Study of Manganese Dioxide Reduction during the Transformation of Organic Pollutants
EMSL Project ID
2161
Abstract
This proposed project would use technology at the EMSL to study the reduction of manganese dioxide which has been exposed to organic pollutants, specifically 2,4,6-trichlorophenol. Currently, it is thought that XPS technology can be used to indentify the proportions of Mn (IV) , Mn (III), and possibly Mn (II) as manganese dioxide is reduced. This data would provide insight as to the reductive mechanism of manganese dioxide, which is currently believed to be a two step process. Manganese dioxide itself is found throughout the environment and is thought to be a powerful naturally occuring mineral. Understanding its reductive mechanism could help lead to understanding its role in the abiotic transformation of pollutants in the environment.
