technology water purification with help "a clever rust" and magnets] is create

Researchers use nanoparticles of oxide of iron for removal from water of polluting substances. About technologies reports American chemical society. Researchers developed nanoparticles from iron oxide , intended for water purification. "The clever rust" collects various pollutants, including oil, tiny particles of plastic and even hormones. Nanoparticles possess magnetic properties, it is easy to remove them from water together with polluting substances with help a magnet. As a basis researchers use nanoparticles of oxide of iron in a superparamagnetic form. They are attracted to...
