Effect Of Metal Speciation In Fly Ash On Environmentally Persistent Free Radical Formation, Elisabeth Eileen Cook

LSU Doctoral Dissertations

Waste incineration and Superfund sites lead to the formation of pollutants harmful to both the environment and human health. Environmentally Persistent Free Radicals (EPFRs) are a class of newly discovered radical pollutants known to form on combustion by-products such as fly ash and particulate matter. EPFRs are rapidly gaining attention for their harmful effects on the environment and human health. Previous research has shown the formation of EPFRs through surface-mediated reactions with transition metal-oxides on particulates. The work presented in this dissertation explores the relationship between fly ash composition and EPFR formation. Fly ash production occurs from combustion systems, namely …
