A method of supercritical CO2 fluid extraction gas chromatography-mass spectrometry (GC-MS) was developed for the determination of 2 novel brominated flame retardants (BB-153 and TBECH)) in flexible polyurethane foam. The optimum conditions as follows: extraction temperature: 60°C, pressure:30Mpa, CO2 mass flow rate: 8g/min ,flow rate of methanol entrainer: 3mL/min and extraction time: 60min. The calibration curves were linear in the range of 0.1~50μg/mL with correlation coefficient of 0.9995~0.9999 and detection limits (S/N=20) of 0.05μg/mL. The average recoveries of the target compounds in sample were in the range of 97.3%~98.8%(BB-153)、99.2%~105.8% (TBECH) respectively. The results showed that this method was sensitive, reliable and environmental for the determination of 2 novel brominated flame retardants (BB-153 and TBECH)) in flexible polyurethane foam.
