The goal of this project is to ultimately come up with guidance for application to actual groundwater remediation schemes. Sequential Desorption of CBDA from CBDA-Hectorite.
Bioremediation is considered one of the most attractive decontamination processes for PAHs.
Because insitu biodegradation of PAHs is very slow, additional action is often needed to keep a contaminant plume from migrating to nearby water supplies before complete biodegradation has occurred. Cationic surfactants hold the potential to substantially increase the soil's sorption capacity for contaminants and reduce their mobility, allowing sufficient time for biotransformation to take place. This research examines that feasibility. Confirmed that the amount of CBDA irreversibly sorbed is in the interlayer region. The results imply that PAHs, such as phenanthrene, can be most effectively immobilized at low surfactant coverage.
