摘　　要：建立了超高效液相色谱-串联质谱联用法同时快速测定纺织品中2种烷基酚的分析方法。通过实验条件的优化,样品用甲醇在60℃超声提取30 min,萃取液过滤后以C18色谱柱为分离柱,电喷雾负离子模式电离,多重反应监测模式测定,外标法定量。2种烷基酚在0.05~1 mg·L^(-1)浓度范围内呈现良好的线性关系,相关系数(r^(2))均大于0.995,方法检出限分别为0.25(OP)和0.34(NP)mg·kg^(-1),在3个不同浓度水平进行加标回收试验,平均回收率为81.7%~109.0%,相对标准偏差(n=6)为4.3%~9.2%。方法检出限低,分析时间短,适用于实际纺织品材料中烷基酚的分析检测。A rapid method based on ultra high performance liquid chromatography coupled with tandem mass spectrometry was established for determination of 2 alkylphenols in textiles.The conditions of experiment extraction were optimized.Samples were extracted with methanol at 60℃with assistance of 30 min ultrasound treatment.The extracted solution was filtered and eluted with C18 chromatographic column.The positive electrospray ionization and multiple reaction monitoring mode(MRM)was utilized.Quantification was performed by an external standard.The calibration curves of these alkylphenols were linear in the range of 0.05~1 mg·L^(-1)with correlation coefficients(r^(2))more than 0.995.The detection limits of compounds were 0.25 mg·kg^(-1)for OP and 0.34 mg·kg^(-1)for NP respectively.The average recoveries were 81.7%~109.0%at three spiked levels with relative standard deviation(n=6)of 4.3%~9.2%.The detection limit of this proposed method was low with a short analysis time.The method is suitable for the determination for alkylphenols in actual textile products.
