New Material Shows Promise for Trapping Pollutants
September 6, 2011
Water-softening techniques are very effective for removing minerals such as calcium and magnesium, that occur as positively charged ions in "hard" water. But many heavy metals and other inorganic pollutants form negatively charged ions in water, and existing water-treatment processes to remove them are inefficient and expensive. Chemists at University of California, Santa Cruz, have now developed a new type of material that can soak up negatively charged pollutants from water.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
