Abstract
Reduction of Trichloroethene (TCE) contaminated ground water by the zero-valent metals is a fairly new method of passive remediation. Several field applicable potential catalysts for use with the zero-valent metals iron and zinc in the reduction of TCE were evaluated. It was determined that both copper and nickel coatings on iron can improve the degradation rate of TCE. The best degradation rates for TCE were observed using the trimetal system of copper and nickel coatings on iron. Degradation rates of TCE were improved by up to six times over that observed in non-coated iron standards. Intermediary daughter products formed in the iron standard experiments predominantly consisted of cis-1,2-dicloroethene and 1,1-dicloroethene. Intermediary daughter products were generally not found in experiments with bimetal and trimetal systems. In both the standard experiments and in the trimetal and bimetal experiments, TCE ultimately was found to degrade into ethene and ethane gas.
