摘  要：Sensitive detection of tetrabromobisphenol A (TBBPA) and its derivatives, a group of emerging toxic contaminants, is highly necessitated in environmental investigation. Herein a novel analytical strategy based on reactive extractive electrospray ionization (EESI) tandem mass spectrometry for detection of tetrabromobisphenol A bis(2-hydroxyethyl ether) (TBBPA-BHEE), tetrabromobisphenol A bis(glycidyl ether) (TBBPA-BGE), tetrabromobisphenol A bis(allylether) (TBBPA-BAE), and tetrabromobisphenol S bis(allylether) (TBBPS-BAE) in industrial waste water samples was developed. Active silver cations (Ag + ), generated by electrospraying a silver nitrate methanol solution (1002mg02L 611 ), collides the neutral TBBPA derivatives molecules in the EESI source to form [M02+02Ag] + complexes of the analytes under the ambient conditions. Upon collision-induced dissociation (CID), characteristic fragments of the [M02+02Ag] + complexes were identified for confident and sensitive detection of the four TBBPA derivatives. Under the optimized experimental conditions, the instrumental limits of detection (LODs) of TBBPA-BHEE, TBBPA-BGE, TBBPA-BAE and TBBPS-BAE were 0.37, 0.050, 0.76, and 4.602μg02L 611 , respectively. The linear ranges extended to 100002μg02L 611 ( R 2 02≥020.9919), and the relative standard deviations (RSDs), inter-day variation and intra-day variation were less than 7.8% ( n 02=029), 10.0% ( n 02=025), and 14.8% ( n 02=021 per day for 5 days) for all derivatives. TBBPA derivative manufacturing industrial waste water, river water and tap water samples were fast analyzed with the proposed method. The contents of TBBPA derivatives were various in the collected samples, with the highest 19.902±020.302μg02L 611 of TBBPA-BAE in the waste water samples.
