建立了聚碳酸酯树脂及其成型品中双酚A（BPA）的气相色谱-质谱联用（GC—MS）检测方法。样品经丙酮提取后挥发至干，用碳酸钾溶液溶解，再与乙酸酐衍生反应。衍生产物经正已烷提取后，采用GC—MS进行分析。结果表明，方法的线性范围为0．05—1．0mg／L，相关系数为0．9989，线性范围为1．0—10．0mg／L，相关系数为0．9999；方法的检出限为0．05mg／kg；平均回收率为93．0％-100．5％；相对标准偏差为4．2％-7．2％。该方法准确、灵敏，可用于实际聚碳酸酯树脂及其成型品中双酚A的分析。

The method for the determination of bisphenol A （BPA） in polycarbonate resin and its products was developed by gas chromatography -mass spectrometry（ GC -MS）.The BPA was extracted from polycarbonate resin and its products with acetone and concentrated by the evaporation of solvent. It was redissolved 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 0.05 ~ 1.0mg/L with a correlation coefficient of 0. 9989 ,the linear calbration curve was obtained in the range of 1.0 - 10, 0mg/L with a correlation coefficient of 0.9999 ;The detection limit of the method was 0.05 mg/kg; The recoveries were 93.0% - 100.5% ,and the relative standard deviations were 4.2% - 7.2% ;The method is accurate and sensitve, and it is suitable for the analysis of bisphenol A in polycabonate resin and its products.
