Second-derivative constant-wavelength synchronous scan spectrofluorimetry for determination of benzo[b]fluoranthene, benzo[a]pyrene and indeno[1,2,3-cd]pyrene in drinking water

The use of derivative constant-wavelength synchronous scan fluorimetry is reported for the determination of three polycyclic aromatic hydrocarbon pollutants in drinking water (linearity range 0.4-4 mug 1(-1)). The limits of detection (LD) and quantification (LQ) (mug 1(-1)) are 0.01 and 0.07 for benzob]fluoranthene, 0.03 and 0.12 for benzoa]pyrene and 0.19 and 0.57 for indeno1,2,3-cd]pyrene in the presence of three other pollutants, benzok]fluoranthene, benzoghi]perylene and fluoranthene. The precision (RSD /= 85%) were satisfactory.
