IRON NANO-PARTICLES
February 1st, 2004
BY MATTHEW BRACEAUSTRALIAN researchers have developed what they say is a cheaper and safer way of producing iron nano-particles crucial for cleaning up contaminated sites, notably those containing waste solvents. The particles chemically modify polluting compounds by removing chlorine atoms, replacing them with hydrogen atoms. This makes the target compounds less toxic and easier for natural microbes to break down. The new technology will be of interest to the solvents industry which uses chlorine-based chemicals regularly and may have contamination issues ...
