Study finds advantages to iron nanoparticles for environmental clean up

A new study says some iron nanoparticles may be effective in cleaning up carbon tetrachloride in contaminated groundwater

Researchers at Oregon Health & Science University's OGI School of Science & Engineering, in collaboration with Pacific Northwest National Laboratory (PNL) and the University of Minnesota, have discovered that at least one type of nano-sized iron may be useful in cleaning up carbon tetrachloride contamination in groundwater. The new discovery was published Dec. 16, 2004, in Environmental Science & Technology, the leading environmental journal of the American Chemical Society. The study will be published in the print version of Environmental Science & Technology, March 1, 2004, in a special section on nanotechnology.
