Sorption of perchloroethylene by surfactant-modified zeolite as controlled by surfactant loading

Article Abstract:

The general configuration and fractional organic content of organic compounds are crucial factors in determining the sorption rate of surfactant-modified zeolite molecules. These factors were found to cast a significant impact on the effective volume and density of organic phases, which in turn, enhance the partitioning mechanism of surface-active compounds. Experimental results further reflected a marked correlation between PCE sorption behavior and surfactant monolayers and bilayers.

Partitioning of hydrophobic organic compounds to sorbed surfactants. 1. Experimental studies

Article Abstract:

Experiments on hydrophobic organic compound (HOC) partitioning to surfactants have provided evidence that surfactant sorption to the solid phase can increase HOC retardation in certain equilibrium conditions. The study however, finds the method undesirable for surfactant-enhanced remediation applications and finds that consideration of sorption and HOC partitioning to different phases are important considerations in determining applications.

Partitioning of hydrophobic organic compounds to sorbed surfactants. 2. Model development/predictions for surfactant-enhanced remediation applications

Article Abstract:

A model to determine the effectivity of surfactant-enhanced remediation (SER) applications for hydrophobic organic compounds (HOC) is shown to provide useful guidelines for designing and deploying SER applications. The model computes surfactant losses by sorption to the subsurface media and for HOC partitioning thereafter and is also found to be effective for interpreting SER-related studies.
