Nanoscale Iron Colloids

David B. Vance: Nanoscale iron is a material that is generating interest as a groundwater remediation technology for the reductive dehalogenation of various solvents, treatment of oxyanions such as chromate, and other constituents that may respond to strong abiotic reductive processes such as perchlorate. During initial development, it was thought that the unique character of nanoscale particles was due solely to the small size. Current studies show that the structure and composition of the particle is also critical to both reactivity and longevity. These newly understood relationships could have measurable implications for advancing the maturity of the technology as a practical tool for in-situ remediation.
