A study was performed on the removal of 2,4,6-trichlorophenol (TCP) from synthetic polluted soils using electrokinetic soil flushing (EKSF) assisted by a granular activated carbon-permeable reactive barrier (GAC-PRB). The polluted soils consist of spiked kaolin and were obtained by directly mixing kaolin with a 200 mg dm(-3) TCP solution. Remediation tests were conducted at the bench-scale. The obtained results demonstrated that EKSF assisted with GAC-PRB is a very efficient technology for the removal of TCP from soils. For a given remediation period, the applied electric field is a very important parameter that influences the removal efficiency. Under optimized conditions, the one week-long remediation test obtained removals greater than 80% with energy consumptions below 200 kWh m(-3). The effects of the electric field on the temperature and TCP profiles were also assessed and explained in terms of ohmic drops and electrokinetic processes.
