FUNDAMENTAL STUDIES OF THE REMOVAL OF CONTAMINANTS FROM GROUND AND WASTE WATERS VIA REDUCTION BY ZERO-VALENT METALS

PDF Version Also Available for Download.

Description

Oxyanions of uranium, selenium, chromium, arsenic, technetium, and chlorine (as perchlorate) are frequently found as contaminants on many DOE sites. A potential remediation method is to react the contaminated water with zero-valent iron (ZVI). In this reaction, the iron serves as both an electron source and as a catalyst. Elemental iron is already being used on an experimental basis at many sites. Both in situ reactive barriers and above-ground reactors are being developed and field tested at this time. However, the design and operation of these treatment systems requires a detailed process-level understanding of the interactions between the contaminants and ... continued below

A potential remediation method is to react the contaminated water with zero-valent iron (ZVI). In this reaction, the iron serves as both an electron source and as a catalyst. Elemental iron is already being used on an experimental basis at many sites. Both in situ reactive barriers and above-ground reactors are being developed and field tested at this time. However, the design and operation of these treatment systems requires a detailed process-level understanding of the interactions between the contaminants and the iron surfaces. We are performing fundamental investigations of the interactions of the relevant compounds with Fe filings and single- and poly-crystalline surfaces. The aim of this work is to develop the fundamental physical and chemical understanding that is necessary for the development of cleanup techniques and procedures.
