Experimental Study on Electrokinetic Remediation of Chromium Contaminated Soils

摘要

The efficiencies of electrokinetic remediation of Chromium contaminated soils were researched by means ofrnexperiments in this paper. The influence of electrolyte of chromium on electrokinetic processes was inspected, and migration andrnvariation characteristics of chromium were analyzed as well. The results indicated that under the same conditions, addingrndifferent electrolytes have a significant impact on the overall distribution of Cr in soil, and for Cr (Ⅵ) removal was less affected.rnDistilled water was added to the electrolyte and KNO_3, Cr in the3 # soil region peak appeared, resulting in enrichment effect.rnThus, the present experiment, the electrolyte KH_2PO_4 is best results achieved.
