In-situ treatment technologies have been proposed to transform or remove pollutants from contaminated groundwater. Zero-valent iron(Fe$^{0}$ ), metallic iron, is being evaluated as a permeable reactive material to retard the transport of wide array of highly mobile contaminants in groundwater. In this research, tetrachloroethylene(PCE) dechlorination by powdered zero-valent iron in buffered aqueous solution was studied with and without the presence of surfactants. The rate of dechlorination of PCE by zero-valent iron with surfactant was much higher than without surfactant. The presence of surfactant increased the apparent rate of dechlorination because the surfactants influenced the dissolution of PCE into the aqueous phase.
