Use of Soy Proteins or Soy Derivatives and Zero-Valent Iron for Environmental Remediation

SUMMARY Lehigh has developed a novel material for the treatment of contaminated water and soil. The method for the preparation of such materials involves the dispersion of zero-valance nanoscale iron particles and use of either soy protein, soy milk, or other soy derivatives. These particles have large surface areas, giving them increased reactivity...

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...
