Abstract

Zero-valent iron (ZVI) is currently employed to remediate ground water contaminated with TCE, however the mechanism of the dechlorination reaction is not well understood. In order to compare the mechanism of ZVI-mediated dechlorination to that of a well characterized phosphino-iron(0) model complex, dechlorination of TCE with ZVI was studied in organic solvents. The reaction was carried out with 100 mesh iron(0) in oxygen and water-free conditions using THF and toluene as solvents. TCE loss was monitored by GC/MS. The reaction in water-free THF resulted in complete degradation of TCE after several days, but only a 10% decrease in TCE concentration was observed in water-free toluene over the same timescale. The dechlorination reaction in water-free toluene with tert-butanol as a proton source was also evaluated.
