Small Technology to Clean Up Big Pollution Problems

EPA scientists are exploring ways to use some very small materials to clean up some very big environmental troubles. Research chemist Dr. Souhail Al-Abed and his colleagues have synthesized stimulated carbon with nanoparticles of iron/palladium bimetallic to construct a new nano-scale treatment to clean up pollutants. The new, tiny technology is offering promise where unadventurous technologies have been limited in detecting, treating, removing, and preventing environmental contaminants.

The research is proving particularly useful in dealing with PCBs, a family of persistent organic chemicals that have been linked to a host of dangerous health effects, including cancer. Dr. Al-Abed and his research group found that infusing the carbon with nanoparticles not only made it more effective at adsorbing contaminants, but also degraded the PCBs to less dangerous compounds.
