摘    要:采用微波辅助萃取法提取塑料制品中的多环芳烃,并采用高效液相色谱法对其进行了测定。该方法所用色谱柱为多聚C18(LC-PAH)柱,流动相为乙腈/水,采用梯度淋洗方式,开始时为40%乙腈,28min后变为82%乙腈,48min后变成100%乙腈,保持8min。该方法的线性范围为0.099~200mg/L,线性相关系数为0.9993~0.9999,平均回收率为60.7%~109.8%,其相对标准偏差(RSD)为0.6%~8.8%,检出限(信噪比S/N=3)为0.05~0.1mg/kg,完全可以满足塑料制品中多环芳烃的检测要求。

关 键 词:多环芳烃  高效液相色谱法  塑料制品

Abstract:PHAs in plastic products were extracted by microwave-assist extraction, and a HPLC method was established to determine the contents of PAHs in plastic products. The analysis was carried out in a reversed-phase polymer C18 (LC-PAH) column by gradient elution with acetonitrile/ water as the mobile phase. The content of acetonitrile was 40% at the beginning , then changed to 82% after 28min, and varied to 100% after 48min, and maintained for 8min. The linear range was 0.099 to 200mg/L with coefficients of 0.9993 to 0.9999. The average recovery varied form 60.7% to 109.8%, and the relative standard derivation ranged from 0.6% to 8.8%. The limits of detection was 0.05 to 0.10mg/L at S/N=3. This method could satisfy the demand of analysis of PAHs in plastic products.
Keywords:PAHs  HPLC  Plastic product
