Advances in in-situ electrochemistry-kinetic remediation technique for organic pollutants in soil-groundwater

Advances in the in-situ electrochemistry-kinetic remediafion technique for organic pollutants in the soilgroundwater system are summarized. The in-situ electrochemistry-kinetic remediation technique is based on the principal that the water and charged ions and particles in the soil pores are moved by electredialysis, electromigration and electrophoresis. The effectiveness of electrochemistry-kinetic remediation can be affected by the factors of the pH value of the soil, soil type, electric current, voltage and electrode characteristics. The large amount of research results show that the in-situ electrochemistry-kinetic remediation technique can remove the organic pollutants in the soil-groundwater system effectively. It is a remediation technique for organic polluted soft with great development potential.
