Abstract

One of the challenges in analytical chemistry has been the determination of polybrominated-dibenzodioxins (PBDD) and polybrominated dibenzofurans (PBDF) in resin matrices containing brominated diphenylethers as flame retardants. This is mainly because brominated diphenylethers severely interfere with PBDD/PBDF analyses. A new method which eliminates this problem is described below. This new procedure effectively removes the brominated diphenyl ethers in the sample, or reduces them to a level where mathematical corrections can be made. In addition, a new approach is used which allows isomer-specific determination of PBDD/PBDFs without the need for a complete set of analytical standards. Results from the use of this method in the analysis of PBDD/PBDF in flame retarded ASB resins and processing fumes are presented.
