Simple synchronous fluorimetric method for determination of benzo[a]pyrene in airborne particulates without a pre-separation procedure

  • Published:
Wuhan University Journal of Natural Sciences

Abstract

A sensitive analytical method, constant-energy synchronous fluorimetry, has been used to determine benzo[a]pyrene (BaP) selectively in airborne particulates (AP). A constant-energy difference of 1 400 cm−1 was selected for obtaining single spectral peak. The method could easily identify BaP in an 18-component polycyclic aromatic hydrocarbons(PAHs) mixtures. Calibration plots in methanol solution and in sodium dodecylsulfate (SDS) micellar media show a good linearity (R>0.999) in the BaP concentration range generally found in the environment. The method gives a detection limit of 0.40 nmol/L in SDS micellar medium and 1.34 nmol/L in methanol solution.
