Polybrominated diphenyl ethers (PBDEs) are a group of widely used brominated flame retardants. Due to their extensive use, increasing levels of PBDEs have been found in humans, fish, birds, marine mammals, sediments, house dust, air, and supermarket foods. As a new environmental pollutant, a feasible in-situ remediation method is needed. In situ remediation methods for PCBs have been developed at UCF using palladium/magnesium bimetal created by mechanical alloying. A thorough investigation of PBDE-47 with this bimetal pair was performed. The bimetal was very reactive with 92% reduction of PBDE-47 within 36 hours. This presentation will focus on the kinetic studies as well as byproduct identification.
