The improper storage, usage, and treatment would result in leakage of chlorinated solvent to subsurface environment. The sub-surface pollution caused by chlorinated solvent has been caused considerable attention recently. Electrochemical geooxidation technology (ECGO) was applied oxidation electrodes into contaminated soil and resulted in migration and degradation of contaminants after given direct current. ECGO is an innovative in-situ remediation technology, which overcome the disadvantage of migration only in Electrokinetic process. The advantages odf ECGO technology includes: (1) production of uniform electroosmosic flow in heterogenous medium, especially in low permeable soil; (2) easy control of flow direction; (3) high removal and degradation efficiency; (4) high economy. A one-year project was proposed for application of ECGO technology on 1,2 dichlorobenzene contaminated soil and investigation of degradation mechanism. It is expected to develop an innovative sustainable remediation technology for chlorinated solvent contaminated soil. The research works are described as follows, — Establish the preparation method for Binnary oxidation electrode. The electrochemical properties of electrode will be characterized by cyclic voltammetry. The surface characterestics and coating amount of electrode will be investigated by Scanning electron microscppy and Thermogravimetric analysis, TGA, respectively. The stability of electrode in electrolyte will be also investigated. — Conduct a bench-scale ECGO experiment to evaluate the degradation performance of 1,2 DCB in soil. The investigated parameters include electrode type and electrolyte solution.
