摘　　要：建立了快速检测鞋类塑料中烷基酚(APs)的气相色谱-质谱联用法(GC-MS)。样品采用超声萃取,对萃取溶剂、萃取温度、萃取时间3种条件分别进行了优化。萃取液过滤后用GC-MS检测,外标法定量。结果表明,烷基酚在0.1~10 mg/L浓度范围内呈良好的线性,相关系数(r2)均大于0.995,方法检出限为0.3~1.1 mg/kg,在3个加标水平下的平均回收率为80.7%~113.3%,相对标准偏差(RSD,n=6)为1.3%~8.6%,该方法简单、快速、准确、稳定可靠,适用于鞋类塑料中APs的检测。A method for determination of alkylphenols in the plastics for footwear productions was developed by gas chromatography mass spectrometry.The samples were obtained from ultrasonic extraction,and the extraction solvent,temperature and time were optimized.After purified with a membrane filter,the extracts were quantitatively determined by a GC-MS method,and then their quantification was performed by an external standard method.The calibration curves of alkylphenols were linear in the range of 0.1~10 mg/L with correlation coefficients(r2)more than 0.995.The detection limit was in the range of 0.3~1.1 mg/kg.The spiked average recoveries varied from 80.7%to 113.3%at three spiked levels with the relative standard deviations(n=6)of 1.3%~8.6%.The method developed by this work was simple,rapid,accurate,stable,and reproducible for determination of alkylphenols in the plastics for footwear productions.
