant micelles are presented. For sodium dodecyl sulfate, an anionic surfactant, increasing ionic strength caused a decrease in critical micelle concentration values, but pH changes had no impact on such values.
