The Efficacy of Oxidative Coupling for Promoting In-Situ Immobilization of Hydroxylated Aromatics in Contaminated Soil and Sediment Systems

PDF Version Also Available for Download.

Description

Many hydroxylated aromatic compounds (HACs), particularly small molecules such as substituted phenols, are common contaminants of surface and subsurface systems. The high environmental mobility of these contaminants, due to their relatively high water solubilities, is of particular concern. Abiotic and enzymatic oxidative coupling of this class of contaminants by natural sorbents may be significant in controlling the mobility of HACs and facilitate remediation efforts. The principal objectives of this study are to investigate: (1) the role of abiotic/enzymatic coupling reactions on the sequestration of HACs by natural sorbents; (2) the effects of sorbent structure and chemical composition on such sequestration; ... continued below

Description

Many hydroxylated aromatic compounds (HACs), particularly small molecules such as substituted phenols, are common contaminants of surface and subsurface systems. The high environmental mobility of these contaminants, due to their relatively high water solubilities, is of particular concern. Abiotic and enzymatic oxidative coupling of this class of contaminants by natural sorbents may be significant in controlling the mobility of HACs and facilitate remediation efforts. The principal objectives of this study are to investigate: (1) the role of abiotic/enzymatic coupling reactions on the sequestration of HACs by natural sorbents; (2) the effects of sorbent structure and chemical composition on such sequestration; and (3) optimal conditions for the induction of these abiotic/enzymatic coupling reactions by addition of suitable catalysts and sorbents. Information gathered from the 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.
