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 0.20 μg/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.
