Study on the Electrokinetic Remediation Technology of Cr (VI) Polluted Soil

Abstract:

Electrokinetic remediation is in-situ remediation technique. Potassium dichromate was chosen as the pollutant and its initial concentration was 500mg·kg-1 in Kaolin soil. This experiment, we are to study the feasibility ,the factors which influence the whole course, including applied voltage, treatment time, soil moisture, OH^- produced at the cathode and its control. It indicate that, there is separating out oxygen at anode, hydry at cathode. Cr₂O₇^2-and CrO₄^2- absorb electron to change to Cr³⁺, and unite to Cr (OH)₃. The experiment results show OH^- produced at the cathode has crucial effects on the removal efficiency of chromium; secondly the applied voltage and treatment time have important influence on the efficiency, and the soil moisture affects the efficiency in some degree.
