Development of Numerical Analysis Program Considering Variation of Soil Properties During Electrokinetic Remediation

Electrokinetic 정화 처리 중 토체내의 특성변화를 고려한 수치해석 프로그램 개발

In this study, the electrokinetic remediation test for the kaolin contaminated by lead was performed and voltage, zeta potential, pH distribution, current, contamination transport in soil sample were studied and finite differential numerical analysis program(HERP) for a contaminated soil were compared with those of test. From the result of HERP, in the anode it was represented that the rest concentration was decreased with the voltage. Hence, if treatment time was continued for a long in the constant voltage, comparing with sample having no change in the rest concentration, it is considered that the voltage gradient is the control factor of the rest concentration.
