Feasibility of using metals to remediate water containing TCE

Abstract:
The feasibility of treating underground water contaminated by a chlorinated organic compound with bimetallics Fe/ Ni, Zn/Ni and Zn single metal was studied. Column tests to simulate a reactive permeable wall in a funnel-and-gate system were used. Research results indicated that bimetallic Fe0/Ni0 and Zn0/Ni0 all had a very strong degraded power to trichloroethylene (TCE) at concentration up to 25 mg/l under different flow rates (27 cm/day-20 m/day). Furthermore, the concentrations of TCE and various ions in the treated effluent were nearly lower than the values specified in related standards for drinking water in Taiwan. These results showed that this technique could be effectively and safely used as an underground water remediation process.
