A study on relation of Pb treatment and pH variation characteristics during Electrokinetic remediation of clayey soil

점성토에서의 Electrokinetic 정화기법에 의한 납 제거와 pH변화 특성의 상관성에 관한 연구

In treatment of contaminated ground by electrokinetic remediation, pH control is the main prolllem for enhancinfi remediation efficiency. In this study, analysed pH variation characteristics according to contaminant(Pb$^{2+}$) concentration and estimated remediation efficiency with organic acid to prevent precipitation in cathode due to hydroxide ion occurrence. Because most of transported Pb$^{2+}$ is precipitatecl according as pH is increased at specimen adjacent to cathode reservoir, little magnitude of Pb$^{2+}$ is flowed out of specimen.cimen.
