PNNL develops mercury-absorbing pollution solution

Scientists at the Department of Energy's Pacific Northwest National Laboratory have developed a novel material that can remove mercury and other toxic substances from coal-burning power-plant waste water. PNNL's synthetic material features a nanoporous ceramic substrate with a specifically tailored pore size and a very high surface area. The surface area of one teaspoon of this substance is equivalent to that of a football field. "This substance has proven to be an effective and voracious tool for absorbing mercury," said Shas Mattigod, lead chemist and PNNL project manager. Pore sizes can be tailored for specific tasks.
