PBDE Analysis with SPE and LLE

Researchers from Central China Normal University (Wuhan, China), Wenzhou Medical College (Wenzhou, China), and East China University of Science and Technology (Shanghai, China) extracted polybrominated diphenyl ethers (PBDEs) from water and plant samples using solid-phase extraction (SPE) and dispersive liquid–liquid microextraction (DLLME). They used gas chromatography with electron-capture detection for the final analysis. They obtained relative recoveries of PBDEs spiked into well water, river water, seawater, leachate, and clover samples ranging from approximately 62% to 110%.
