Arsenic traps
Supercomputers have been used to design new chemicals with flypaper-like arsenic-trapping properties. The developers of the chemical hope to test the new material, called Specific Anion Nanoengineered Sorbents (SANS), at a planned city water-purification demonstration plant in Albuquerque, as well as in several smaller water systems in rural New Mexico communities. Researchers think the new arsenic-eating SANS could reduce the sticker shock of removing arsenic from drinking water for cities served by water treatment plants.
