摘　　要：建立了基于交替三线性分解的化学计量学辅助三维室温磷光法(ATLD-TRTP)快速准确检测大气污染源样品中多环芳烃苊(ACE)的方法。对采集的大气污染源,如餐厨油污、油烟气和烟囱灰等样品,经过简单的样品预处理后,采用荧光光谱仪的磷光模式进行测量,并对获得的激发发射矩阵三维磷光数阵采用ATLD算法进行分解。在n=5时,获得ACE的平均回收率分别为90.5%±7.9%、99.4%±6.1%和101.4%±10.9%,预测均方根误差(RMSEP)分别为0.25、0.12和0.20μg/mL,检出限(LOD)分别为39.2、18.9和31.0 ng/mL。结果表明,ATLD-TRTP方法能够在背景干扰共存下,快速检测大气污染源样品中ACE的含量,且方法准确、绿色环保,为研究大气颗粒物中PAHs的来源提供了一种很有潜力的分析手段。A new method based on alternating trilinear decomposition assisted three-dimensional room temperature phosphorescence(ATLD-TRTP)was developed for fast quantitative determination of acenaphthene(ACE)contents in samples of air-pollution source.The contents of ACE in air-pollution source samples,such as greasy dirt,oil smoke and flue dust in Loudi city were detected after simple sample pretreatment.Using ATLD algorithm(n=5),the average recoveries of ACE were 90.5%±7.9%,99.4%±6.1%and 101.4%±10.9%,respectively,the root-mean-square errors of prediction(RMSEP)were 0.25,0.12 and 0.20μg/mL,respectively,and the limits of detection(LOD)were 39.2,18.9 and 31.0 ng/mL,respectively.The results showed that the ATLD-TRTP method was suitable for the determination of ACE in air-pollution source samples even in the presence of uncalibrated interferents.
