  • Process for producing a nanoscale zero-valent metal
    Patent number: 8283034
    Abstract: This invention describes a process for producing a nanoscale zero-valent metal, including reduction of a metal ion solution with a dithionite compound, wherein the reduction is carried out under alkaline conditions under substantially an inert atmosphere. A nanoscale zero-valent metal obtainable by this process, and having a new crystalline form, is also described. The nanoscale zero-valent metal produced by the process of the invention is preferably iron, and is advantageously used for the remediation of contaminated water.
    Type: Grant

  • Method for Decontaminating Surfaces
    Publication number: 20070256713
    Abstract: A method for treating a surface to decontaminate the surface by chemically altering contaminants on the surface. The method comprises applying to the surface particles of a zero valent metal capable of reacting with oxygen and water to form hydroxyl radicals, and exposing the particles to oxygen and water. The method may be carried out in the presence of air.
