Nanoparticles clean up arsenic
Abstract:
Researchers at Oklahoma State University, US, have used nanoparticles of zinc oxide to remove arsenic from water, even though bulk zinc oxide cannot absorb arsenic. They produced the zinc oxide in a porous aggregate form that was suitable for water treatment. “Nanoparticles have already been demonstrated to have useful absorption and catalytic properties but there wasn’t a way to take advantage of them in the real world due to their small size,” researcher Satish Kuriyavar told nanotechweb.org.
