Study on Electrokinetic Remediation of PBDEs Contaminated Soil

Electrokinetics is a soil remediation technology under development. One of its advantages is that it can realize in suit remediation. A series of bench-scale experiments were carried out and result showed that electrokinetic technology was effective in promoting BDE15 desorption and migration in soil, and its effect depends on the type of electrodynamics. Ion concentration was changed for the electrolysis reaction, and lead to current changed. The current variation tendency was increase first then decrease.Soil pH and temperature was changed as a result of electric field, soil resistance and temperature increases, the cathode temperature up to 40 degrees C.
