Nanoscale Iron Particles: Synthesis, Characterization, and Applications

Wei-xian Zhang
Lehigh University, Bethlehem, PA

Iron nanoparticle technology is receiving considerable attention for its potential as a remedial method for a wide variety of common environmental contaminants. Nanoparticles have small sizes for in situ injection and dispersion, large surface areas and high surface reactivity for contaminant transformation. In this lecture, fundamental principles on nanoparticle synthesis and characterization will be highlighted. Applications of the iron nanoparticles for treatment of chlorinated organic solvents, organochlorine pesticides, PCBs, perchlorate, and hexavalent chromium will be presented. In addition, key issues related to field applications such as cost, fate/transport, and potential environmental impact will be discussed.
