摘要
Accelerated dechlorination of soil and water contaminated with chlorinated solvents in situ is achieved by delivering ferric ammonium citrate into the soils and/or water. The induction of ferric ammonium citrate into sulfate-rich reducing conditions initiates a combined abiotic and biotic mechanism for the dechlorination of subsurface contaminants. Initial and rapid removal of chlorinated solvents is achieved by way of reductive transformation, a mechanism utilizing the creation of an iron-bound soil mineral (pyrite) followed by stimulating conditions for enhanced biological natural attenuation.
