【摘要】：本文建立了气相色谱-质谱法(GCMS)检测运动场地塑胶面层中18种多环芳烃的方法.样品经乙酸乙酯超声萃取60 min,取上清液,加入内标混合溶液(萘-D8、蒽-D10和傒-D12等3种内标),用GCMS分离和检测.结果表明,多环芳烃在5—200μg·L~(-1)浓度范围内标准曲线线性良好,相关系数均在0.999以上.在5.0μg·L~(-1)浓度下,连续6次进样,峰面积RSD值均小于10.0%,精密度良好.以3倍信噪比(peak to peak)计算18种多环芳烃的检出限,以10倍信噪比(peak to peak)计算18种多环芳烃的定量限,各组分的检出限为0.09—0.8μg·kg~(-1),定量限为0.27—2.4μg·kg~(-1).在1.0 mg·kg~(-1)的加标浓度下,样品加标回收率为83.2%—129.7%.该方法简单方便,能够有效的监测运动场地塑胶面层中多环芳烃的含量.
[Abstract]:A gas chromatography-mass spectrometry (GCMS) method for the determination of 18 polycyclic aromatic hydrocarbons (PAHs) in the plastic surface layer of sports site was established. The sample was extracted by ethyl acetate for 60 min and the supernatant was extracted. The standard curves of polycyclic aromatic hydrocarbons (PAHs) in the concentration range of 5-200 渭 g 路L ~ (-1) were linear well, and the correlation coefficients were above 0.999, and at the concentration of 5.0 渭 g 路L ~ (-1) of polycyclic aromatic hydrocarbons (PAHs), the internal standard solution (naphthalene -D8, anthracene -D10 and D12) was added to the internal standard solution for the separation and detection of polycyclic aromatic hydrocarbons (PAHs) in the concentration range of 5-200 渭 g 路L ~ (-1). The peak area RSD value was less than 10.0, and the precision was good. The detection limits of 18 PAHs were calculated by using 3 times signal-to-noise ratio peak to peak, and the quantitative limits of 18 PAHs were calculated by 10 times signal-to-noise ratio peak to peak. The detection limit of each component was 0.09-0.8 渭 g 路kg ~ (-1) 路kg ~ (-1) and the quantitative limit was 0.27-2.4 渭 g 路kg ~ (-1) 路kg ~ (-1). The recovery rate was 83.2 ~ 129.7% at 1.0 mg 路kg ~ (-1) 渭 g 路kg ~ (-1). The method was simple and convenient, and could effectively monitor the content of polycyclic aromatic hydrocarbons (PAHs) in the plastic layer of sports site.
