Iron and bimetallic nanoparticles have shown immense promise for dechlorination of trichloroethylene (TCE) in water. However, application of these materials is not simple due to problems with material synthesis and oxidation during storage. In this work, iron and bimetallic nanoparticles are immobilized in a thin, polymeric membrane which combines absorption of the organic compound and dechlorination. This paper with discuss material synthesis and application of iron, iron-nickel, and iron-palladium membrane-supported nanoparticles for TCE dechlorination.
