Abstract

The level and undulation of scattered light can be effectively suppressed by magnetic field effects-polarization-resonant synchronous fluorescence spectrometry. The established technique was used for simultaneous determination of a sample mixture containing fluorene, acenaphthene, anthracene, benzo-[a]-pyrene (B-[a]-P) and perylene. The detection limits were 0.23, 7.90, 0.13, 1.10, 0.0083 ng ml(-1) for fluorene, acenaphthene, anthracene, B-[a]-P and perylene, respectively. The relative standard deviations were less than 5%.
