A method for the detection of polybrotuohiphenyls (PBBs) and polybromodiphenyl ethers (PBDEs) in electrical and electronic equipments by gas chromatography-mass spectrometry ( GC-MS) has been developed. The pretreatment procedures, such as solvent selection, extraction method and column type, were discussed, and standard mass spectral library of PBBs and PBDEs was established. Four qualitative methods of retention time, isotopic rule of bromine, characteristic ion and standard library searching were used. The detection limit was 5 mg/k,, and the recovery rate of PBBs and PBDEs was 92.5% and 91.3%, respectively. The relative standard deviation was 4.3%. The separation time was 6 minutes, results meeting the directions of RoHS were obtained. This method can be used to analyze the bromine-based flame retardant in electrical and electronic equipments, plastic, rubber and decorative materials of car.
