The Characteristics of Electrokinetic Remediation for Unsaturated Soil

불포화토의 동전기정화 특성에 관한 실험적 연구

In this study, a series of electrokinetic(EK) remediation experiments are carried out under the different degree of saturation for contaminated soil with lead. for constant electrical potential, the final current of all the sample represents the similarity to steady-state value of 5∼7mA. Under conditions of all the degree of saturation the anode reservoir becomes acidic(pH as low as 3) while the cathode reservoir is basic(pH as high as 12). But pH changes in the sample is a little and decontamination efficiency is the low.
