Dispersed Zero-Valent Iron Colloids

SUMMARY

Stable dispersions of zero-valent iron particles are produced by milling of micro- and nano-scale iron particles (colloids) in the presence of a dispersant or dispersants. The present invention is a process for preparing zero-valent iron suspensions which can be used directly at the source of the pollution, applied to deep aquifers, and spread over large areas of contaminated soil or water.
