Remove toxic mercury from water in seconds
Most, if not all, of us know that mercury is a toxic substance. It can be absorbed through the skin and mucous membranes while mercury vapors can be inhaled. Its effect can include damage to brain, kidney and lungs not only to human beings but also animals. The greater danger is in waters when the toxin is not immediately known as it is hidden from naked eyes.
Researchers from University of Minnesota (UMN) discovered a sponge that removes mercury from water. This was through the application of nanotechnology. The sponge is a simple memory foam and coated with nano-layer of selenium. After absorbing the toxin, the sponge converts the contamination into non-toxic material so the sponge can be safely disposed as regular non-toxic waste afterwards.
