Study develops mercury-absorbing sponge

Researchers from the University of Minnesota College of Food, Agricultural and Natural Sciences have developed a sponge capable of absorbing mercury contamination at high rates, according to an article in Interesting Engineering. The sponge, which uses a thin selenium surface over the polyurethane sponge, nanotechnology can absorb mercury from industrial wastewater in five minutes. The article says, “If Como Lake (not to be confused with Italy’s Lake Como) which spans 280,000 square meters was contaminated with mercury at the EPA’s limit, it would only take a basketball-sized sponge to remove the mercury.” The sponge also converts the substance, make it biodegradable.
