摘要
研究建立了超声萃取法测定丙烯腈-丁二烯-苯乙烯共聚物(ABS)木塑家具中16种多环芳烃(PAHs)的气相色谱-质谱(GC-MS)方法。以代表性的6种多环芳烃做条件选择,通过正交试验优化,甲苯为提取剂,60℃超声0.5h,萃取液通过气相色谱/质谱-选择离子监测法进行定量分析,16种多环芳烃线性相关系数均大于0.995,方法检出限范围为0.01~0.09 mg/kg,平均回收率80.4%~108.3%,相对标准偏差(n=6)小于10%。该方法简便快速、灵敏度高、定量准确,满足ABS木塑材料中16种多环芳烃的检测要求。
The GC-MS method was established for determining contents of 16 Polycyclic aromatic hydrocarbons（PAHs） in acrylonitrile butadiene styrene copolymers （ABS） wood plastic composites. The typical 6 PAHs were chosen as the condition and optimized by orthogonal experiment. The sample was dissolved by toluene with 0.5 h ultrasonic extraction at 60 ℃, and then was analyzed by GC-MS with selected ion monitor technique. The correlation coefficients of the 16 PAHs were more than 0.995, and the method detection limit ranged from 0.01 to 0.09 mg/kg. The average recovery of 16 PAHs was 80.4%- 108.3%, and the relative standard deviation （n=6） was less than 10%. The results showed that this method was simple, rapid, sensitive and accurate, which could completely satisfy the demand of the analysis of 16 PAHs in ABS wood plastic composites.
