摘要：
A method for the determination of tetrabromobisphenol-A (TBBP-A) in electronic products was developed by gas chromatography-mass spectrometry (GC-MS). The TBBP-A was extracted from electronic products by automatic digestion oven with acetone and concentrated by the evaporation of solvent. It was redissolved in methylene chloride, back-extracted by potassium carbonate solution and reacted with acetic anhydride. The derivative was extracted by hexane and determined by GC-MS. The linear calibration curve was obtained in the range of 0.25 - 5.0 mg/L with a correlation coefficient of 0.996. The detection limit of the method was 0.05 mg/kg. The recoveries were 87.3% - 104.1% and the relative standard deviations were 5.6% - 8.5%. The method is accurate and sensitive, and it is suitable for the analysis of tetrabromobisphenol-A in electronic products.
