摘要
为了解决同时测定纺织品中多种酚类化合物的问题,建立了气相色谱质谱法(GC-MS)同时测定纺织品中17种酚类化合物的分析方法。样品用氢氧化钾溶液(2 mol/L)超声提取,将提取溶液与乙酸酐衍生化反应。衍生产物经正己烷提取后,采用GC-MS检测,选择离子模式(SIM)扫描,内标法定量分析。该方法在0.05～0.5μg/mL范围内呈良好的线性关系,相关系数(r2)≥0.999 0;方法的定量限为0.05 mg/kg,平均回收率为89.3%～117.6%,相对标准偏差小于9.3%。结果表明,该方法准确、灵敏,可用于纺织品中17种酚类化合物的分析测定。
To solve the problem of simultaneous determination of multiple phenols in textiles,a method for the determination of 17 phenols in textiles was developed by using gas chromatography-mass spectrometry（GC-MS）.The sample was extracted with potassium hydroxide（2 mol/L） by ultrasonic treatment,and then the extract was reacted with acetic anhydride.The derivative was extracted by hexane and determined by GC-MS.Data were acquired in the selected ion monitoring（SIM） mode and quantified by internal standard method.Good linearity relation was observed at the mass concentration range of 0.05-0.5 μg/mL with a correlation coefficient（r2） above 0.999 0.The limits of quantification（LOQs） were 0.05 mg/kg,and the average recoveries were in the range of 89.3%-117.6% for 17 phenols with the relative standard deviations below 9.3%.This method is proven to be accurate and sensitive,and is suitable for the analysis of 17 phenols in textiles.
