Abstract
In this study, variation on electrochemical parameters and characteristics of lead immobilization due to phosphoric acid injection in soil were studied during electrokinetic remediation of lead contaminated soil. To do this, electric potential, electric current and electroosmotic flow rate were measured during electrokinetic treatment of lead spiked illitic soil and variation of pH and TCLP value of lead were analyzed after test. After electrokinetic treatment with phosphoric acid and hydrochloric acid, TCLP result showed about 100% of soil was satisfied TCLP regulation criteria. And injected ion from cathode reservoir by ionmigration was proportionate to concentration of phosphoric acid and elapsed time. Therefore, when removal is infeasible or not cost-effective, in situ immobilization method would be more effective.
