| 摘 要： | 建立了一种快速测定纺织品中13种邻苯二甲酸酯的热裂解-气相色谱-质谱分析(Py-GC-MS)方法,优化了热裂解仪分析条件:初始温度200℃,以50℃/min升温至350℃,保持2 min。该方法线性关系良好,线性相关系数R2>0.99,检出限为0.08~6.17 mg/kg,回收率为89.2%~97.1%,相对标准偏差为1.2%~4.4%(n=6)。该方法前处理简单快速,精密度较好,定性可靠,可满足纺织品中13种邻苯二甲酸酯的日常检测要求。

| Abstract: | A method for rapid determination of 13 phthalates in textiles by pyrolysis gas chromatographymass spectrometry(Py GC-MS)is established.The optimized analytical conditions of the pyrolyzer are the initial temperature of 200℃,heating to 350℃at 50℃/min,holding for 2 min.The linear correlation coefficient is R2>0.99,the detection limit is 0.08-6.17 mg/kg,the recovery is 89.2%-97.1%,and the relative standard deviation is 1.2%-4.4%(n=6).The method is simple,rapid,accurate and reliable,which can meet the daily detection requirements of 13 phthalates in textiles. |
