초록
After kaolin clay was compulsorily contaminated by Sr$^{2+}$ solution, the remediation characteristics by electrokinetic method were analyzed. Meanwhile, the numerical code for analysis of electrokinetic migration was developed for modelling of the soil remediation. Experimental results are as follows After 3 day remidiation under 40 voltage, the front part of experimental cell was almost decontaminated, but the behind part didn't almost be decontaminated. Accordingly, the total remediation ratio of Sr$^{2+}$ from cell soil was about 42.6 %. Also, the total Sr$^{2+}$ remediation ratio from cell soil was about 84.8 % after 6 days, and about 97.1 % after 7 days. Meanwhile, the values calculated by the developed code almost agreed with experimental values.ues.
