Pollution is Inefficiency Products Raw Materials PROCESS (Any Activity) Energy Time Waste
Nanotechnology for Environment with nano iron Remediation of Groundwater Organic solvents (TCE, PCE) Pesticides (DDT, lindane) Fertilizers (nitrate) Heavy metals (Pb, Hg, Cr, As) Explosives (TNT, RDX) Radioactive materials (U) Perchlorate (ClO4-) • TCE reduction with nano Iron • Oxidation of pollutant enhanced by coupling with (Fe/Pd)* on the nanoscale. • Smaller size makes it more flexible -- penetrates difficult to access areas.
