Nanoporous ceramic hoovers up mercury
Researchers at Pacific Northwest National Laboratory, US, have used functionalized nanoporous ceramics to remove mercury from water. The thiol self-assembled monolayers on mesoporous silica (or thiol-SAMMS) could have applications in treating wastewater from coal-fired power stations, a major source of the pollutant. “There is a pressing need for mercury-removal technology that offers high selectivity, adsorption capacity, improved kinetics and a stable waste form,” Shas Mattigod of Pacific Northwest National Laboratory told nanotechweb.org.
