For those working to clean up some of the worst water pollutants on Earth, gold and palladium might be getting considerably more precious.
Rice University researchers have been working with the metals for a decade to figure out a way to efficiently destroy complex chemical pollutants. They have announced that the fruit of their labor is a technology called PGClear that they say can quickly decontaminate groundwater. Scientists from Rice, Stanford University and DuPont collaborated on the work, which will first be installed in June at a DuPont plant in Kentucky.
At its heart, the system uses pellets formed from a combination of the two metals. The pellets act as a catalyst to break down persistent cancer-causing industrial solvents like vinyl chloride, trichloroethene and chloroform into nontoxic methane and salt byproducts.
