Could Rusty Iron Help Detoxify the World?

According to Fresh Innovators, oxides that form on rusting iron make excellent agents to detoxify various types of chemical spills. Until recently, producing them was itself a hazardous process. But, by using nanoparticle sized pieces of iron, Dr Andrew Feitz says a vastly cheaper, and potentially more effective method is around the corner. More information is available at the University of New South Wales.
