The technology involves the preparation of dispersions of zero-valance nanoscale iron particles and one of soy protein, soy milk, or other soy derivative. The dispersions can be used to treat contaminated soil or water.
Dispersions can be injected directly into soil and groundwater for site remediation. Soy protein, a natural substance devoid of any known adverse environmental impact, can stabilize and enhance the mobility of the zero-valent iron particles in the subsurface environment.
