Abstract: 

Electro kinetic remediation is a promising technology for contaminated clayey soils. In order to estimate the efficiency of process on different soils, knowing the interaction of simultaneous different processes is very important. The results of electro kinetic process are water flow, ion and species migration against an electrical field.
In this paper the feasibility of phenol removal from kaolinite using Electro kinetic remediation is investigated. Results of three one dimentional tests at constant current condition are presented. The tests were conducted for about 50 hours. Variations of pH, electrical gradient, electro osmotic flow and phenol concentration in anode and cathode chambers as well as soil specimen were measured.
The efficiency of phenol removal along the soil specimen was calculated at the end of each test. In one case more than 80 percent of phenol removal was achived from soil sample. Results indicated that electro kinetic remediation is suitable for phenol removal from contaminated clayey soils in short time. Further experiment needed to evalute the efficiency of this technology on contaminant removal of natural polluted soils.
