The Efficacy of Oxidative Coupling for Promoting In-Situ Immobilization of Hydroxylated Aromatics in Contaminated Soil and Sediment Systems
Hydroxylated aromatic compounds (HACs) are common subsurface contaminants at many industrial sites, including DOE facilities. Under certain conditions, HACs can undergo oxidative coupling reactions that may lead to their sequestration, reducing their environmental mobility and toxicity. Mineral oxides and enzymes naturally present in most soils can catalyze these coupling reactions. We proposed to investigate (1) the role of abiotic/enzymatic coupling reactions on the sequestration of hydroxylated aromatic compounds (HACs) by natural geosorbents, (2) the effects of sorbent structure and chemical compositions on such processes; and (3) the conditions for induction of these biotic/enzymatic coupling reactions by addition of suitable catalysts and sorbents. Information gathered from this study will be useful in quantifying the behavior of this class of organic compounds in various subsurface contamination scenarios relevant to DOE facilities, and in specifying strategies for the selection and design of remediation technologies.
