The Study of Cd and Pb Characteristics on Electrokinetic Remediation of Mine Deposit

Electrokinetic 기법에 의한 광산퇴적토내 Cd과 Pb의 제거 특성에 관한 연구

In the remediation of contaminated soil by electrokinetic process, transport characteristics of contaminants are major factors. Pb is highly fixed to entire soil and not moved readily. High concentration of Cd was analyzed in the cathodic section but anodic section's concentration was lower than initial concentration. Although the Cd had high treatment effect, 50% of total mass was concentrated in cathodic section and was not flowed out readily. Most of transported Cd may be adsorbed in the cathodic side soil due to increased pH at adjacent to catholyte.
