Electrokinetic Removal of Chlorinated Aliphatic Hydrocarbons

a family of compounds that are commonly used as organic solvents, have been increasingly detected in soil and in groundwater. The most prevalent CAHs

To enhance the remediation of CAHs, the EK process coupled to other technologies has been developed. For instance, the EK process was used to transport Fenton agents for the remediation of TCE-contaminated soils (Yang and Liu, 2001). EK- 

Generally, significant removal of CAHs from soils can be achieved by the EK process. The EK removal of CAHs was affected by both the sorption behavior of CAHs on soils and the EO flow (EOF). On one hand, the sorption of CAHs on 

EOF in order to achieve a high removal efficiency in a short time. In general, the pH of the anodic purging solution should be controlled at a relatively high level as a decrease in pH led to a decrease in EOF. The removal of CAHs from soils can be promoted by the EK process coupled to other processes.
