our team contact us site map	Nanotechnology: Cleaning up our Water Summary posted by Meridian on 3/31/2008 Source: Ivanhoe Broadcast News Author: n/a A researcher from Rice University in the U.S. has developed a method for using gold and palladium nanoparticles and hydrogen to break down trichloroethylene (TCE), a common industrial solvent used to degrease metals that can potentially cause cancer, in groundwater. According to the article, the nanoparticles are held in place by glass beads in an apparatus through which water is pumped and leaves treated. The researcher, Michael Wong, says that he will first test the technology at military sites and then at industrial sites and dry cleaning businesses. Wong further says that the new apparatus will be cheaper and more efficient than currently used carbon reactors. The article can be viewed online at the link below.
