摘　　要：建立了纺织染整助剂中6种邻苯二甲酸酯的测定方法。采用DB-5 ms作为分离柱,用气相色谱-质谱联用仪对样品中的邻苯二甲酸酯进行分离和测定。所有组分彼此完全分离,能同时予以定性确认。6种邻苯二甲酸酯在一定浓度范围内线性关系良好,相关系数R≥0.99;最低检出限远低于法规要求。本方法具有高选择性、灵敏度和准确度,完全满足纺织染整助剂中邻苯二甲酸酯含量的测定要求。A gas chromatography-mass spectometry method for determination of six PAEs in textile dyeing and finishing auxiliaries was established. Six PAEs in textile dyeing and finishing auxiliaries were separated by GC with an DB-5MS capillary column and analyzed by MS. The results showed that all PAEs were separated completely each other,and simultaneously identified and quantified. Each correlation coeficient of all calibration curves was good（ R≥0. 99）,and between defined concentration range. The limit of detection of six PAEs was much lower than regulatory requirements. The method was selective,sensitive,and accurate; it could be apply to qualify and quantify the six PAEs in textile dyeing and finishing auxiliaries.
