Influence of Complexes on Electrokinetic Remediation in Chromium Contaminated Soil

LU Jing, ZHU Kun, HOU Bin, ZHAO Yan-feng (School of Environmental and Municipal Engineering,Lanzhou Jiaotong University,Lanzhou 730070,China)  
Experimental study was done on electrokinetic remediation of chromium-polluted soil at laboratory scale. The addition of EDTA and citric acid obviously changed the quantity of current and Cr(Ⅵ)distribution in soil during electrokinetic remediation process,in which citric acid increased the mobility of total Cr tremendously in soil by 78.4% due to stronger complexation action of citric acid with Cr(Ⅲ) in soil. Concentrations of all residual Cr(Ⅵ) in soil decreased greatly, especially after adding complex. In comparison with none of adding complexes,the adding of complexes could significantly enhance the mobility by 40%.
