Quantification of Brominated Flame Retardants in Synthetic Polymers via Direct Mass Spectrometric Analysis.

ABSTRACT: Brominated flame retardants (BFRs) are persistent organic pollutants commonly encountered in plastics. Herein, we report on the quantification of BFRs directly from plastic samples via direct insertion probe mass spectrometry (DIP-MS). The study was conducted using model polymer samples comprising either acrylonitrile butadiene styrene copolymer (ABS) or high impact polystyrene (HIPS) and a BFR, namely decabromodiphenyl ether (decaBDE), hexabromocyclododecane (HBCD), or tetrabromobisphenol A (TBBPA). DIP-MS enabled direct quantification of decaBDE and TBBPA from both ABS and HIPS matrices. A linear correlation between BFR signal intensity and bromine (Br) content of the samples, as determined by X-ray fluorescence, was established over a Br concentration range of 0-7 wt %, or even higher.
