摘要:The soil near a mine tailing was effectively remedied by electrokinetic method with different electrode materials (graphite, stainless steel, titanium plate), and the variations in removal efficiency and soil pH with treatment time were determined. The removal efficiency of cadmium reached a maximum of 63.16% when using a voltage gradient of 1 V/cm and a treatment time 48 h with the graphite electrode. When using a stainless steel electrode, cadmium removal efficiency was >43.46%, and 39.82% of total Cd could be removed with a titanium plate electrode. The improved removal efficiency was attributed to the more active sites for transfer of electrons provided by the graphite electrode, compared to the stainless steel and titanium plate electrode.
