A multicomponent analysis of the sorption of polydisperse ethoxylated nonionic surfactants to aquifer materials: equilibrium sorption behavior
Article Abstract:
The effectivity of a surfactant-based aquifer remediation method that relies on ethoxylated nonionic surfactants lies in the interaction of the various components of the surfactant both with the aquifer material and the liquid medium. Surfactant critical micelle concentration governs the sorbed and solution surfactant distribution. For remediation, surfactants with lower ethoxylate units are found to be sorbed to a greater extent and achieves a sorption plateau at lower solution concentrations.

NAPL compositional changes influence partitioning coefficients
Article Abstract:
Investigations into the measurement capability of the partioning interwell tracer tests on groundwater remediation techniques showed the testing technique's measuring ability compromised by the ability of the non-aqueous phase liquids (NAPL) to alter the partitioning coefficient of tracer compounds. NAPL treated to washings of cosolvent which simulated enhanced dissolution significantly altered the tracer's partitioning coefficient.
