摘要：The soil near a mine tailing was remedied by electrokinetic method with different electrode mate-rials(e.g., graphite, stainless steel and titanium plate). The variations in removal efficiency and soil pH with treatment time were determined. The removal efficiency of Lead reached a maximum of 76.95% when using a voltage gradient of 1 V/cm and treated for 48 hours with graphite electrode; higher than 64.17 % of Lead removal efficiency was obtained with stainless steel electrode, and 54.15% of total Pb removal with titanium plate electrode. The improved removal efficiency was attributed to the more active sites for transfer of electrons provided by graphite electrode, compared to the stainless steel and titanium plate electrode.
