摘　　要：建立了纺织品中8种邻苯二甲酸酯的气相色谱-质谱分析方法。样品经乙酸乙酯微波萃取后，采用气相色谱-质谱仪的全扫描，选择离子扫描模式同时进行定性和定量分析。结果表明，该方法中8种邻苯二甲酸酯在0．5～20μg／mL范围内线性相关系数为0．997-0．999，样品加标回收率为88．2％～107．2％，精密度在1．3％～6．9％。与常规检测方法相比，该方法简单、高效、稳定性强，可实现多种邻苯二甲酸酯的同时检测。A determination method of 8 phthalates in textiles by GC-MS method is established. The phthalates in samples are detected with SCAN/SIM mode by GC-MS after microwave extraction. The results show that the correlation coefficients, recovery rate and relative standard deviation （RSD） are 0.997-0.999, 88.2%-107.2%, and 1.3%-6.9%, respectively. Compared to the other methods, this method is simple, effective, and can be applied for the simultaneous determination of various phthalates.
